Industry News, Trends and Technology, and Standards Updates

The Cimetrix Connectivity Group of PDF Solutions is happy to announce that Cimetrix CIMControlFramework^TM (CCF) version 6.0 is now available for download.

CCF is a software development kit (SDK) that enables users to design and implement a high-quality equipment control solution using provided components for supervisory control, material handling, operator interface, platform and process control, and automation requirements. CCF is built on the reliable Cimetrix connectivity products which provide GEM/GEM300/EDA interface functionality.

We have previously done a series of blog posts on the functionality of CCF. The same great functionality users have come to expect with CCF is still available, but in a cleaner, slicker, easier to use package.

Reorganized directory structure

In versions before CCF 6.0, core CCF packages (packages provided by CCF) were contained in the same directory as sample code and runtime files. This made it more difficult for CCF users to understand what code was required to be customized and what code was basic to CCF. (Note: you can still customize the basic CCF functionality, but it is not required.) In this release, we modified the directory structure to identify more clearly what is core CCF and what is sample or custom code. This is closer to the structure followed by CCF applications. The following diagram shows the new structure:

In addition to clarifying CCF components, the new structure allows us to easily develop samples for additional equipment types. New samples will be added in future versions of CCF.

New WPF framework

Since CCF started providing a Windows Presentation Foundation (WPF) framework, we have received feedback on WPF features user would like added to the framework. Also, our engineers have continued to improve their WPF expertise, which has led to other improvements. CCF 6.0 includes the requested changes and best practice improvements in the new WPF framework. Some of these changes include:

• Simplified hierarchy which makes it easier to understand which objects to inherit from.

• Centralized style elements to allow users to change the look and feel (skin) of the operator interface to meet their needs.
• Enhanced controls library that provides common controls for use in creating equipment control.
• Increased E95 compliance, available with a configurable control panel.
• Accelerated screen creation is possible with the change in hierarchy organization and the enhanced control library.
• Richer set of native WPF screens. In earlier versions, CCF had several native WPF screens, but also had many screens created with WinForms and hosted in WPF. CCF 6.0 has all native WPF screens in the WPF sample operator interface. These screens can be reused, customized, or replaced. (Note: WinForms screens are also still available in CCF 6.0.)

The following image shows the main screen of the WPF operator interface for the CCF atmospheric equipment sample application. Most of the controls on the screen are available for use and customization by CCF developers.

Updated samples

CCF has contained fully functional atmospheric and vacuum sample applications for many years. Over the years, we have improved the functionality for scheduling, simulation, and device interface interaction. However, the samples had always remained the same. With CCF 6.0, the atmospheric and vacuum sample applications were updated to take advantage of the other changes that have been made in CCF. These changes to the samples make them more useful in illustrating the proper use of CCF and providing a better starting point for creating custom applications.

Spring cleaning

CCF was originally released the summer of 2011 making it 10 years-old. Over the years, CCF has had several methods, objects and devices become obsolete. They were not removed from the product for backward compatibility reasons, but they were marked as obsolete. Because CCF 6.0 is a major release, we took the opportunity to do some spring cleaning and remove the obsolete items. CCF is now cleaner and tighter, and using it is much clearer.

Training material and upgrade guide

All the PowerPoint slides, lab documents, and corresponding solutions used for training developers on CCF have been updated for CCF 6.0. We have already successfully used the new training materials with a few customers to help them get started with their equipment control application development.

As part of CCF 6.0, we provide a CCF 5.10 to CCF 6.0 Upgrade Guide that contains detailed instructions on how to migrate applications created using previous versions of CCF to CCF 6.0.

Conclusion

We have been looking forward to the CCF 6.0 release for a long time and are excited for developers to get started using it. We are confident existing users will like the changes and that new users will have a good springboard in getting started with their equipment control application needs. We look forward to working with you and hearing from you.

Near the end of January for almost two decades, the companies that form the Automation Network Dresden (AND) have hosted a gathering of semiconductor automation professionals in the picturesque setting of Dresden, Germany. The chill of winter during this event has always been in stark contrast to the warmth of the reception the speakers and participants enjoy at this event. The big question this year was “how could the organizers possibly maintain this tradition amid the COVID-19 pandemic and its travel restrictions?"

Automation people being a creative bunch, they responded by offering a series of free, half-day “digital events” spread across the first four months of the year, and each hosted by one of the AND member companies: SYSTEMA, Fabmatics, XENON, and Kontron AIS. The first two sessions are now in the record books, and as a participant in both, I can attest that no momentum or value has been lost. The only exception is the lack of the forum’s famous evening event, which will undoubtedly return next year when the virus is behind us.

The first session of the year was hosted by SYSTEMA on January 28 with the theme of Datafication and Automation: The new normal for semiconductor manufacturing. I was privileged to among the invited speakers, and shared the agenda with Manfred Austen of SYSTEMA (always a hard act to follow!), Jean-Marc Philippe of ST/Micro Singapore, Axel Wogawa of SYSTEMA, and Klaus Kleilein of Fabmatics.

In this context, I chose the topic of semiconductor backend automation, and you can download my presentation “Wafer Fab Best Practices for Backend Automation”. Key takeaways from this presentation include the industry drivers for higher levels of backend automation, the unique challenges this poses when compared to wafer fab automation (see the figure highlighting multiple material transformations below), the role that industry standards in many categories will play in this process, and last but not least, the importance of defining explicit integration message sequences between all the equipment and the factory systems that bring them together into fully automated operations. This latter insight was one of the key enablers for the wafer fab transition from 200mm to 300mm, and the concept equally applies in the backend.

The second event in the series was hosted by Fabmatics on February 25, 2021, with the enticing theme of Forever Young: Automation Makeover Rejuvenates Golden Age Fabs. It featured speakers from Bosch, Nexperia, Cohu, and SYSTEMA.

The next event will be hosted by Xenon on March 25, 2021 with the theme Digitalization Meets Mechanical Engineering, and the final event hosted by Kontron AIS on April 29, 2021 (theme still TBD – stay tuned).

In December, 2020, Cimetrix Incorporated was honored as a Utah Top Workplace by the Salt Lake Tribune.

The Salt Lake Tribune partnered with Philadephia-based Energage to rank the Top Workplaces in Utah. Energage surveyed workers from over 1,300 Utah companies on a variety of topics to rate their workplace. Out of this pool, just 100 companies were selected as Utah Top Workplaces. Companies were then placed in categories by number of employees. Cimetrix was ranked 12^th out of the 45 finalist companies in the “small business category”.

At Cimetrix, we believe the key to a successful business is having a values based culture that focuses on ensuring our customer’s success and having everyone in alignment. Employees need to be doing a job they love, working on something they are passionate about and being rewarded for contributing to the company’s success.

We are honored that Cimetrix employees feel so passionate about the culture we’ve built that we were selected at a Utah Top Workplace for 2020.

While we were recently acquired and will now operate as the Cimetrix Connectivity Group within PDF Solutions, that doesn’t change our commitment to employees, culture and the core values that have made us successful. Employees drive our success and we look forward to a 2021 filled with new opportunities and potential.

Background and Audience

Over the past several years, I have written numerous blog postings heralding the benefits of the SEMI Equipment Data Acquisition (EDA, also known as Interface A) standards, promoting their adoption by 300mm wafer fabs around the world, explaining how to develop robust purchase specs to ensure the interfaces delivered by the equipment suppliers meet the fab customers’ expectations, describing how the various components of the standards work together and the importance of the embedded equipment model, and finally explaining how to run compliance and performance tests on an EDA interface to validate its fitness for production use. The target audience for most of these postings has been the factory users, for they are the ones who increasingly depend on detailed equipment and process data to profitably run their enterprises.

By contrast, this posting is aimed at the equipment suppliers who are looking to increase the value of their product families by augmenting their hardware offerings with software capabilities that only they are uniquely qualified to provide.

This is not a new idea. Several major equipment suppliers have offered so-called “Equipment Engineering Systems (EES)” products as companions for their equipment over the years, providing applications like Fault Detection and Classification (FDC), production monitoring, maintenance management, local repositories for diagnostics and field support, and other capabilities that leveraged deep domain knowledge of the equipment. However, these systems necessarily relied on private interfaces to the equipment for their data, such as an additional network connection, direct access to the file system, or other mechanisms. And from the fab’s perspective, these constituted yet another piece of infrastructure to maintain.

Now there’s EDA: a key enabler for value-added equipment applications

Since the SEMI EDA standards are inherently multi-client, a single EDA interface can support not only the factory information and control systems that depend on equipment data, it can also provide whatever information a supplier-specific application may need as long this data is represented in the equipment metadata model. Since that model is designed by the equipment suppliers as a fundamental component of the EDA interface, they can choose to put as much information in these model as they want, possibly well beyond that required by the fab customers’ purchase specifications. In fact, these models could be used to implement the diagnostic logging capability that suppliers usually build into their equipment for their own use, but without requiring custom software to read and interpret that information. See the figure below for an example of such a configuration.

The EDA standards also include a provision for “built-in DCPs” (DCP = Data Collection Plan) which can be shipped with the equipment and protected from accidental deletion at the factory site. These DCPs could be crafted by the equipment supplier to directly feed whatever value-added applications the supplier chose to develop, whether these resided on a computer local to the equipment in the fab, on portable computers used by field service engineers to diagnose problems, or on remote cloud-based systems allowed to connect via secure EDA-defined URLs. This flexibility opens up a wide range of application types, from those that embed equipment-specific algorithms to generic Machine Learning frameworks… the possibilities are endless.

What all these approaches have in common is a standard EDA client capability that can establish a session with the equipment, activate Data Collection Plans, and receive the ensuing Data Reports. The EDAConnecter within the Cimetrix Sapience platform provides all these features and more in a lightweight set of .NET libraries which can be deployed wherever they are needed to consume EDA data.

Conclusion

More and more semiconductor factories are requiring EDA interfaces with their new equipment purchases with highly prescribed equipment models and demanding performance criteria. From the equipment supplier’s perspective, these requirements have been viewed as a source of additional cost, with all the benefits accruing to the factory customers. But it doesn’t have to be that way…

Why not take advantage of this interface to offer additional value using a standards-based approach? This just might be an idea whose time has finally come. If you agree, give us a call – we can help you make it happen!

Today’s blog posting highlights the latest and most recent activity with the Cimetrix Book Club. Our employees constantly strive to develop their skills, share information, and keep up to date with the industry. Part of this effort includes an employee book club that involves many of our team members each month, and from time to time we cover some of their favorites here on our blog!

Today's book is titled "The Art of Unit Testing" by Roy Osherove. The book review is by Westley Kirkham, a Quality Engineer based in Salt Lake City, UT, USA.

“The Art of Unit Testing” guides the reader step by step from writing the first simple tests to developing robust test sets that are trustworthy, maintainable and readable.

In the first section, Osherove explains what a unit test is, the properties of good unit tests, and why they are so important. The lion's share is dedicated to the nitty-gritty of writing and maintaining unit tests specifically, and testing suites generally. The first part of the section goes in depth to show how Mocks, Stubs and Isolation frameworks are used to test your code. The last section discusses how to deal with resistance to change from co-workers and management if you're trying to introduce Test-Driven Development or Agile methodologies, as well as how to deal with legacy code. Osherove also shares his insights on what tools he believes are the best aids in unit testing. ReSharper is one of his favorites, but he also reviews Nsubstitute, Moq, CodeRush and others.

One section that stood out to our team was Osherove's three pillars of a good unit test—trustworthiness, maintainability, and readability.

Trustworthy tests are up-to-date, simple and correct. There are no duplicate tests, and they do not test any old functionality or functionality that has been removed. The unit test only tests one item and doesn't conflict with other tests. The bugs the test finds are actual bugs in the code, and not bugs in the test.

Maintainable tests are flexible, and don't break with each minor change to the product. The tests are isolated. They are not over-specified and they are parameterized.

Readable tests are easy to understand and do not require the developer or tester who comes after you to spend extra time understanding what you've written. The test names are descriptive, and the asserts are meaningful. Any failures or issues caught will lead the developer in the right direction.

These three pillars should apply to all that we write, not just tests.

At Cimetrix, much of what Osherove teaches is already integrated into our engineering culture. As part of our implementation of Agile, developers write unit tests to verify that the functionality they have coded is correct. It is then reviewed by another developer and a member of the QE team to ensure that common use cases and important edge cases are covered and that the functionality is complete. All code must follow naming conventions and styles verified through ReSharper. For all of our products, unit tests are run on each build, and integration tests are run nightly.

Osherove's lessons on unit testing implementation, testing suite organization, and test-driven development integration are simple and practical. This book would benefit any team looking to improve the fidelity of its software products and the efficiency of its engineers.
