Description
[プラズマ処理装置の構成]
図1は、一実施形態に係るプラズマ処理装置の構成を示す概略断面図である。プラズマ処理装置100は、気密に構成され、電気的に接地電位とされた処理容器1を有している。この処理容器1は、円筒状とされ、例えばアルミニウム等から構成されている。処理容器1は、プラズマが生成される処理空間を画成する。処理容器1内には、被処理体(work-piece)である半導体ウエハ(以下、単に「ウエハ」という。)Wを水平に支持する載置台2が設けられている。載置台2は、基材(ベース)2a及び静電チャック(ESC:Electrostatic chuck)6を含んで構成されている。基材2aは、導電性の金属、例えばアルミニウム等で構成されており、下部電極としての機能を有する。静電チャック6は、ウエハWを静電吸着するための機能を有する。載置台2は、支持台4に支持されている。支持台4は、例えば石英等からなる支持部材3に支持されている。また、載置台2の上方の外周には、例えば単結晶シリコンで形成されたフォーカスリング5が設けられている。さらに、処理容器1内には、載置台2及び支持台4の周囲を囲むように、例えば石英等からなる円筒状の内壁部材3aが設けられている。
次に、図2を参照して、載置台2の要部構成について説明する。図2は、一実施形態に係る載置台2の要部構成を示す概略断面図である。
図6及び図7を用いて、冷媒流路2dを通流する冷媒の流れ方向に対して90度よりも大きい角度θで傾斜するように導入流路2bを冷媒流路2dに接続したことよる冷媒の流速分布の変化を説明する。図6は、角度θと、冷媒流路2dの内壁のうち、接続部分2gに対向する領域と他の領域との間で発生する冷媒の流速の差との関係をシミュレーションするためのモデルの一例を示す図である。図7は、角度θと、冷媒流路2dのうち、内壁の接続部分2gに対向する領域と他の領域との間で発生する冷媒の流速の差との関係のシミュレーション結果の一例を示す図である。図7は、図6に示すモデルを用いたシミュレーションにより得られたものである。
