Description
まず、図1(A)に示すように、シリコンで形成された基板1を用意した。基板1の第一面側には、TaSiNからなるエネルギー発生素子2が複数形成されており、エネルギー発生素子2の間には、アルミニウムからなる犠牲層7が形成されている。エネルギー発生素子2は不図示の配線等によってエネルギー発生素子を駆動させる半導体素子に接続されており、エネルギー発生素子2と犠牲層7とは、SiNからなる絶縁層3で覆われている。基板1の第二面側には、SiO2からなる保護層4が設けられている。
実施例1において、図3(A)に示すステージを用いたのに対し、実施例2においては、図3(B)に示すステージを用いた。これ以外は実施例1と同様にした。
