1. Lower sedimentation temperaturetIJMuffle Furnace,Tube Furnace,Vacuum Furnace,Atmosphere Furnac
Low temperature process: PECVD utilizes plasma to excite gas reactions and can achieve deposition at lower temperatures (usually between 100 ° C and 400 ° C), which is particularly important for temperature sensitive substrates such as organic materials, plastics, and certain metals.tIJMuffle Furnace,Tube Furnace,Vacuum Furnace,Atmosphere Furnac
Thermal sensitive substrate protection: Depositing at lower temperatures can avoid thermal damage to the substrate and protect its physical and chemical properties.
