The growth and characterization of heteroepitaxial Si_(l-x)Ge_x films grown by the RTCVD (Rapid Thermal Chemical Vapor Deposition) method were described. For the growth of Si_(l-x)Ge_x heteroepitaxial layers, SiH₄/ GeH₄ / H₂ gas mixtures were used. The growth conditions were varied to investigate their effects on the Si / Ge composition ratios, the interface abruptness and crystalline properties. The experimental data shows that the misfit threading dislocation in Si_(l-x)Ge_x / Si heteroepitaxial film of about 400 A thickness was not observed at the growth temperature of as low as 650℃, and the composition ratios of Si / Ge changed linearly with SiH₄ / GeH₄ gas mixing ratios in our experimental ranges. In the in-situ boron doping experiments, the doping abruptness would be controlled within several hundreds Å/decade.
