Low-temperature (80–130°C) high-quality silicon nitride was grown on Si substrates using a SiH4 (5% in He)/NH3/Ar chemistry and ICPECVD technology. The influence of percentage SiH4, temperature, chamber pressure and source power on the wet etch ra

The composition of the gas phase during remote plasma-enhanced chemical vapour deposition (RPECVD) of SiO2 from a diluted SiH4N2OHe mixture was investigated by mass spectroscopy. We chose the gas flow rates such that no direct excitation of SiH
