Product introduction:
The large-diameter PECVD system uses radio frequency to ionize the gas containing the film constituent atoms to form a plasma locally. The plasma has a strong chemical activity and is easy to react to deposit the desired film on the substrate. The system is extensive Used to deposit high-quality, SiO2 film, Si3N4 film, diamond film, hard film, optical film, carbon nanotube (CNT), graphene materials, etc.
