Something like that isn't totally crazy. Just mostly. :) A friend ran a lab course at the University of Colorado Boulder teaching undergraduates how to make silicon chips. IBM donated most of the gear when they decommissioned a 2 inch fab line. Yes, that was many years ago. One of his great stories was the day a guy wandered into the lab looking for a job. He used to run a fab line for HP and had decided to take a year off to go back to school and get a masters. Needless to say, he was hired. That was a good year. I assume the number of crystal lines is pretty small so getting a whole setup as a donation seems unlikely. I could imagine being able to "rent" a factory for long enough to run a course if a company is going out of business or something like that. It would probably be too expensive but stranger things have happened. If a class like that ever happened, I wonder what fraction of the class would be curious time-nuts rather than serious students planning to get a job building crystals. Just a set of lectures on building crystals with good pictures of factory gear would be fun. ----------- [email protected] said: > Getting small feature sizes might be a challenge - when we did it where i > used to work, they did photo reduction onto a photoresist covered substrate. > I wonder if someone has a laser rig that could programmed to "draw" the > pattern on the resist at the right scale. Is electron-beam lithography a possibility? I remember smiling when I read that they turned down the power and used it as an electron microscope to find markers so they knew where the chip was actually located. Can you run up the power on a normal electron microscope to get a useful write time? -- These are my opinions.
