In the microelectronics industry, a foundry (also called a fab for fabrication plant) is a factory where devices like integrated circuits are manufactured. When the term "Foundry" is applied to a fab, it means that there are many devices being made at that fab for one or more customers. A fab that only has one product, or just one customer is generally not called a foundry.
