Abstract

Blanket B doped SiGe(C) and selective Si epitaxial growth using hot wall LPCVD system have been investigated. We achieved good B-doping uniformity of the SiGe(C) film using other doping, gas besides B₂H₆. The sheet resistance in-wafer uniformity in 200mm diameter wafer of the B-doped SiGe(C) was around 2 sigma %. The good epitaxial layer quality and the excellent thickness uniformity of the B-doped SiGe(C) film were recognized by high-resolution XRD. We also achieved selective Si growth up to 100nm for SiO₂ and SiN patterned wafer using the high-throughput ultraclean hot-wall LPCVD system. The cross-sectional TEM image of selective-Si/Si(001)- substrate interface showed good epitaxial quality with no dislocation and stacking fault.
