Dear Misen:

I do know of one production semiconductor process that uses 200+ scans right off the top of my head, that of making VCSELs. They need a 30-60 pairs of alternating materials to do the mirrors at the top. Each layer takes two scans. Granted it is a special structure, but the results are well worth it for very high speed high data rate comm (>1TB/s). And yes they are SESP at a relatively wide process. They usually have the drive logic adjacent to the VCSEL. Long term they are looking at it to do interchip comm.

Pete
