Yes, that is correct! Because electricity travels through a wire at the approximate speed of 1 nanosecond per foot! Chuck Original Message From: cm...@zeusprune.ca To: neonixie-l@googlegroups.com Subject: Re: [neonixie-l] Re: How ICs are made - the inside track... Date: Wed, 25 Jan

1985 was my 'golden year' as well. Started work at TRW doing 2 micron CMOS design for the Milstar program. Several of those birds are still in orbit, and with several of the ICs I worked on. That old technology sure is rugged. At some point, the process technology: - Doesn't result in

In 1985, shortly after, I got out of school, they just broke the 1 micron barrier. I think wafers were ~5" (~130mm). >From the few people I've known, that were in the semi business, they change "mask sets" for parts routinely, for an existing part. This is due to keeping up to the current

I started in PCB manufacture with 'punch and crunch' double sided PCBs and ended up maintaining 24 layer 4 thou track and gap equipment which was cutting edge at the time. Spent 11 1/2 years in CMP going from 64nm on 200mm wafers to 14nm on 300mm wafers. Now 7nm on 400mm wafers are on the

I just finished reading the article "The Molten Tin Solution" by Rachel Courtland in IEE Spectrum which explains some of the EUV chip-printing technology so this description was a nice view from another side of the complexities of producing ic's, especially as they talked about the problem

Thanks for posting. To put things into perspective, I was working on a 40nm project (the above posting mentions 40-40nm process technology) 10 years ago, and we actually switched it to 32nm. And that was also 10 years ago. A lot has changed since then. You wouldn't believe the things we did to
