Track Material More Intelligently Using These Factory Automation Principles

Posted by Rich Kingsford; Project Manager, CCF Services on Oct 21, 2020 11:05:00 AM

Tracking material is essential.

Tracking material is essential, especially when you're trying to mitigate risks and diagnose malfunctions. I was impressed at a recent project where our CCF Services’ customer envisioned some colorful and contextual operator interface (OI) controls. Let's explore them.

Colors and icons to emphasize info

We've always used colors to denote the status of material in the equipment, e.g. Needs Processing, In Process, Processed, etc. But this customer used a color legend and a wider range of colors to help the operator more easily track material in realtime. We used color vibrancy (e.g. bright colors or dull colors) to draw attention or soften attention, depending on how important the datum.

ccfblog3.1.1"What about color blindness?"

  • While our customer chose not to bother with color blindness, other customers prefer to use icons or patterned backgrounds in their schema, to aid those who are colorblind.
  • We also display the state as a text string, making it even harder to misinterpret, while maintaining the visual.

"What about E95 standards and other important factory standards?"

  • Our standards experts, Brian, reminded us that there are no constraints in the color department

 

Don't bother me with a small details

Our customer wanted to regularly demonstrate our progress to their directors and executives. But these audience members weren't very technical. Khoi, our OI designer, created a pretty cool bird's-eye view of the equipment with its numerous material locations. We used colors in the bird's eye view to help the non-technical folks understand where material was at in the equipment and the condition of the material. (We joked about adding disco lights too. And Easter eggs.)

Mirroring physical location

We’ve always visually grouped similar components together, but we took physical layout to the next level on this project by turning some of our tables sideways to simulate the physical tool more accurately (a boat tool). We also made a few pyramids to simulate the locations of the physical components. This makes it easier to visualize how the different parts of the machine work together. Matching the real-world positions, one can more easily anticipate the material flow. Additionally, we displayed all the information on a single screen so the user no longer has to scroll horizontally or vertically to see the various components.

ccfblog3.1.2

 

Anticipating operator needs (and possible blunders)

When designing the OI for this project, we wanted to explore ways we could anticipate the operator’s typical and atypical actions (sometimes called happy path and edge cases). If we can understand the operator’s intentions, we can build in mechanisms that prevent risk of damage or getting stuck. We can also build in contingency mechanisms, such as errors, that will make malfunctions easier to diagnose. An example of a prevention mechanism we used on this project was context-sensitive buttons (e.g. disabled under some circumstances) so as to prevent the user from erroneously clicking a control. We also built additional confirmation mechanisms (e.g. a confirmation before discarding a manual change).

Conclusion

We value these 10 Usability Heuristics for User Interface Design as well as other widely accepted usability principles. Intelligent usability mechanisms are usually simple to implement, but often get ignored. A little extra attention in this department can save many hours and even days of debugging time. A more usable Operator Interface is also more likely to impress your stakeholders!

Semiconductor Backend Processes: Tracking Process Execution

Posted by Alan Weber: Vice President, New Product Innovations on Sep 30, 2020 11:45:00 AM

Background

semi-e157-pic1

Previous blog posting in this series have discussed the rationale for using SEMI’s GEM, GEM 300, and related automation standards in semiconductor backend factories, and pointed out that the specific adaptations required for the various backend equipment types are one of the focus areas for the SEMI Advanced Backend Factory Integration (ABFI) Task Force. In this posting, I will deal specifically with the benefits that can be realized by using the E157 Process Module Tracking standard in a backend factory context.

Since none of the backend material transformations are implemented in what front end experts would consider a “process chamber,” this may seem like an unlikely fit. Moreover, the velocity of backend processes seems contrary with the typical front end recipe execution paradigm. Finally, the lack of distinct substrate locations for some of the processes makes it difficult to know precisely when the process begins and ends for the affected material in some cases.

Regardless of these challenges, the requirements for single device traceability that include knowing the exact process conditions that a device was exposed to at every moment in its manufacturing life cycle (including the backend) argue for use of this standard wherever possible.Since none of the backend material transformations are implemented in what front end experts would consider a “process chamber,” this may seem like an unlikely fit. Moreover, the velocity of backend processes seems contrary with the typical front end recipe execution paradigm. Finally, the lack of distinct substrate locations for some of the processes makes it difficult to know precisely when the process begins and ends for the affected material.

SEMI E157 – Process Module Tracking

The purpose of SEMI E157 is “to define a standard equipment capability to report process-related data to the factory system… the activities of a processing location (i.e., process module) that are related to the execution of a recipe.” The standard further states that “the collection of process data during recipe execution is important to today’s semiconductor factories to support various applications that help optimize equipment processes, finished product quality, yield, and overall factory performance.”

These requirements are now every bit as important for backend factories as they are for the front end, so it is useful to understand how E157 can be effectively applied.

First of all, the E157 Module Process State Model is fairly simple, having only 4 states (three of which are “base states” with no sub-states) and 7 state transition events, shown in the diagram below.

E157-pic1This model represents the state of that portion (or portions) of a unit of equipment that executes a recipe to transform whatever material is present in that part of the equipment. In front end equipment, the chambers are relatively distinct, and usually process a small number of substrates (often one) at a time. By contrast, backend processes cover a broad spectrum of material types, from single wafers to strips (or lead frames) of multiple die to individual packages. The material flow characteristics also vary, from discrete (i.e., single workpieces) to batch to continuous. Moreover, the production rates and material volumes for these processes range from perhaps 90 wafers per hour to thousands of packages per hour… With these challenges, it is no wonder that the pace of automation for these facilities has lagged that of the front end.

How is the E157 Standard Used?

From the equipment’s perspective, every time the process module changes state according to the model above, the equipment sends the corresponding state transition event to the factory host computer. This is done using the SECS-II S6, F11 Event Report message with an event name exactly prescribed by the E157 standard.

The event report should also include whatever “context information” from the equipment that the factory applications need to analyze the equipment’s performance and behavior. For some backend processes, this might be lot ID, process job ID, recipe name, control settings, and current parameter values for important process variables. For others, it might be cumulative usage counts for fixtures with limited lifetimes, current levels of consumables used in the process, or configuration parameters for equipment with a range of setup possibilities. To further complicate matters, some of this information is common across most processes, some of it is process-specific, but some of it may actually be vendor-specific. It all depends on how the factory operates.

Finally, when used in conjunction with event timing information from other required standards (e.g., E90 Substrate Management), E157 data can help identify potential productivity issues, say, when there is an unexpected delay between material arrival (from E90) and recipe start (E157).

How Might E157 be Adapted for Backend Equipment?

As noted above, some equipment types process a stream of material continuously. In these situations, for a given lot, multiple substrates may be processed at the same time in a continuous flow (say, on a conveyor through an oven) until the lot is complete. For these types of equipment, E157 cannot be directly applied because it is chamber oriented, and you don’t get much useful information if you use the entire lot as the execution starting and completing events.

However, if you apply the same state model to the material (substrate, strip/lead frame, carrier, etc.) being processed rather than the equipment component, the collection events defined by E157 can be implemented when a unit of that material changes state. Specifically, the equipment can report the same collection events (ExecutionStarted, StepStarted, StepCompleted, ExecutionCompleted, StepFailed and ExecutionFailed) when execution on a substrate changes state, including when a step is started and completed. The meaning of a “step” would still be interpreted and designed by the equipment supplier. Associating these E157 collection events with a new “substrateID” data variable rather than a chamber enables the factory user to track the material state for each substrate going through the equipment.

Which Backend Equipment Types Should Implement E157?

Even though backend metrology, inspection, and test equipment may run recipes to perform their tasks, since no material transformation takes place, the state transition events and related context are far less important than the measurement and inspection results that these equipment types generate.
For the rest of the backend processes, the relative priorities for implementing E157 are the following:

High – die attach, wire bonding, dicing/sawing/singulation

Medium – backside grinding, polishing, plating, annealing molding, trim and form

Low – wafer mounting, die glue curing, deflashing, laser marking, tie bar cut, baking, burn-in

One category of equipment we have not mentioned is custom assembly equipment that can vary greatly by the end product form factor. The use of E157 in this equipment will depend entirely on the process complexity and sources of variability that must be tracked. However, it is safe to assume that for all but the simplest of processes, E157 will likely play a useful role.

Conclusion

E157 is a prime example of an exceptionally simple and well-written standard built on top of GEM technology that is easy to implement and provides a lot of end user value. The SEMI ABFI task force is now evaluating the specific adaptation of E157 for various backend equipment types and welcomes your contribution to that process.

Building a Panel Tool for a Customer using CCF

Posted by Rich Kingsford; Project Manager, CCF Services on Aug 20, 2020 11:38:00 AM

Hi folks! We in the CCF (CIMControlFramework) Services Team love training/consulting on CCF implementations and building custom software for our customers. We’re especially thrilled when we can help our customers ship new equipment and subsequently hear that the equipment successfully ran thousands millions of cycles without issues.

Recently, we enjoyed helping one of our customers build a tool that processes non-wafer substrates. The tool control system included some typical components such as Rorze Hardware Drivers, Light Tower drivers, and a Load Port E84 IO Control, but had some more unique capabilities as well. In this posting we will explore some of the challenges posed and advantages realized from these special capabilities. Before we dive in, please allow me to give a shout out to John Last, our Senior Software Engineer who designed and built most of these capabilities.

Building-panel-tool-1

Process Module Operation Screen

Rather than simply logging data points, our customer wanted a visual representation of temperature over time (minutes). We displayed the categorized variables and their values in tables as well, but the graph updating in real time made it much easier for the operator to visualize the patterns and identify risk events and their sources. The graphing feature needed to be active whether or not the process module operation screen was being displayed. Moreover, It had to handle 3 different step types (Ramp, Dwell and Cool).

Calculating the Y-Axis range for this display presented an additional interesting challenge. The minimum and maximum values were determined by searching all recipe steps and selecting the lowest and highest value setpoints, then subtracting a fixed number from the lowest to get the Y-Axis minimum value and adding a fixed number to the highest value to get the Y-Axis maximum value. The figure below shows how the expected process data should look compared to the observed process data. This allows the operator to see what the equipment is expected to do compared with its actual behavior.

Building-panel-tool-2

Partial FOUP grouping to create a single batch

Our customer required the capability to group multiple partial FOUPs into a single batch. This is especially useful in scenarios where partially filled FOUPs would be used—say, in R&D environments. In other words, we needed to support scenarios where the number of FOUPs needed for processing a batch exceeded the number of load ports. This required us to create Control Jobs with a MtrlOutSpec containing a valid SourceMap with an empty DestinationMap. We relied on SEMI E94’s concept of “Late Announcement of Output FOUP” to specify the input FOUP but not the output FOUP. This allows the scheduler to say, “We know the substrate will go to a different slot, but we won’t tell you which slot until later.”

E90 substrate reading in the Panel solution

As with most tools, each of the substrates has an ID, and this ID must be read and reported to the host. In this case, our host had to verify that the expected ID matched the actual ID. On a successful match, the equipment would then continue the job. If it failed, however, the host would be notified and decide whether to proceed or change something. Capabilities like these maximize throughput and mitigate risks to equipment safety side and production scrap.

Different Panel Types

This machine was required to deal with panels having multiple thicknesses and possible warpage. Therefore we needed to provide a method for an operator, the recipe, and the host to specify the panel type to be processed. None of the variations of panel types were known ahead of time, so we needed methods that handled additional panel types without having to make code changes after the equipment was deployed in production.

The tool also required different substrate mapping parameters for each panel type. Because panel type was specified in the process program referenced in the Process Job, the panel type was not known when the FOUP arrived at the load port. To handle this situation, we customized a standard factory automation SECS II message to communicate the panel type from the host to the tool on arrival of the FOUP.

Conclusion

This equipment was built on an extremely aggressive timeline by a very small team. I was particularly impressed by the team’s ability to grasp the end customer’s requests and creatively explore alternative ways to solve the never-before-seen challenges. In summary: no drama; a few delays; even fewer verbal altercations; just a little frustration; only a little scope creep; and most important, a satisfied factory customer. We all cheered when our customer shipped the tool in 2020.

Summer 2020 North America DDA Task Force Report

Posted by Brian Rubow: Director of Solutions Engineering on Aug 12, 2020 10:45:00 AM

Background

The SEMI North America Diagnostic Data Acquisition (DDA) task force is part of the North America Information and Control Committee (I&CC or NA I&CC). This year the meeting that is normally held in conjunction with SEMICON West was held on Tuesday, July 14, 2020, and continued its activities in developing important SEMI standards. As co-leader of the NA DDA task force, I offer this blog as a summary of the current task force activities.

Freeze 3 Status

The primary responsibility of the DDA task force is the suite of Equipment Data Acquisition (EDA) standards, sometimes referred to as “Interface A.” Currently there are two version sets of EDA standards known as “Freeze 1” and “Freeze 2” which are both based on SOAP/XML over HTTP. The current activities are focused on defining the next EDA set (already designated “Freeze 3”) which is based on a binary protocol gRPC over HTTP. This technology, along with a number of other changes, promises to dramatically increase data collection throughput capacity.

Here is what has been completed so far:

Summer 2020 North America ABFI Task Force Report

Posted by Brian Rubow: Director of Solutions Engineering on Aug 5, 2020 11:00:00 AM

Background

The SEMI North America Advanced Backend Factory Integration (ABFI) task force is part of the North America Information and Control Committee (I&CC or NA I&CC). Normally this task force meets every July in San Francisco as part of SEMICON West. However, this year the technical committee meetings are spread out over several weeks and do not coincide directly with the exhibition. Additionally, the I&CC did not meet at all because SEMI regulations do not currently allow TC Chapter (Committee) voting in virtual meetings. That will hopefully change later this year, but for now delays SEMI standards development.

Regardless of these challenges, the ABFI task force did meet on Monday July 13, 2020 and continues to develop SEMI standards. I am co-leader of the NA ABFI task force along with Dave Huntley of PDF Solutions. This blog is a summary of the current task force activities.

Ballot 6648 to update to the SEMI E142 (Specification for Substrate Mapping) specification has passed initial voting and is recommended to be accepted and published. This ballot significantly enhances the amount of traceability data that may be embedded within wafer maps.

Additional Wafer Map Activity

Because wafer maps will potentially be much larger with additional traceability data, they could be too large for the messages currently defined in the E142.2 standard. A new activity has been started to modify wafer map usage further and to allow Stream 21 messages to be used for wafer map transfer. The stream 21 message in the SECS-II standard can be used to transfer very large items through a GEM interface.

SEMI Standard Usage Matrix for Backend

The ABFI task force is also defining a matrix that specifies which standards beyond GEM (E30), SECS-II (E5), HSMS (E37) and Substrate Mapping (E142) should be used for backend automation, and under what conditions they should be used. This includes consideration of the full suite of GEM 300 standards and other standards that all GEM interfaces should consider, such as SEDD (E172) and SMN (E173).
