Atomic Semi, the semiconductor equipment startup founded by chip architect Jim Keller, has rebranded as Fab2 and moved its headquarters to Austin, Texas, with a vision of mass-producing small fabs. According to Tom’s Hardware, Fab2’s core idea is a “fab fab”: it designs and builds all of its own equipment, from pumps, valves, and gas lines to lithography tools and vacuum chambers, then assembles the components into machines and the machines into a complete fab.
