Detailed Parameters Of The Product
Descriptions of PECVD furnace:
PCVED by microwave or radio frequency make gas ionization containing film the constituent atoms,in a local plasma formation,and plasma chemical activity is very strong,is easy to react,sedimentary out the desired film on substrate,it widely used product high quality sio2 film,si3N4 film,diamond film,hard thin film,optical thin film and CNT etc.
Outstanding features of PECVD furnace :
1. Lower temperature processing compared to conventional CVD.
PECVD tube furnace is widely used product high quality sio2 film,si3N4 film,diamond film,hard thin film,optical thin film and CNT etc.
2. Film stress can be controlled by high/low frequency mixing techniques.
3. Control over stoichiometry via process conditions.
4. Offers a wide range of material deposition, including SiOx, SiNx, SiOxNy andAmorphous silicon (a-Si:H) deposition.
We have a wide range of different optional function furnace to meet different heating requirement, also we accept customer design furnace R&D working, please email us your specific requirement, we will recommend most reasonable choice for you, thanks!
