Abstract
Description
処理容積112内に位置する中間媒体、即ち、固体スラリ、ゲル、及び/または液体媒体といった非気相媒体を、その場所に閉じ込め得る。一例においては、閉じ込めリング154は、中間媒体が処理容積112内に配置された際、例えば物質及び/または液体媒体といった中間媒体を、基板140上に配置されたフォトレジスト層150の表面全体を覆うレベルに保持するのに十分な長さ、即ち約0.5mm〜約10mmの間の既定の距離dを有し得る。代わりに、閉じ込めリングは、基板140を所望の位置にガイドするのを助けるため、基板支持体アセンブリ138に向かって下方に延伸しながら、電極アセンブリ116の端部に配置され得る。一例においては、閉じ込めリング154は、セラミック材料、導電性材料、誘電体材料、または、処理容積112内に位置する中間媒体に対して化学的に不活性な、他の好適な材料から製造され得る。
