The laser-CVD of silicon oxide films on silicon substrates has been ca
rried out using a CW-CO2 laser in a parallel configuration, and with S
iH4 and N2O as precursor gases. In this paper we report the influence
of the reactant partial pressures on the film growth rate. The individ
ual apparent orders of the chemical reaction for SiH4 and N2O have bee
n determined.
