3C& Semiconductor Manufacturing

Semiconductors are made in a very clean environment, and some processes are carried out in a vacuum. For example, many semiconductor components, such as optical disc drives (CD, VCD and DVD) and semiconductor lasers used in optical fiber communication, microwave integrated circuits used in radar or satellite communication equipment, and even many ordinary microelectronic integrated circuits, have a big part of the manufacturing process carried out in a vacuum chamber. The better the vacuum class, the better the performance of the device. 

Semiconductor manufacturing equipment uses stepper motors, servo motors and precise mechanical transmission parts to automate and control the process. At the same time, it is important that the motors and mechanical parts can work reliably for a long time in ultra-high-vacuum (UHV) and high/low temperature environments, without releasing harmful substances which cause contamination to vacuum environments.
