Description
a=((b/tan54.7)×2)+c
となる。従って、この関係式を用いて、マスク9の開口部の幅を決定することができる。
まず、図2(a)に示すように、表面上にTaSiNからなるエネルギー発生素子1を有する、厚み725μmの第1の基板2を用意した。第1の基板2としては、エネルギー発生素子を有する面の結晶の面方位が(100)であるシリコン基板を用いた。第1の基板2の表面側には、アルミニウムで形成された犠牲層4を形成し、さらに電気的な接続を行う電極パッドや、エネルギー発生素子1の配線、エネルギー発生素子1を駆動するための半導体素子等を形成した。エネルギー発生素子及びその配線等は、SiNで形成された絶縁層3で覆われており、第1の基板2には、後でマスクを貼り合わせる際に用いるアライメントマークが形成されている。また、第1の基板2の裏面側には、シリコンの酸化膜である裏面層5を形成した。
実施例2では、実施例1と違う点として、感光性樹脂層6を塗工する塗工液の組成を以下の通りとした。
・3−メトキシ−3−メチル−1−ブタノール;59質量部
・メタクリル酸メチル/メタクリル酸/テトラヒドロフルフリルメタクリレートを質量比65/15/20で混合したモノマー;40質量部
・VPE−0201(商品名、和光純薬製);1質量部
また、実施例1では、流路パターン7を現像して除去してから第2の基板8を貼り合わせたが、実施例2では、この時点では流路パターン7を現像せずに、プロキシミティ露光によって潜像状態にしておいた。
