E beam lithography in credibly difficult. Recommend chapter 13 in "Principles of Lithography" https://spie.org/Publications/Book/2525392?SSO=1 . My opinions is that this whole comm…

More insight from me. First, the structure. TSMC will have tool owners who manage the tool on their side. The tool suppliers will have engineers who maintain the tools from their s…

Can’t tell you the exact details but you should be able to find details from the patents, papers, and tech talks from ASML.

Definitely two types of software here. Everything about that post is spot on. Internal software is messy. Testing is also messy. Lots of things need to be automated. End of the day…

Can't talk about that :)

I am not an expert in this area. Most of it is physics simulations. An example I know of is that we use feed forward control to make sure layers are aligned and printed with nanome…

I work in the industry and have worked in a fab. Here is some insight. We are taught that fabs are not treated as factories but as hazardous chemical storage plants. On top of that…
