How do you know the chip as fabbed conforms to the final tape out?
- signa11 9y agoumm, i am unaware if it is possible for manufacturing companies to make changes like these to a design handed out. can you please explain how ?
- pjc50 9y agoThe design as presented to the fab is usually "GDSII" format, which is a huge list of polygons on various layers. Manufacturing companies usually have to run this through preprocessing in order to make the interference lithography work properly. In the end, they produce a bunch of IC masks, and it's always possible to ""manually"" (with expensive tools) cut another hole in the mask.
