users.wfu.eduChemical Vapor Deposition (CVD) • Deposition can also take place due to a chemical reaction between some reactants on the substrate. • In this case reactant gases (precursors) are pumped in to a reaction chamber (reactor). • Under the right conditions (T, P), they undergo a reaction
Deposition - INRF
www.inrf.uci.eduThin dielectric films are deposited using plasma enhanced chemical vapor deposition (PECVD) or remote plasma chemical vapor deposition (RPCVD) of SiO2, Si3N4 or a-Si. The source gases for the PECVD SiO2 films are 5% SiH4 in N2 plus N2O; for SixNy films source gases include 5% SiH4 in N2 plus NH3 and N2.
