The High School Student Who’s Building His Own Integrated Circuits

"...making DIY integrated circuits seemed impossibly out of reach. After all, building a modern fab is astronomically expensive: For example, in 2017 Intel announced it was investing US $7 billion to complete a facility for making chips with 7-nanometer-scale features. But Sam Zeloof was not deterred. This 17-year-old high school student has started making chips in his garage, albeit with technology that’s a few steps back along the curve of Moore’s Law.

Zeloof says he has been working on his garage fab, located in his home near Flemington, N.J., for about a year. He began thinking about how to make chips as his “way of trying to learn what’s going on inside semiconductors and transistors. I started reading old books and old patents because the newer books explain processes that require very expensive equipment.”

A key moment came when Zeloof found Jeri Ellsworth’s YouTube channel, where she demonstrated how she had made some home-brew silicon transistors a few years ago. “After I saw [Ellsworth’s] videos I started to make a plan of how I could actually start to do this.”

It took Zeloof about three months to replicate Ellsworth’s transistors. “That was getting my feet wet and learning the processes and everything, and acquiring all the equipment,” he says. “My goals from there were to build on what she did and make actual ICs.” So far, he has made only simple integrated circuits with a handful of components, but he is aiming to build a clone of the ur-microprocessor, the Intel 4004, released in 1971. “It’s got about 2,000 transistors at 10 micrometers.... I think that’s very attainable,” says Zeloof."
