Description
以下、図面を参照して実施形態1について詳細に説明する。
図1は、実施形態1にかかる基板処理装置1の構成の一例を示す図である。実施形態1の基板処理装置1は、例えばウェハWの外縁部に環状の膜を形成する薬液塗布装置として構成されている。
次に、図6~図8を用いて、実施形態1の半導体装置の製造方法について説明する。実施形態1の半導体装置の製造方法は、基板処理装置1における膜FLの形成処理を含む。
次に、図9を用いて、実施形態1の基板処理の例について説明する。図9は、実施形態1にかかる基板処理の手順の一例を示すフロー図である。
半導体装置の製造工程で、ウェハの外縁部に環状の膜を形成する処理が行われることがある。環状の膜は、例えばウェハの中央部に微細なパターン等を形成する際、外縁部を保護する保護膜として用いられ、外縁部にまで微細パターンが形成されてしまうことを抑制する。ウェハをハンドリングする際などに微細パターンが外縁部にあると、それが破壊されてパーティクルとなることが有り望ましくないからである。
次に、図11を用いて、実施形態1の変形例1の薬液ノズル20aについて説明する。変形例1の薬液ノズル20aは、上述の実施形態1の薬液ノズル20とは異なる配置の吐出孔23aを備える。
次に、図12及び図13を用いて、実施形態1の変形例2,3の構成について説明する。変形例2,3では、固化膜を形成する方法が実施形態1とは異なる。
以下、図面を参照して実施形態2について詳細に説明する。実施形態2では、ウェハの外縁部を冷却する点が上述の実施形態1とは異なる。
図14は、実施形態2にかかる基板処理装置2の構成の一例を示す図である。実施形態2の基板処理装置2は、例えばウェハWの外縁部に環状の膜を形成する薬液塗布装置として構成されている。なお、図14において、上述の実施形態1の図1と同様の構成には同様の符号を付して、その説明を省略する。
実施形態2の基板処理装置2によれば、上述の実施形態1の基板処理装置1と同様の効果を奏する。
次に、実施形態2の変形例1,2の構成について説明する。変形例1,2では、ガスノズル、または冷却ノズルの個数が実施形態2とは異なる。
次に、実施形態2の変形例3の基板処理装置について説明する。変形例3の基板処理装置では、ウェハの外縁部を冷却する方法が実施形態2の基板処理装置2とは異なる。
上述の実施形態1,2及び変形例1~3では、レジスト材を含む薬液を用い、環状の膜FLとしてレジスト膜を形成することとした。しかし、環状の膜FLの材質は、例えばウェハWのエッチング処理時に用いられるマスクパターンの材質等に応じて種々に選択可能である。
