In the first blog of this series, Clare Liu of Cimetrix China made the compelling case for choosing a commercial software platform for implementing the equipment side of the EDA (Equipment Data Acquisition) standards interface rather than developing the entire solution in-house.
Whenever this “make vs. buy” decision is discussed, however, the following question inevitably arises: “If we choose a standard product for this, how can we differentiate the capabilities of our equipment and its data collection capability from our competitors?” It’s a great question which deserves a well-reasoned answer.
Platform Choice and System Architecture
Most advanced fabs use EDA to feed their on-line FDC (Fault Detection and Classification) applications, which are now considered “mission-critical.” This means if the FDC application is down for any reason, the equipment is considered down as well. It is therefore important to choose a computing platform for the EDA interface that is highly reliable and has enough processing “headroom” to support the high bandwidth requirements of these demanding, on-line production applications. Moreover, this platform should not be shared by other equipment communications, control, or support functions, since these may adversely impact the processing power available for the EDA interface.
Surprisingly, this approach is not universally adopted, and has been a source of problems for some suppliers, so it is an area of potential differentiation.
Adherence to Latest Standards
The automation requirements for the most advanced fabs call for the latest versions (Freeze II) of all the standards in the EDA suite, including the EDA Common Metadata (E164) standard. Dealing with older versions of the standard in the factory systems creates unnecessary work and complexity for the fab’s automation staff, so it is best to implement the latest versions from the outset. The Cimetrix CIMPortal Plus product makes this a straightforward process using the model development and configuration tools in its SDK (Software Development Kit), so there is absolutely no cost penalty for providing the latest generation of standards in your interface.
It takes time and effort for equipment suppliers with older versions of the standards to upgrade their existing implementations, so this, too, is an opportunity for differentiation.
Equipment Metadata Model Content
This is probably the area with the largest potential for competitive differentiation, because it dictates what a factory customer will ultimately be able to do with the interface. If an equipment component, parameter, event, or exception condition is not represented in the equipment model as implemented in the E120 (Common Equipment Model) and E125 (Equipment Self-Description), and E164 (EDA Common Metadata) standards, the data related to that element cannot be collected. In effect, the metadata model IS the data collection “contract” between the equipment supplier and the fab customer. 
This is why the most advanced fabs have been far more explicit in their automation purchase specifications with respect to equipment model content, going so far as to specify the level of detailed information they want to collect about process performance, equipment behavior, internal control parameters, setpoints and real-time response of common mechanisms like material handling, vacuum system performance, power generation, consumables usage, and the like. This level of visibility into equipment operation is becoming increasingly important to achieve the required yield and productivity KPIs (Key Performance Indicators) for fab at all technology nodes.
The argument about “who owns this level of information about equipment behavior” notwithstanding, providing the detailed information the fabs want in a structure that makes it easy to find and access is a true source of differentiation.
Self-Monitoring Capability
If you really want to set your equipment apart from your competitors, consider going well beyond simply providing access to the level of information needed to monitor equipment and process behavior and include “built-in” Data Collection Plans (DCPs) that save your customers the effort of figuring out what data should be collected and analyzed to accomplish this. Your product and reliability engineering teams probably already know what the most prevalent failure mechanisms are and how to catch them before they cause a problem… why not provide this knowledge in a form that makes it easy to deploy?
A few visionary suppliers are starting to talk about “self-diagnosing” and “self-healing" equipment… but it will be a small and exclusive group for a while – join them.
Readiness for Factory Acceptance
Before the fab’s automation team can fully integrate a new piece of equipment, it must follow a rigorous acceptance process that includes a comprehensive set of interface tests for standards compliance, performance, and reliability. This process is vital because solid data collection capability is fundamental for rapid process qualification and yield ramp that shorten a new factory’s “time to money.” If you know what acceptance tests and related software tools the fab will use (which is now explicit in the latest EDA purchase specifications), you can purchase the same software tools, perform and document the results of these same tests before shipping the equipment.
This will undoubtedly speed up the acceptance process, and your customers will thank you for the effort you took to put yourself in their shoes. Incidentally, this usually means the final invoice for the equipment will be paid sooner, which is always a good thing.
In Conclusion
In this posting, we have only scratched the surface regarding the sources of competitive differentiation. As you can see, choosing a commercial platform enables this far more readily than the in-house alternative, because it allows your development team to focus on the topics above rather than worrying about compliance to the standards.

IPC Apex Expo is one of the largest gathering of professionals from the printed circuit board and electronics manufacturing industry (EMS). Attendees and exhibitors come from around the world to participate in the expo, the technical conferences and Standards Development meetings. This is the third year in a row that Cimetrix has exhibited at the IPC Apex conference.
Cimetrix features the latest in Smart Factory and Equipment Connectivity technology. For the show this year, we chose to upgrade our booth space, allowing us to have more meeting room within the booth as well as several prominent demo stations in each corner. We also featured a popular Virtual Reality station in our booth. We brought a great team of ten to the show this year to staff the booth, give demo’s and greet the many attendees who stopped by throughout the 3 day expo.
It's time to meet the folks that keep Cimetrix running - our Front Office team! Meet Devin Stone, a Cimetrix 
IPC Apex is next week, and we hope to see you in Sunny San Diego! This year we’ve upgraded our booth and you can find us exhibiting at #2801. We will be participating in the exciting Passport to Prizes program so be sure to look us up so you are eligible for some excellent giveaways!
Thank you for the trust and confidence you continue to place in Cimetrix. 2018 was an exciting year as we made great progress executing our strategy for long-term profitable growth. Cimetrix posted another year of strong growth as total 2018 revenues increased over 20% year-over-year. Since going private in 2015, Cimetrix has grown at a 20% CAGR (compound annual growth rate). In addition, Cimetrix posted its 9th consecutive year of profitability, which allowed us to further strengthen our cash position and balance sheet. Having no debt and a strong balance sheet gives us the ability to execute our longer-term growth initiatives and withstand short-term market disruptions.
It's getting close to the end of 2018 and we thought it was a good time to look back over our year and think about the many things Cimetrix has done. We are really proud of our team, which spans the globe, their hard work and accomplishments throughout the year. 
A small engineering company hired a brand-new engineer from a competitor. He was introduced by management as being “dynamic and creative” and they would see “where he would fit” in the company. The engineer walked around, asked questions, and began to learn about the different projects under consideration and what he might be interested in. During his first month with the company, two of his peers quit. When asked about their reasons for leaving in the exit interview, both felt like that management had hired the new engineer to take their place. In the absence of solid communication from management, two good employees made incorrect assumptions and moved on. It was never management’s intention to replace anyone and the feedback surprised them. Additionally, they were surprised by the fact that the employees didn’t feel comfortable about coming to management and asking about the role of the new engineer. This situation provided a valuable lesson about the importance of open and vibrant communication.
