As with most things in life, having an understanding of how things are done and what is expected will help determine the success and rate of success.  This definitely pertains to getting your product through SEMI S2, the safety guideline for semiconductor manufacturing equipment. and why our CEO, Steve Barcik Amstel  finds it imperative to lay the foundation for a quick and successful experience with SEMI S2.  This is our continuing video training series on SEMI S2.


(Link to video also available here:


In today’s video, Steve talks about the evaluation process, which is Section 8 from the standard. He walks you through what the standard says about the evaluation process itself.


What there is to do is to evaluate equipment line by line to the sections of SEMI S2 and that really begins in Section 9 and goes through all the way until Section 27. Section 8 talks about how to evaluate line by line to those other sections.

Section 8 starts off with doing observation, testing, collecting information and data looking at that data as it pertains to each individual section. Then with the support of the engineering team at your company and your documentation, drawings and the test equipment that we’ve brought, we will come to a conclusion on each specific line item of the standard. Now sometimes that conclusion will be affirmative, but we have some questions and we will verify that with you. And then sometimes that determination will be negative. Again, we will ask you questions that will verify that and change the response, to affirmative.



SEMI S2 provides us two different ways to say something conforms. It may conform specifically to the section; meaning in that individual case the equipment directly and precisely meets the requirements of that section. Alternatively, we can say that it conforms to a performance standard or that it conforms to the performance goal of that section, which is a higher more in-depth requirement…meaning that we will have to do more to get there. Generally, it is best just to conform directly to each section but we can also do the latter, which works as well.



Then from this place there are other options for us to pick in approving your equipment. A bit more on a finding of your equipment meeting a performance goal of a standard or a section of SEMI S2 would also include us doing a risk assessment of the outcome. So, let’s say you had some performance based achievable conformance, we would also do a risk assessment to verify that the risk was low or very low for that section.



The other option for us to choose for conformance of a section would be “does not conform”. This means that the equipment itself or the documentation or other ancillary requirements are not met and typically during an exit interview with you and your team, we will go over each of those to say here is the finding and we think that it doesn’t conform and give you an opportunity to provide us more data or provide options or best practices to then have the equipment conform. Sometimes a non-conformance might be based on not having enough information. Maybe we are looking for a suitability for use for a subsystem and maybe we don’t have test data on the overheat process of a piece of equipment or maybe you’re not complete with the functional safety evaluation of another section. We include all of this in the report when we do report those findings and summarize those. For each of those non-conformances as well, we will do a risk assessment and determine what level of risk is associated with that non-conformance.
