Industry News, Trends and Technology, and Standards Updates

We live in a world where cell phone upgrades have become a way of life. Some people upgrade every time a new phone is available so that they can have the latest, greatest features and gadgets. Others prefer to keep their old phone since they are familiar with how it works and are satisfied with the phone’s functionality. While others still may upgrade because they have encountered a problem with their current phone that either can’t be fixed or has been addressed in the new model.

There are similar reasons to upgrade to a new version of a Cimetrix product. Here are a few sample questions that will help an OEM determine when is the best time to do so:

1. Is there an issue my customers are currently facing that has been addressed in the new version of the product?

Cimetrix works to fix customer-reported issues as well as issues found during internal testing. It is not possible to make these fixes in all previously released versions of the product, so they are made as a fix in the latest released version of the product. Upgrading to the latest version benefits the OEMs by providing fixes to issues they may have reported or, more often, to issues they haven’t seen but have been reported by other OEMs.

2. Are there added features or capabilities in the new version of the product that will improve my ability to support my customers and/or allow me to provide new functionality to my customers?

Cimetrix strives to support our customers by providing high-quality software products. As new technologies emerge and as scenarios in which our products are used evolve, we discover new ways to provide additional benefits to our OEM customers. These new capabilities are made available in new releases of our products. These improvements can include things like enhanced logging and diagnostic capabilities, new utilities for managing configuration files, or new screens for making setup easier.

3. Am I planning a new release of my equipment control software?

Like Cimetrix, OEMs are continually looking for ways to improve their equipment and provide new features and functionality to their customers. This means that they will periodically release new versions of their equipment that may contain new hardware and/or software functionality. This is an ideal time for OEMs to also upgrade their Cimetrix software so that their new platform can take advantage of the latest fixes and enhancements that are available.

This is by no means meant to be an exhaustive list of questions to be asked/answered when determining the right time to upgrade to a new version of a Cimetrix product, but it does give you an indication of the type of things that should factor into your decision-making process. Each new software release has a set of Release Notes that describe the software fixes and new features that have been added in that release. These Release Notes are there to help you make the best determination as to when to upgrade, so be sure to read them carefully. And, as always, the Cimetrix Support team is available to answer any questions and provide additional information if you should need it.♦

Cimetrix and our new distribution partner, Linkgenesis, participated in a joint booth at SEMICON Korea last week in Seoul. With over four exhibit halls located in the COEX Convention and Exhibition Center, SEMICON Korea is the largest SEMICON in terms of number of visitors—about 40,000—and included over 1,870 booths in 36,000 sq. meters of show space. The theme of the show was “Connect to Future, Market, People and Technology” with keynote speakers from leaders at Synopsys, Texas Instruments, and Audi. The show was co-located with LED Korea. Included in the schedule was also a meeting for the Information and Control Technical Committee, Korea Chapter, to work on SEMI standards.

Korea remains the second largest equipment market for the second year in a row, and represents the largest region of installed 300mm fab capacity in the world. This show has more equipment manufacturers, in my opinion, than most SEMICON shows. So, because of the show’s location, it made it an ideal opportunity for us to meet with our current worldwide equipment manufacturing customers who seemed to be present in every row, and to meet the growing list of Korean equipment manufacturers as they build volume and increase their expertise. We already have several customers in Korea and expect this number to grow over the next few years.

Our new partnership with Linkgenesis was founded on providing EDA/Interface A solutions in Korea; currently Samsung and Hynix are both looking at incorporating this technology into their manufacturing systems. As the world leader in EDA/Interface A, Cimetrix can provide superior expertise to make the adoption process efficient and successful. Linkgenesis already has business with most Korean equipment manufacturers, so, by combining forces, we bring strong local engineering support together with our world-class EDA solution, CIMPortal™ Plus.

To accelerate our penetration into Korea, we have hired Mr. Hwal Song (+82 (0) 10-5058-0895) as our Korean General Manager to accelerate our customer introductions and partnership with Linkgenesis. Song has a long history in the semiconductor software industry.

We met with several new potential customers during the show setting a strong foundation for our continued growth in the Korean market. We left the show feeling very positive about Cimetrix’ entry into Korea.

At the Information and Control Technical Committee meeting, David Francis, Director of Product Management, represented Cimetrix. In the meeting there was an introduction to work being done by SEMI Japan related to Role Based Access Control (RBAC); however, this effort is still under development by the Japan Task Force. The North America DDA Task Force is starting discussions about Freeze 3 of the EDA Standards. Tom Salmon, Vice President Global Member Services and Standards, introduced information about the SEMI Automation Technology Committee that is working on the Smart Manufacturing initiate in support of efforts coming out of Industrie 4.0 and Industrial Internet Consortium. There was also an information share on the status of efforts around standards for Recipe Management Systems that address some of the concerns with the existing standards such as Recipe and Parameter Management (RaP).

SEMICON Korea 2016 as a whole was a success for both Cimetrix and the Korean semiconductor industry. Seoul was a great backdrop for the show and we look forward to returning next year with greater market penetration and the chance to catch-up with even more clients.♦

I recently read The Martian by Andy Weir. Since this information comes out on the first page of the book, I don’t think I’m spoiling too much to say that it is the story of an astronaut, Mark Watney, who is lost in a space storm on a mission to Mars. He is presumed dead by his crewmates and abandoned on the planet. Of course he is not dead and he has to use training, skill, ingenuity, and luck to survive long enough to be rescued. Several times throughout the adventure, he has to connect life supporting utilities, tanks, airlocks, and vehicles together using the connecting valves supplied on each component. Watney says, “I’ve said this many times before, but: Hurray for standardized valve systems!” This is obviously a work of fiction, but what would have happened if he had tried to attach a holding tank to the ascent vehicle but the valves had changed between versions?

Software customers should be able to have the same expectation as Mark Watney that the valves don’t change during the mission. In the case of software, we aren’t talking about physical valves. Rather we are talking about software interfaces and API method signatures. In a real sense, the consistency of these software signatures are as mission critical as the standardized valve connections were for the astronaut in The Martian. Changing the method signatures, at the very least, requires that the users of the software have to rebuild their applications. Often times such changes require software users to have to requalify their entire tool. This places undue burden on the users of the software. Software users should be able to reasonably expect that the interfaces and API remain constant through the life of the mission (i.e. within the version of the software including minor releases and patches). A side note on this topic: If Cimetrix product management determines that a piece of software has a bug or does not conform to the SEMI standards on which our products are based, changes will be made to correct the problem. Similarly, if NASA determined that one of their connectors did not conform to the spec, they would immediately resolve the issue for the item that was out of spec.

The Cimetrix release versioning process (see our January 14, 2016 blog) allows Cimetrix personnel and Cimetrix software users to be aware of what backward compatibility guarantees are made for a specific version of Cimetrix software.

We would like our software users to be able to say, “Hurray for compatible software versions!”♦

With unemployment rates at some of the lowest rates in 10 years, keeping good employees can be a challenge. Ownership in the company they work for is one benefit highly valued by many employees. We all want to be part of a growing business, make it successful, and know we will be rewarded for our hard work. Cimetrix wants to provide such ownership incentives to our employees and do it in such a way that is fair and motivating to the employees while being fiscally responsible to shareholders.

One of the impacts of the December 26, 2014 reverse stock split was the price per share value went up and number of shares went down. The pre-reverse stock split value went from $0.15 a share to a post-reverse stock split price of $1,500 a share (as of December 26, 2014). This reduction in shares and corresponding increase in share price made it fiscally impractical to use stock options as part of our incentive program moving forward. Therefore, the Cimetrix Board of Directors approved a transaction to perform a 1,000 to 1 forward split effective December 30, 2015.

The forward split transaction resulted in 3,928,000 shares outstanding as compared to the pre-forward split shares outstanding of 3,928 and decreased the share price by the same ratio. While the ownership position of all Shareholders remained the same pre and post forward-split, it adjusted the price per share to a much more manageable price for granting incentive stock options.

For Shareholders holding physical stock certificates, a letter of instruction from our Transfer Agent, Colonial Stock will be mailed out by February 1, 2016. Shareholders with stock in brokerage accounts should receive notification from their brokerage firm directly.

We believe this transaction will benefit both employees and shareholders by providing the right level of incentives to keep a smart and talented workforce.♦

Last November Linkgenesis Corporation, based in Seoul, became the official Korean distributor of Cimetrix’ EDA/Interface A solution CIMPortal Plus.

This partnership was a perfect fit as we at Linkgenesis have been providing software products and development services in manufacturing information automation systems and the software testing area since 2001. In November of 2014, Linkgenesis merged with IT-Innovation, a communication software solution provider for semiconductor and LCD factories.

In cooperation with Cimetrix, Linkgenesis will be delivering the globally-proven EDA solution to Korean customers, and will also provide enhanced XGem/XGem300 GEM Driver harnessed with CIMPortal Plus so that customers using XGem/XGem300 can easily adapt their equipment to provide EDA capabilities. XGem/XGem300 GEM Driver is a Linkgenesis’ software driver supporting SEMI 300mm standards and is based on XCom SECS Driver that has been proven reliable for more than 200 customers. Linkgenesis’ software testing tool, MAT (Machine Auto Tester), has also been largely used by Korean mobile companies and automotive companies such as Samsung Electronics, LG Electronics, and Hyundai automotive groups.

SEMI EDA/Interface A standards were originally established in 2006 with Freeze-I and then updated with Freeze-II in 2010, but Korean chipmakers have not actively adopted Interface A standards in their production processes. However this is beginning to change as Samsung Electronics released its plan to introduce Interface A on its pilot line last August and SK hynix also started discussion of introducing Interface A.

In addition, Samsung Electronics plans to build a new line at its Pyeongtaek, South Korea and SK hynix’ plants to increase its production line at Cheongju and Yicheon, South Korea. However, according to Gartner’s forecast, semiconductor equipment spending by Samsung Electronics and SK hynix are going to slightly decrease this year. Samsung Electronics will invest $11.4 billion, which is a 13.5% decrease from 2014, and SK hynix will invest $4.8 billion this year, which is a 10.6% decrease from 2014.

We believe this new partnership between Linkgenesis and Cimetrix will provide a great deal of advantages to Korean customers in this emerging market, and will promote the increased interest in EDA/Interface A technology for chip manufactures.

Linkgenesis will be exhibiting at SEMICON Korea 2016, which will be held in Seoul on January 27-29. Please stop by our booth in Hall C #1739 to see our product line as well as Cimetrix’ CIMPortal Plus, and discover how our software brings the latest innovations to the semiconductor manufacturing industry.♦

There are times in life when a surprise is a good thing. Like when you get a box of chocolates. We all remember the line from the movie Forrest Gump, “Life is like a box of chocolates, you never know what you’re gonna get.” When you install a new version of software however, surprises aren’t as enjoyable. With a new software release, customers need to be able to assess the effort and impact the new release will have on their current systems and procedures. Then they can evaluate whether the new features and functionality will be worth the effort to deploy the new software release. One way software companies can help communicate the impact a new software release may have on customers is by using a clearly defined release versioning procedure.

Change is good and software products that grow and mature over time, adding new features and eliminating unwanted behaviors, can remain healthy and viable over a long period of time. However, consistency and predictability are also important characteristics of good software products. So how do software companies balance these two seemingly competitive objectives?

Many software companies can do this is through the way they use software versioning. It is common for software companies to use a major.minor.patch.build software versioning scheme, for example iTunes 12.3.1. This type of software versioning allows the software company to communicate the scale and impact of the changes in the release to their customers. A change in the “major” release number indicates to customers that there are some significant changes in this release that may impact the way it interacts with the product. The customer will likely need to make code changes or procedural changes when upgrading to such a release. A change to the “minor” release number denotes that there are multiple changes in the release, but customers should see only minor, or possibly no changes, in the way they use the product. A minor release may include some small new features that could potentially require code changes if the customers wants/needs those new features. A “patch” release is generally used to address a specific issue and should not change the customer experience with the software. The build number is most often provided to help the software company when researching a question or customer reported defect.

Software versioning provides a way to set expectations with the customer about what is in the release and how it might affect the way they use the product. It can help take the surprise out of the process of installing a new software release. Life may be “like a box of chocolates,” but software releases shouldn’t be.♦

Last fall I was invited to attend the 30^th Anniversary Celebration for Rorze Corporation and their partner company ADTEC Plasma Technology. The event took place at the Fukuyama New Castle Hotel in Fukuyama, Japan on December 14, 2015. As you may know, Rorze is an official distributor of Cimetrix products in Japan so we have a long-standing relationship including Rorze handling Cimetrix products as well as being an investor in Cimetrix Incorporated itself.

Rorze was established in 1985 by Fumio Sakiya with an ambitious slogan and aim: Never follow the competition. We shall only develop and market products which we believe are superior to those already on the market, that is, products that will become global news. Originally starting with only six engineers, Rorze is now a global player in the semiconductor industry specializing in automation systems for transferring semiconductor wafers and liquid crystal displays.

On December 14 we gathered in Fukuyama for the celebration. With 28 tables and 250 guests attending, we celebrated with speeches from Rorze and ADTEC management and local dignitaries, and enjoyed a first-class Japanese meal complete with sake. There was plenty of time to meet new people, congratulate the two 30-year-old company members, and relax in traditional Japanese fashion.

The following day Rorze hosted a visit to the Itsukushima Shrine in Miyajima that is a UNESCO World Heritage Site. This is a Shinto shrine famous for its floating Torii gate and wild deer. After taking a short ferry ride to the island, we enjoyed a day of sightseeing and a traditional Japanese lunch near the shrine. The original shrine was built in the 6^th century, so there is plenty of history surrounding this world-class cultural site.

It was an honor to attend a proud moment in the history for our partner Rorze, and we wish them many years of success as the leadership transitions from Sakiya san to our good friend Fujishiro san. Cheers and congratulations.♦

With the new year, comes a major new initiative for Cimetrix to grow the markets for its products.  The company used the transition to 300mm manufacturing to establish a leadership position for its current product portfolio in the semiconductor industry. However, the company is starting to have success expanding into adjacent vertical markets that includes disk drive, display, LED, and photovoltaic. The objective of this new initiative is for Cimetrix to leverage its experience, technology, and product portfolio gained in the advanced semiconductor manufacturing industry to expand the markets for Cimetrix products. We will be exploring new opportunities in our current adjacent markets as well as possible new markets such as SMT and electronic assembly.

To head up this initiative, Ranjan Chatterjee has joined the company in the role of Vice President, Emerging Business and Technology Office. He will focus on extending and introducing Cimetrix’ portfolio of products into Industry 4.0 and Industrial Internet of Things (IIoT) initiatives by interfacing manufacturing equipment with big data and analytics tools. The data generated by devices connected via Cimetrix products can also be enlisted to bolster another methodology often used with lean manufacturing—Six Sigma. With the improvements in cloud and big data tools and infrastructure, one can use these methodologies on data with much bigger volume, velocity, and variety. This enables process control and a lack of variation of products. Processes can be monitored and corrected in real-time instead of inspecting machines merely at completion, and eventually this will help improve yields and reduce scrap. Specifically, manufacturers will need to establish a robust data infrastructure that works across the broader array of machines on the shop floor while breaking down protocol barriers so the machines can communicate effectively and in real time.

Manufacturers will also need to establish a bidirectional data flow so they are not only collecting information from equipment, but also pushing control back to the machines to optimize their usage. Manufacturers that can capture the right information, sift through it, and use it at the right time will be the ones that succeed.  Cimetrix intends to be a leader in enabling this vision. Ranjan’s decades of experience at Motorola and in the industry as a whole in software development, big data, cloud, process control, and lean manufacturing will enable Cimetrix to both adapt and develop products and partnerships to enable a robust ecosystem for a compelling solution.

Ranjan’s relationship with Cimetrix is not a new one as he is a former client. While at Motorola, Ranjan oversaw the development and deployment of a standards-based factory control system for SMT and assembly, which encompassed 24 factories around the world, and connected to over 20,000 pieces of equipment using the first generation of Cimetrix connectivity software. At that time, it was the leader in cell phone manufacturing and the largest purchaser of SMT equipment in the world. More recently, Ranjan has worked with companies developing and deploying systems using cloud technologies, big data analytics, and various modern technologies with a global software development team.

Ranjan is extremely excited to join the Cimetrix team as he sees many opportunities to leverage the latest cloud and big data analytics with Cimetrix core expertise and product portfolio into new markets for Cimetrix. He sees great potential for expanding Cimetrix in this new direction and we here at Cimetrix are looking forward to Ranjan leading the way.

I believe that 2015 will be viewed as a significant turning point in the history of Cimetrix. When I accepted the role and responsibility of president and CEO of Cimetrix in 2001, Cimetrix was a publicly traded company. In addition to the normal challenges of running a business, Cimetrix was required to comply with all SEC reporting obligations. When the Sarbanes-Oxley Act (SOX) imposed additional financial reporting obligations with increased internal controls, Cimetrix was required to spend even more time and money. I’ve always believed if you are going to do something, you should do it to the best of your abilities. Consequently, Cimetrix dutifully fulfilled its quarterly SEC reporting and SOX compliance obligations. Every year independent SOX auditors performed the required annual audit and their reports always concluded that there were no material weaknesses in our financial reporting or internal controls.

For a small company like Cimetrix, we can be proud of these accomplishments. We are very thankful to have had Jodi Juretich as CFO for these past eight years. Jodi managed the company’s financials and was responsible for preparing all of our SEC filings. For those of you not aware, the SOX laws include significant personal liability for the CEO and CFO in the event of any material errors or misstatements. As a result, while we had no idea how many people might read our SEC filings (other than the fact that we know our competitors all meticulously read each and every one), each filing had to be reviewed not only internally, but also by SOX compliance consultants, auditors, lawyers, and the board of directors. Significant management time and precious time with our board of directors was spent reviewing and approving SEC filings. As I hope everyone can appreciate, this represented a huge burden for a small company like Cimetrix. In addition to the hard costs that we estimated at approximately $250,000 per year, it is difficult to overstate the amount of energy in terms of management time and attention that went into reviewing and approving not only the financial statements, but the mandatory narratives for these quarterly SEC filings.

Since the introduction of SOX, many public companies have made the decision to go private, and we received a lot of advice over the years that Cimetrix would likewise be much better off as a private company. As you can imagine, however, there are many factors that go into such a decision. We always considered what is best for our shareholders, clients, and employees. Accordingly we were careful and patient in waiting for the right opportunity. From our perspective, that opportunity arose last year, which allowed us to go private without the need for external capital or any dilution to our shareholders. We believe it was an excellent use of the company’s cash to remove the ongoing “tax” of being a public company, which we accomplished in late 2014.

As I reflect back on our first year as a private company, there were a number of highlights in 2015.

• The change in management focus has been remarkable. From the board-level to the daily and weekly operational meetings, the focus is now centered on clients, products, and strategy. How can we better serve our clients? How can we operate more effectively and efficiently?

• Maybe the timing was coincidental, but Cimetrix also completed a major corporate organizational restructuring in early 2015. We involved ten of our key employees in an off-site workshop to map out the type of company we wanted to be going forward. Using an experienced coach and facilitator, we spent time reviewing and reaching agreement on “core” items including our shared vision and values, identification of our core customers, what is our promise to our clients, what is our long term “big hairy audacious goal,” and, equally important, what are the things we should stop doing. We identified the key functions of the company and the people with the best skills and experience to lead those functional areas. The result was a much flatter organization with opportunities for some of our most experienced engineers to assume more management responsibility. It was a very energizing and invigorating process that aligned the entire company on the path forward.

• We also made the commitment to go through our product lines and address all outstanding issues. Over time, the number of product issues that were not urgent or high priority had been slowly building. We made the decision that in order to position the company for faster long-term growth, as well as to reflect our values and brand promise to our clients, we should refresh our current product lines and drive the number of outstanding issues down to zero. This strategy will greatly reduce the long-term costs of maintaining our product lines going forward, as well as further improve the quality and performance of our industry leading product lines. It was wonderful to see the cooperation of our different departments work through the full database of all reported issues and reach resolution. During 2015 we completed new Service Releases for our GEM and GEM300 product lines, which included SECSConnect, CIMConnect, and CIM300, that resolved all reported issues and significantly increased the test coverage for each product. Our Product Management group coordinated the effort to resolve all issues with appropriate stakeholders. Once the backlog of work was clearly identified, our Software Engineering group accepted the challenge and took great pride in doing the work they had wanted to do, but never had had the time, to improve our products and significantly increase the level of automated tests.

• As part of the strategy to improve our customers’ experience using Cimetrix products, we expanded our customer support group into a “Client Training & Support” group with an enhanced staff of senior engineers. Their responsibility is to demonstrate Cimetrix products during the sales cycle, train new clients, and serve as proactive technical liaisons as our clients progress through the critical development cycle. Initial feedback from clients has been outstanding. In particular, I had one new client tell me that in his experience, it is natural for the level of support to fall off a bit after they place an order for a product. However, in the case of Cimetrix, we provided a very high level of attention and support during the sales cycle, and once they placed the PO, they were pleasantly surprised to see that the level of attention and support from Cimetrix actually increased. While they have had problems with other suppliers “over-promising and under-delivering,” their experience with Cimetrix has been overwhelmingly positive, as our software does what we say it will do, and we provide very responsive and passionate support with senior engineering staff.

• We have been at the forefront of the new industry standards for “Interface A,” or its alias “Equipment Data Acquisition (EDA),” for over ten years. When these standards were initially conceived and driven by representatives from Intel and AMD, we thought these new standards made logical sense and would ultimately be adopted by the industry, but we had no idea how long it might take for these standards to be adopted. A large semiconductor foundry in the industry has become the leading user of EDA. Our strategy has been to work closely with this company and the large number of equipment makers that selected Cimetrix’ CIMPortal Plus product to meet the company’s requirements for EDA. While Cimetrix did this facilitation work on our own dime, we believe this investment has paid off handsomely as we’ve helped many of our clients achieve good success in this company's factories, and, as a result, we now have very appreciative clients all over the world that serve as solid references for Cimetrix and our EDA products. In parallel, our Sales and Account Management team has been evangelizing the benefits of EDA to other semiconductor manufacturers. The list of companies now implementing some aspect of EDA has grown to include industry leaders such as Globalfoundaries, Infineon, Inotera, Samsung, Toshiba, and TSMC. The biggest news was Samsung announcing plans for an EDA pilot project in 2016. In a recent briefing to local Korea-based equipment makers, it was reported that some large equipment makers such as Applied Materials and Tokyo Electron developed their EDA solutions in-house, but “most of the rest use Cimetrix products.” To respond to these opportunities, the Cimetrix Sales and Account Management group worked quickly to establish relationships, distribution channels, and local sales and support for Cimetrix products in Taiwan and Korea. While Cimetrix has great partners in Japan, we have learned that each country is different and customers prefer to receive support from companies within their own country, in their native language. Dave Faulkner and Alan Weber logged many miles this year explaining the best practices for EDA and establishing these very important relationships for Cimetrix, which we believe position Cimetrix to sell and support our products more effectively within these markets. In 2016 Cimetrix is scheduled to exhibit in industry trade shows in Korea, China, Taiwan, and Japan that we believe will lead to new clients in these growing markets.

• Lastly, even though we are no longer required to publish SEC filings, we maintain the same high level of internal controls and fiscal discipline. The only difference is we don’t go through the seemingly endless quarterly reviews and narratives. The semiconductor capital equipment market is widely reported to have declined during 2015 and is expected to be flat for 2016. Cimetrix has noticed similar trends among our client base. During 2014, Cimetrix was profitable every quarter with total revenue in the $6 to 7M range with over $500,000 of adjusted EBITDA. For 2015, we continue to operate profitably on a quarterly basis and expect to have similar full-year financial results as 2014. We expect to end the year with close to $2M of cash and, of course, no debt.

Going Forward

Going forward, industry analysts predict a decrease in semiconductor capital equipment spending for 2016. Cimetrix has a number of irons in the fire that we hope will counteract the overall industry trends and enable us to grow next year. We have some major clients in adjacent markets that have the potential to contribute increased revenue. We also hope to get some traction from our efforts to add new clients and grow revenue in the Taiwanese, Korean, and Chinese markets. However, as we have learned over the years, it takes time to develop such new markets, so we are not planning to see large increases in revenue in the immediate future.

By working closely with our clients in semiconductor and adjacent markets, we have identified a number of opportunities for new products. We plan to continue to invest in our current product lines for GEM, EDA, and Equipment Control, as well as look for opportunities to develop new products in conjunction with industry leaders.

If I sound excited about the future for Cimetrix, it is because I am. We have a great team here at Cimetrix and we added a number of solid new team members during 2015. While we have made great progress, we are never satisfied, and will strive for continual improvement as we pursue closer relationships with our clients, improvements in our efficiency and effectiveness, and above all, building great products that help our clients be successful and perform well for those they care about.

I want to thank our clients for the faith and confidence they have placed in Cimetrix’ products and team members, our employees for their passion, dedication and commitment, and our shareholders for their patience that we believe will ultimately be rewarded.♦

In our November EDA-related blog, I covered highlights of the Factory System Infrastructure topic shown in the figure below, and emphasized the need to have a long-term architectural vision to guide the development of a scalable data collection and management environment. Today’s topic completes the picture by summarizing the kind of Manufacturing Applications that can leverage a factory-wide EDA implementation. Unlike infrastructure software alone, these applications are what really provide the ROI for the process engineers and other factory customers of the manufacturing IT department’s efforts, so it is important to understand the scope and requirements of these key applications early in the strategic planning process.

Even though Cimetrix is principally in the business of providing software products that enable equipment suppliers to provide data using EDA technology to the factory application developers that use the information in their production systems, we’ve been involved in this process for many years, and have a good idea of the dominant uses of this data to improve manufacturing Key Performance Indicators (KPIs). So in this blog, I’ll cover a little of the high-level picture of what applications fully leverage EDA data.

First and foremost, it is very easy to connect a basic EDA client to a piece of equipment, upload its metadata, and collect information about that tool’s behavior, so implementing a generic “quick-connect production monitor” independent from the fab-wide data collection system is a very common use for EDA. Moreover, if the model in the tool is compliant to the E164 (EDA Common Metadata) standard, you can make a lot of assumptions about the names of the modules, the wafers, the substrate locations, the process jobs, etc., since all of this information is standardized. As a result, you can quickly get an idea of what the equipment is doing, what recipes it is running, what wafers are being processed, and how well the tool is performing with no custom software whatsoever.

Once this is accomplished, the next step most process and equipment engineers take is to more fully characterize the tool’s behavior, so a very common use of EDA is simply improving equipment and process visibility. By inspecting the equipment model, you can see all the events and parameters that are available to be collected, plot them in Excel or on real-time strip charts, or pass them to other analysis applications.

After the equipment has been characterized, the first major production application most fabs will implement is multivariate fault detection (MVA FDC). This is actually the predominant application of EDA data in the industry to date, because in order to do well-architected fault detection applications, one must “frame” the trace data very carefully. High-speed data collection is usually only required in a small number of specific recipe steps after certain conditions have been established, so you can use EDA’s powerful event-based trace data collection to frame the precise data you want, and pass that on to the multivariate control and fault models.

Of course, once you understand a tool’s behavior and have good fault detection capability, you then start to use EDA data to compare tools across a fleet. You would normally want a set of similar equipment to behave in the same way, but perhaps you have one tool that performs exceptionally well, and you’re not quite sure why…In this case, you do what’s called a “golden run” analysis on that equipment, and compare the key trace variables in one with like variables in similar equipment to see where the differences are, and try to explain why those differences exist. Other names for this class of applications include chamber matching and tool matching.

Another key application that we’re starting to see significant interest in is external sensor integration. Factories are now starting to use EDA to present information collected from independent sensors alongside the information collected directly from the equipment. Sharing a common equipment model across these systems effectively “unifies” that data, so the downstream analysis applications believe the information was collected from a single, integrated source. The EDA metadata model offers an ideal way to accomplish this unification.  

Finally, in many advanced wafer fabs, it is important that substrates do not “sit around” after they’ve been processed. Minimizing inter-process wait times is especially important for some advanced processes, so knowing a priori—the precise moment that a lot is going to complete—is a critical capability so the material handling systems can be scheduled to pick up that material and take it to the next process. EDA provides an ideal way to make these predictions generically for multiple process types using the information that is required in the equipment model.

We’ll address these last two applications—external sensor integration and lot completion estimation—in more detail in later blog postings, but I wanted to get you thinking about these ideas early in the discussion of real EDA usage in semiconductor factories.

There are many more EDA application ideas and examples we could share at this point, from component fingerprinting to wait-time waste analysis to dynamic sampling for wafer-level feedback control to feature extraction for predictive maintenance…but these just scratch the surface of what factory customers will come up with once they experience firsthand the flexibility and power of EDA in their factories. More later as this creative process unfolds!
