According to Taiwan media, there is a mysterious Area 51 in TSMCs Longtan sealing and testing plant, which cant be said to the public, and its confidentiality is tight.
Mysterious Area 51 mainly develops products for American companies. The confidentiality clauses signed by the participating manufacturers are not only the two parties, but even as many as five parties, striving to achieve information security and strict supply chain management.
According to Taiwan media, TSMCs management of suppliers is also very accurate. If the supplier of factory a is located, they can only move in the location of area a where their machines are located. If they wander to the areas where they should not appear, the radio frequency identification chip (RFID) on the dust-free clothes of the staff will work.
If someone accidentally brings a smart phone into the factory and is found by the metal detector door, the employee will be deducted from the performance bonus; the supplier is required to leave the factory directly and not to enter.
TSMC, founded in 1987, is the worlds largest foundry semiconductor manufacturer with customers including apple, Qualcomm, etc. Its headquarters are located in the Hsinchu Science Industrial Park in Hsinchu, Taiwan.
