Abstract

The growth properties of β-SiC on (100) Si grown by rapid thermal chemical vapor deposition, using a single precursor (methylsilane) without an initial surface carbonization step, were investigated. An optimum growth temperature at 800 °C was found to grow single crystalline SiC. The single crystalline SiC films were used to be the buffer layers for the growth of subsequent poly Si films. For the poly Si grown at low temperature (625 °C), the (110) Si diffraction was found to be the dominant peak in the X-ray diffraction spectra at the initial growth stage, while the poly Si grown on oxide was dominated by (111) texture. A small average misfit (4%) between (110) Si planes and (100) SiC planes was proposed to explain this effect. To apply the Si/SiC/Si multilayers, SiC/Si heterojunction bipolar transistors (HBT's) were fabricated and compared to Si bipolar junction transistors.
