Description
図1に本実施形態の気相成長装置の構成を示す。図1に示すように、ウェーハwが成膜処理される反応室(チャンバー)11と、反応室11からの排気ガスの流量を制御するスロットルバルブ12、例えばスクリューロータを回転させることにより排気ガスを排出するドライポンプ(真空ポンプ)13が順次接続されている。
P2≦P1/2
となるようにドライポンプ13を制御することにより、反応室11内の安定した圧力調整が可能となるとともに、スクリューロータの回転数(ドライポンプの稼働量)を抑えることできる。
本実施形態においては、実施形態1と同様の気相成長装置が用いられるが、成膜の条件をより低圧としている。
本実施形態においては、実施形態1と同様の気相成長装置が用いられるが、反応室にウェーハを搬送する搬送室においても同様に圧力制御が行われている。
