Description
下部絶縁層6として直径298mmのポリイミドシート(東レ・デュポン社製商品名カプトンH:厚さ125μm)を用意し、この表面をならす目的で予めイオンプレーティング法によって処理して0.1μmのクロム層を形成した。次いで、このポリイミドシートのクロム層上にイオンプレーティング法によって直径296mm、膜厚0.5μmの銅からなる電極層を形成して、硝酸系エッチング液を用いたエッチングにより、図1及び2に示すような第一電極2及び第二電極3を得た。ここで、仮想セル幅L=5mmとし、それぞれ4.5mm×4.5mmの大きさを有した第一電極部2aと第二電極部3aとが、x方向及びy方向のセルに交互に並ぶようにして、尚且つ、x方向及びy方向ともに隣接する電極部間の隙間dを1mmとして配置した(直径方向には最大59個の電極部を配置)。また、仮想セル内に配置された第一電極部2及び第二電極部3は、互いに等電位となるように、いずれも幅0.5mmの帯状の第一連結部2b及び第二連結部3bによって連結されるようにした。
電極層を形成する第一電極2及び第二電極3について、図4に示すとおり、4×4の仮想セルの頂点部分の電極部を欠落させ、電極層の表面において第一電極部2aが欠落した電極欠落部2cと第二電極部3aが欠落した電極欠落部3cの数が同数になるようにした以外は実施例1と同様にして電極シートを得た。次いで、上部絶縁層1の表面にマスクをかぶせ、ポリイミド専用アルカリ系エッチング液(三菱製紙株式会社製商品名ポリイミドエッチング液)を用いてエッチングを行い、電極欠落部2c、3cの仮想セルに対応する箇所以外のポリイミドシートを深さ10μm除去し(絶縁層凹部1cに相当)、5mm×5mm×高さ10μmの絶縁層頂部1aを形成した。次いで、絶縁層頂部1aを形成した電極シートを実施例1と同様にしてアルミニウム製金属基盤に固着し、実施例2に係る双極型静電チャックを完成させた。
