IBM is now offering 45-nanometer chipmaking "foundry" services based on its silicon-on-insulator technology.
Foundries have become a big business in the chip industry. Taiwan Semiconductor Manufacturing Company (TSMC), the largest foundry in the world, builds chips for Advanced Micro Devices and Nvidia. AMD announced in October that it was spinning off its manufacturing operations into a foundry.
Most of the advanced manufacturing technology offered to date at foundries has been based on a 65-nanometer process. Typically, the smaller the chip geometries, the faster or more power-efficient the chips are.
