Terafab will close the gap between today's chip production and the future's demand —

a future among the stars.

## Harnessing the power of the Sun

- Maximize utilization of the Sun's energy
- Produce AI chips at scale
- Unlock interplanetary travel

## We're builders.

*We've done the impossible before.*

## A chip factory built for Earth and orbit

Combining logic, memory, and advanced packaging all under one roof
