Abstract
Description
本発明の一実施形態に係る基板保持具が用いられる基板処理装置の一例について説明する。図1は、本発明の一実施形態に係る基板処理装置1の概略縦断面図である。図2は、図1の基板処理装置1の処理容器24近傍の概略横断面図である。
前述した基板処理装置1を用いた基板処理方法の一例について説明する。尚、以下では、基板処理装置1を用いたプラズマALD成膜処理を室温付近で行うことにより、ウエハWの被処理面にシリコン酸化膜(SiO2膜)を形成する場合を例にとって説明する。この場合、プラズマにより活性化する第1のガスとして酸素ガスを使用し、第2のガスとしてシラン系ガスを使用する。シラン系ガスと酸素ガスとを交互に供給すると共に、酸素ガスをプラズマにより活性化させることで、ウエハWの表面にSiO2膜を形成する。しかしながら、基板処理方法は、この点において限定されるものではない。成膜する膜種は他の膜種であってもよい。また、プラズマALD成膜処理を例にとって説明するが、プラズマCVD処理、プラズマ改質処理、プラズマ酸化拡散処理、プラズマスパッタ処理、プラズマ窒化処理等のプラズマを用いる他の基板処理に対しても、適用することができる。
本発明の一実施形態に係るウエハボート28及び基板処理装置1の作用・効果について説明する。
本発明の一実施形態に係るウエハボート28を用いて、直径が300mmのシリコンウエハ上にSiO2膜を成膜した(以下「実施例」という。)。また、比較のために、前述した凸部284aを有していないウエハボートを用いて、直径が300mmのシリコンウエハ上にSiO2膜を成膜した(以下「比較例」という。)。
