Silicon Chip Fabrication at Home: Laser Doping


Somebody has been making semiconductors for pert near 75 years, but the explanations we get on how it's done are mostly very hand wavy and not at all specific, so it's very cool to see somebody actually doing this. There are still any number of mysteries, like where are these E-Bay wafers coming from, and how is he getting the laser beam to scan across those tiny little rectangles, but if we watched some of his other videos the answer might be revealed.
