Description
かかる本発明では、各開口部に対応する領域の不連続金属層が同電位となることで、流路形成基板をエッチングする際に、密着層の表層に変質層が形成されるのを防止することができる。したがって、ニッケルクロムからなる密着層をウェットエッチングによって良好に除去することができ、貫通部を良好に形成することができる。
(実施形態1)
図1は、本発明の実施形態1に係る製造方法によって製造されるインクジェット式記録ヘッドの分解斜視図であり、図2は、図1の平面図及び断面図である。図示するように、流路形成基板10は、本実施形態では面方位(110)のシリコン単結晶基板からなり、その一方の面には予め熱酸化によって二酸化シリコンからなる厚さ0.5〜2μmの弾性膜50が形成されている。
以上、本発明の実施形態を説明したが、本発明は、上述した実施形態に限定されるものではない。例えば、上述の実施形態では、接合基板としてリザーバ部を有するリザーバ形成基板を例示したが、接合基板は特に限定されるものではなく、流路形成基板に形成された第2の貫通孔に連通する第2の貫通孔を有する基板であればよい。さらに言えば、上述の実施形態では、貫通部としてリザーバ、位置決め孔、貫通溝を例示したが、貫通部は、これらに限定されるものではなく、流路形成基板を貫通する第2の貫通孔と接合基板を貫通する第1の貫通孔とで構成されるものであればよい。
