Fab2

Operates compact semiconductor fabrication facility

Overview

Fab2 is building a compact semiconductor fabrication facility to produce chips for smartphones, computers, and other electronics. The facility runs semiconductor manufacturing, using in-house tools and processes to create smaller, more efficient chips with advanced geometries. The business sells manufactured chips to tech companies and may offer fabrication services to others, providing both product sales and contract manufacturing. What sets Fab2 apart from larger, traditional fabs is its focus on agility: a smaller footprint, faster ramp, and the ability to adapt quickly to new processes and geometries. The goal is to make semiconductor manufacturing faster and more accessible by offering a nimble, capable fab that can serve multiple industries and drive ongoing chip innovation.
