Semiconductor Foundries and Fabs List

semiconductor foundry fabs manufacturing companies

Semiconductor foundries (also called fabs, short for fabrication plants) are specialized manufacturing companies that produce semiconductor chips (integrated circuits or ICs) based on designs provided by other companies. This page lists semiconductor foundries or fabs across the globe.

What Semiconductor Foundries Do

  1. Manufacture Chips: They use advanced photolithography, etching, deposition and ion implantation processes to fabricate silicon wafers into working chips with millions to billions of transistors.

  2. Serve “Fabless” Companies: Most chip design companies like Qualcomm, NVIDIA, AMD and Broadcom do not own fabs. They rely on foundries like TSMC or Samsung Foundry to physically manufacture their designs.

  3. Provide Process Technologies: Foundries offer various technology nodes like 3nm, 5nm, 7nm, 28nm, etc., which refer to the transistor size and impact chip performance, power consumption and cost.

  4. Quality & Yield Optimization: They optimize chip yields (the number of usable chips per wafer) and ensure high reliability through cleanroom environments and strict process controls.

  5. Packaging & Testing (sometimes): Some foundries offer backend services like chip packaging and testing, though many customers use third party OSATs (Outsourced Semiconductor Assembly and Test providers).
