Claims (5)
- シリコン本体の表面に、ある材料の補助層が設けられ、その上に、酸化処理の間に、前記シリコン本体のシリコン上よりも厚くシリコン酸化物の層が形成され、その後、フィールド分離領域が形成される位置において、前記補助層内に複数の開口が形成され、前記シリコン本体の前記表面内に複数の溝が形成され、その後、酸化処理が行われて、前記複数の溝及び前記複数の開口の壁にシリコン酸化物の層が設けられ、しかし、前記複数の開口近傍の前記補助層がその厚み全体に渡って酸化されることはなく、その後、続いて、分離材料の層が前記複数の溝及び前記複数の開口が完全に満たされるような厚みで堆積され、前記補助層の非酸化部分が露出するまで平坦化処理が行われ、その後、前記補助層のこの部分が除去される半導体装置の製造方法であって、シリコンとゲルマニウムとを備える層が補助層として前記シリコン本体の前記表面に施されることを特徴とする方法。
- 前記シリコン本体の前記表面に、SixGe1−x−yCy、ここでは、0.70<x<0.95そしてy<0.05の層が前記補助層として設けられることを特徴とする請求項1に記載の方法。
- 前記補助層は、この層がその厚み全体に渡っては前記酸化処理中に酸化物に変化しないような厚みとされることを特徴とする請求項1又は2に記載の方法。
- シリコン窒化物の層が前記補助層に施され、前記シリコン窒化物の層内並びに前記補助層内に前記複数の開口が形成されることを特徴とする請求項1又は2に記載の方法。
- 前記シリコン本体の前記表面に前記補助層を施す前に、前記表面にシリコン酸化物の層が設けられ、そして、該シリコン酸化物の層内に前記複数の開口が形成されることを特徴とする請求項1、2,3又は4にいずれかに記載の方法。
