Low temperature polysilicon manufacturing process

摘要

A low temperature polysilicon manufacturing method. A system for performing physical vapor deposition is used to form an amorphous silicon film with micro-crystals therein. The amorphous silicon film is annealed at a temperature between 400° C. to 500° C. for about 6 to 16 hours to form a polysilicon film. The polysilicon film can be further processed into a low-temperature polysilicon film transistor.
