研究概要	本基盤研究は、低電圧・低消費電力・超高速・大容量移動体通信システムの実現のため、SiGe系のMOSとHBTを集積した、新しい低電圧・低消費電力・超高速・大容量移動体通信用システムオンチップの製作技術を開発することを目的として、ドイツ半導体物理学研究所研究チームとの国際学術研究として3年計画で推進している。本年度は、SiGe系半導体極微細構造の形成(反応雰囲気の高清浄化と基板表面吸着の制御、SiGe系半導体薄膜の形成、SiGe系半導体極微細構造の高選択異方性エッチング、SiGe系半導体への不純物の超高精度ドーピング)と、超高速通信用デバイス技術(高精度要素プロセス技術の開発、集積化デバイス製作プロセスの構築、超高速デバイス構造、デバイス試作と超高速動作の評価)の、基本要素の研究を実施した。特にMOS-HBT集積化デバイスの製作のため、ドイツ半導体物理学研究所に滞在した日本学術振興会・特別研究員山本の研究分担協力を得、また、SiGe系MOS-HBT集積化システムのためのSiGe系CVD低温選択成長の研究、SiGe系CVDにおける不純物のin-situ高精度ドーピングの研究、SiGe系極微細MOSデバイスの製作を行い、低温HBT製作プロセスにおけるSiGe低温成長による高濃度Pドープ、CドープによるB、Pの拡散抑制効果を用いた高速へテロHBT試作など、極めて重要な成果を得た。さらに、SiGeへのCの導入、ドープトSiGeからのドーパント不純物の拡散、SiGeの極微細MOSデバイスへの応用等を実現する等、研究発表論文にも示すように大きな成果を得た。
