chemical vapor deposition using plasma enhanced chemical vapor deposition technology, low basic temperature, fast deposition rate, deposition of silicon nitride, amorphous silicon and microcrystalline silicon films on optical glass, silicon, quartz, stainless steel and other substrate materials, good film forming quality, fewer pinholes, not easy to crack. It is suitable for the preparation of amorphous silicon and microcrystalline silicon thin film solar cell devices, and can be widely used in the research and small batch preparation of thin film materials in colleges and universities and scientific research institutes.
PECVD equipment uses the principle of flat plate capacitive glow discharge to dissociate the process gas passing into the deposition chamber and generate plasma. The dissociated groups re-react chemically in the plasma. Due to the presence of plasma, the decomposition, combination, excitation and ionization of gas molecules are promoted, and the formation of reactive groups is promoted, thus reducing the deposition temperature. A film is deposited on a substrate at a certain temperature. The density and energy of the plasma can be adjusted according to the process, and the growth rate and microstructure of the film can be controlled.
