via the RSGB: Schoolboy makes silicon chips at home

We normally think of silicon chip fabrication as being a cutting-edge practice, requiring huge investments and hundreds of people.

However, we learned recently of Sam Zeloof, a 17-year-old high school student in the USA, who is making his own chips in his garage.

Using ingenuity and equipment purchased via eBay, including things like an electron microscope he bought for less than the cost of shipping, Sam can fabricate features down to about 2 microns, though he says contamination issues mean 10 microns is the practical limit for functioning devices, because, after all, he’s working in a garage, not a clean room—more details on the IEEE Spectrum website:
