Description
一実施形態に係る半導体膜の形成方法について、シリコン膜を形成する場合を例に挙げて説明する。一実施形態に係るシリコン膜の形成方法は、ホールやトレンチ等の凹部に成膜とエッチングとを交互に繰り返して埋め込み特性が良好なシリコン膜を生産性良く形成する方法である。シリコン膜は、例えばノンドープ膜であってもよく、ドープ膜であってもよい。ドープ膜のドーパントとしては、例えばリン(P)、ボロン(B)、ヒ素(As)、酸素(O)、炭素(C)が挙げられる。図1は、シリコン膜の形成方法の一例を示す工程断面図である。図1(a)から図1(g)は、シリコン膜の形成方法の各工程の断面を示す。
上記の半導体膜の形成方法を実施することができる成膜装置について、多数枚の基板に対して一括で熱処理を行うバッチ式の縦型熱処理装置を例に挙げて説明する。但し、成膜装置は、縦型熱処理装置に限定されるものではなく、種々の装置であってよい。例えば、成膜装置は、基板を1枚ずつ処理する枚葉式の装置であってもよい。また、例えば処理容器内の回転テーブルの上に配置した複数枚の基板を回転テーブルにより公転させ、原料ガスが供給される領域と、原料ガスと反応する反応ガスが供給される領域とを順番に通過させて基板上に成膜するセミバッチ式の装置であってもよい。
一実施形態に係る半導体膜の形成方法による効果を確認するために行った実施例について説明する。実施例では、上記の縦型熱処理装置1により半導体膜の一例であるシリコン膜を形成した。
