Abstract Hydrogen amorphous silicon nitride (SiN x:H abbreviated SiN x) films were grown on multicrystalline silicon (mc-Si) substrate by plasma enhanced chemical vapour deposition (PECVD) in parallel configuration using NH 3 /SiH 4 gas mixtures The mc-Si wafers were taken from the same column of Si cast ingot After the deposition process the layers were oxidized (thermal oxidation) in
Abstract Plasma silicon nitride film has been widely applied to a passivation layer of photo-electric devices Since its physical and electrical properties are strongly dependent on a variety of deposition parameters it is important to evaluate the film composition to control the deposition process
