Pecvd review
WebPlasma Enhanced Chemical Vapor Deposition (PECVD) is utilized to deposit films such as Si, SiO2, Silicon nitride, silicon oxynitride and Silicon carbide at temperatures (200-350C) lower than typical Low Pressure CVD process temperatures. Plasma assists in the break down of the reactive precursor thereby enabling the process at a lower temperature. WebPlasma-enhanced chemical vapor deposition (PECVD) is a chemical vapor deposition process used to deposit thin films from a gas state to a solid state on a substrate. Chemical reactions are involved in the process, …
