Stage 7 of 12Front-end manufacturing
Fab
The cleanroom where chips are made.
What happens here?
The fabrication plant integrates hundreds of process steps into a single, tightly-controlled cleanroom line. Foundries run this for others; IDMs run it for their own products. It is the most capital-intensive link in the chain.
