Fab2 designs and builds every tool in its fabs in-house, from pumps, valves, and gas lines to lithography and the vacuum chambers that house it. The company assembles those components into machines, the machines into complete fabs, and then aims to mass-produce the fabs themselves. It pairs the hardware with Studio, an in-browser, collaborative EDA tool for layout, schematic, and simulation work, previously branded as Atomic Studio.
Rather than moving 300mm wafers through ginormous production lines, Fab2 targets small, software-defined fabs that pattern chips far smaller than a wafer and turn prototypes around in hours. Zeloof built the concept's proof point as a teenager, fabricating lithographic chips in his parents' garage down to roughly 300nm features before co-founding this company with Keller in 2022.
The method's main constraint, however, is throughput. Electron-beam lithography writes patterns directly rather than projecting them through a mask, which makes it slow: a single patterning step on a small chip can take far longer than an EUV scanner needs to expose an entire 300mm wafer. That's a big tradeoff that only really suits prototyping and low-volume runs rather than high-volume production at commercial foundries.
Fab2 now operates three sites: a 120,000 square foot facility in Austin serves as the new headquarters for research and production, a 30,000 square foot site in Lockhart houses the "fab fab" itself, and the original 25,000 square foot "garage fab" remains in San Francisco.
