A semiconductor FAB is a production plant where devices such as integrated circuits are manufactured. These facilities are equipped with clean rooms and sophisticated equipment to precisely control environmental conditions, ensuring the high quality and purity required for semiconductor manufacturing.

Outsourced Semiconductor Assembly and Test (OSAT) companies take over post-fabrication. They cut the manufactured wafers into individual chips, package them, and conduct rigorous testing (in many cases before cut/dicing) to ensure they meet the required specifications. OSATs allow semiconductor companies to focus on the highly specialized chip design process (and fabrication) without bearing the brunt of assembly and testing processes.
