Claims (5)
- 被成膜基板を載置するサセプタを収納した成膜室内に反応ガスを供給して、被成膜基板の表面に膜を形成する成膜装置であって、上端にサセプタ用の支持部材が連結され、成膜室の底壁部に開設した貫通孔を通して下方にのびる回転軸と、成膜室の下方に配置された回転軸用の回転機構部とを備え、回転機構部は、成膜室の底壁部の下面との間に筒状の押え部材を介設した状態で配置した、回転軸を軸支する軸受と、この軸受の下方に配置した、回転軸を回転駆動する駆動源とを有し、
押え部材に、環状の分布室と、この分布室に周囲1個所からパージガスを導入する導入口とが形成されると共に、押え部材と回転軸との間の隙間に分布室からのパージガスを噴出するノズル孔が周方向の間隔を存して複数形成され、
前記底壁部は、前記反応ガスを排気する排気口を有し、この排気口を介して前記反応ガスとともに前記パージガスが排気されることを特徴とする成膜装置。 - 前記導入口から離れるに従って前記ノズル孔の孔径を大きくすることを特徴とする請求項1記載の成膜装置。
- 前記導入口から離れるに従って前記ノズル孔間の周方向間隔を短くすることを特徴とする請求項1記載の成膜装置。
- 前記各ノズル孔は、前記押え部材と前記回転軸との間の隙間にパージガスを斜め上向きに噴出するように形成されることを特徴とする請求項1〜3の何れか1項記載の成膜装置。
- 前記押え部材と前記回転軸との間の隙間の途中にダスト受け部が設けられ、前記各ノズル孔は、ダスト受け部よりも上方の隙間の部分にパージガスを噴出するように形成されることを特徴とする請求項1〜4の何れか1項記載の成膜装置。
