My patents are in the chemistry of semiconductor lithography. It's amazing to see how far the industry has come in just a few years. The speeds are starting to deviate from Moore's Law (chip speed doubles every 18 months,) but the memory sector is just mind numbing. Memory chips are now based on 50 nanometer technology!! When I left the industry, they were at 193nm in some fabs, and sub-100nm was not even on the drawing board.

Mike, again, I'm sorry your introduction to ART could not have been on more positive terms. I do not know the full story behind the relationship you and Doug (nor do I care to know.) Doug has been very helpful for us newbs and always willing to help. He really is a good guy that cares about the preservation of vacuum tube technology. I wish you two the best of luck in sorting out your differences.......Colin
