Abstract:
Application of N2 instead of NH3 as precursorgas in Plasma Enhanced Chemical Vapor Deposition (PECVD) of SiNx:H can have significant advantages with respect to safety and environment. In this paper we will show that for MicroWave- PECVD, SiNx:H with good bulk passivating properties can be obtained if only N2 and SiH4 are used as process gasses. A drawback of the current SiNx:H grown with N2 as precursor gas is the higher absorption at shorter wavelengths with respect to SiNx:H grown with NH3 as precursor gas.
