Abstract

Si1-xGex alloys were formed by high-dose (on the order of 1016 cm−2) germanium ion implantation into Si. It was found that the crystalline quality of the SiGe layer was improved by maintaining the substrate at low temperature during implantation. Cross-sectional transmission electron micrographs indicated a considerable reduction in the end-of-range defects. This improvement was further confirmed by electrical characterization of p-n junctions formed in the SiGe layer.
