Description
次に、本実施形態に係る基板処理装置の構成例について説明する。図1は、実施形態に係る基板処理装置の概略構成を示す断面図である。本実施形態では、基板処理装置を、処理対象の基板としての半導体ウエハWに対してプラズマエッチングを実施するプラズマ処理装置1とした場合を例にする。なお、基板処理装置は、プラズマ処理装置1に特に限定されるものではない。
イオン液体は、イオンのみで構成される室温で液体の塩の総称である。イオン液体は、蒸気圧がほぼゼロ、不揮発性(高温でも真空中でも揮発しない)、高いイオン電導性、熱伝導性が高い、熱的に非常に安定、難燃性などの特徴を有する。また、イオン液体は、親水性のものと疎水性のものがあり、高い極性を有するなどの特徴を有する。イオン液体は、液体であるために配管22a、22bを通して処理容器10内へ供給することが可能である。
