Description
本実施の形態のインクジェット式記録ヘッドは、ノズル開口部に連通する圧力発生室の一部を構成する弾性膜と、端部が弾性膜に接続され、中央部は弾性膜と空隙を介して対向し、下部電極、圧電膜、上部電極が積層された圧電積層部とを備える。
本実施の形態のインクジェット式記録ヘッドは、弾性膜の段差部の構造が第1の実施の形態と異なっている。段差部の構造以外は第1の実施の形態と同様であるので、第1の実施の形態と重複する内容については、記載を省略する。
圧電膜52に加わる応力と弾性膜30に生じる撓みの関係について、シミュレーション結果に基づきさらに詳細に説明する。図1、2に示す第1の実施の形態と同様の構造を備えるインクジェット式記録ヘッドについて、シミュレーションを行った。シミュレーションに使用したインクジェット式記録ヘッドの主要部寸法を表1に示す。圧電膜52としては、c軸配向性の良い窒化アルミニウム(AlN)を、使用した。また、上下電極51、下部電極53として白金(Pt)を、弾性膜30として酸化シリコン(SiO2)を使用した。
次に、比較例1として、従来のユニモルフ構造を持つインクジェット式記録ヘッドについても同様にシミュレーション結果を示し、実施例と詳細に比較した。
次に、比較例2として、段差を持つ弾性膜とユニモルフ構造を持つインクジェット式記録ヘッドについても同様にシミュレーション結果を示し、実施例と詳細に比較した。
図16は、比較例2における1つの圧力発生室の横手方向における断面構造を示す図である。実施例と同じ部材には同じ番号を付してある。
