[0002] A semiconductor device is an electronic device whose conductivity is between a good conductor and an insulator. It uses the special electrical characteristics of semiconductor materials to complete specific functions. It can be used to generate, control, receive, transform, amplify signals and perform energy conversion. The semiconductor of semiconductor devices The material is silicon, germanium or gallium arsenide, which can be used as rectifiers, oscillators, light emitters, amplifiers, photometers and other equipment. In order to distinguish them from integrated circuits, they are sometimes called discrete devices. Most of the two-terminal devices The basic structure is a PN junction. When processing semiconductor devices, manual loading and unloading and positioning operations are required, which cannot meet the requirements of modern production, and the safety factor of manual operation is low.
