About

Fab2 is building small, self-contained semiconductor fabs that integrate the tools and robotics needed to manufacture custom silicon in days rather than months. By vertically integrating both the fab and the equipment inside it, Fab2 aims to make chip development dramatically faster, cheaper, and more iterative.
