About
Fab2 is a semiconductor startup that designs and builds every piece of equipment inside its fabs in-house, then mass-produces small fabs assembled from that equipment. The company operates a 'fab fab' — a factory that makes factories — building everything from basic components like pumps and valves to lithography tools and vacuum chambers. Founded in 2022 as Atomic Semi and rebranded to Fab2 in July, the company also develops Studio, a browser-based collaborative chip-design tool. With the tagline 'We print chips,' Fab2 aims to democratize semiconductor manufacturing by reducing barriers to entry in foundry work.
