A friend of mine used to work for AMD in Austin and in his office had several wafers mounted on stands and even several dies used to transfer the images to the wafer, was pretty awesome. Too bad AMD layed him off, funny cause he left a job at intell to work for amd.If anybody ever gets the chance, its really cool to take a tour of a microchip fab. Plus you get to wear to awsome suits.
Back about 4-6 years ago in high school I got to spend a week at AMD fab 25 (was in the process of being transferred to Spansion) in Austin, TX which now makes flash memory instead of cpus(used to make k6 and k7 chips). The clean room there is actually a higher class than most of the new cpu facilities because they actually transfer the wafers in an open container between stages of manufacturing. The guys giving us the tour said they would kill us if we touched a wafer or pressed any buttons.
