Description
図1は、本発明の実施の形態1に係る炭化珪素エピタキシャルウエハの製造装置を示す断面図である。エピタキシャル成長を行う成長炉1内に、炭化珪素基板2を載置するウエハホルダー3が設けられている。第1のガス導入口4は、炭化珪素エピタキシャル層を成長させるためのプロセスガスとしてキャリアガスと原料ガスを成長炉1内に導入する。第1のガス排気口5はプロセスガスを成長炉1から排出する。
図6は、本発明の実施の形態2に係る炭化珪素エピタキシャルウエハの製造方法を示すフローチャートである。実施の形態2の製造方法に用いる製造装置は実施の形態1と同様である。
図7は、本発明の実施の形態3に係る炭化珪素エピタキシャルウエハの製造方法を示す成長シーケンスである。本実施の形態でも実施の形態1のステップS3と同様に、成長炉1を1650℃程度まで加熱した後、成長炉1内に第1のガス導入口4から原料ガスを供給することにより炭化珪素基板2の表面上に膜厚10μmの炭化珪素膜をエピタキシャル成長させる。例えば、Si原子の供給源としてシランガス(SiH4)を流量500sccmで供給し、C原子の供給源としてプロパンガス(C3H8)を流量200sccmで供給する。N型ドーピングとして窒素ガスを用いる。また、N型ドーピングとして、基板界面でキャリア濃度が1×1017/cm3となり、活性領域でキャリア濃度が8×1015/cm3となるように窒素ガスを供給する。その後、原料ガスの供給を停止し、室温まで降温させる。
本発明の実施の形態4の製造方法は実施の形態1に示すフローチャートと同様であるが、成長炉1とウエハホルダー3を炭化珪素エピタキシャルウエハの製造装置から取り出し、別の窒化専用の装置を用いて窒化工程を実施する。それ以外は実施の形態1の製造方法と同様である。
図8は、本発明の実施の形態5に係る炭化珪素エピタキシャルウエハの製造方法を示すフローチャートである。本実施の形態に係る炭化珪素エピタキシャルウエハの製造装置は実施の形態1と同様であるが、第2のガス導入口6はガス流量制御装置と圧力制御装置を介して酸化又は酸窒化用の安定化ガスのボンベに接続されている。安定化ガスはO2、NO、N2O、NH3、H2O、他の酸素含有ガス、他の窒素含有ガスの何れかである。
