Description
基板の表面側に前記エネルギー発生体を形成する工程と、前記エネルギー発生体を形成した前記基板の表面に、前記液流路および前記吐出口が形成される部材である天板部材を形成する工程と、前記天板部材を形成した前記基板を、その裏面側から薄化する工程とを有することを特徴とする。
まず、図2に示すように、厚板の基板であるシリコン基板101の表面にTaN膜およびAl膜をスパッタ法にて成膜し、フォトリソグラフィ技術を用いて所定のパターンにパターニングすることで、TaN膜からなる発熱抵抗体13および配線14を形成する。ここでは、シリコン基板101として厚さが625μmのものを用いた。また、発熱抵抗体13のサイズは、30μm×30μmとした。必要に応じて、発熱抵抗体13および配線14の上に保護層(不図示)を設けてもよい。
上述した例では、貫通電極12をシリコン基板101の薄化後に形成した例を示したが、別の方法で形成することもできる。以下に、その製造手順について説明する。
