High vacuum PECVD system

Application

Detailed Parameters Of The Product

Product Overview:
PT high vacuum PECVD system is composed of tube furnace, vacuum system, gas supply system, radio frequency power supply system, etc. The system is mainly used in the growth of metal thin films, ceramic thin films, composite thin films, graphene, etc. The PECVD system is easy to add functions and can expand the functions of plasma cleaning and etching. The PECVD system has the advantages of high film deposition rate, good uniformity, high consistency and stability.

Main features of high vacuum PECVD system :

1. Change the gas in the quartz vacuum chamber to an ion state through the radio frequency power supply.

2. PECVD requires a lower temperature than ordinary CVD for chemical vapor deposition.

3. The stress of the deposited film can be controlled by the frequency of the radio frequency power supply.

4. PECVD has higher chemical vapor deposition rate, better uniformity, consistency and stability than ordinary CVD.

5. Widely used in the growth of various thin films, such as SiOx, SiNx, SiOxNy and amorphous silicon (a-Si:H).
