Fonderie

In brief

The factory that physically manufactures chips designed by others. Designing a chip and knowing how to manufacture it are two different skills. A foundry specialises in the latter, and such facilities are extremely rare.

Precise definition

An integrated circuit manufacturing plant (foundry) that produces chips designed by third parties, in line with the fabless model. Cutting-edge capabilities are concentrated amongst a few players, foremost among them TSMC in Taiwan, making this a major source of strategic dependence.
