Piezoelectric thin film fabrication method,and ink jet recording head using saidfilm |
摘要 |
A piezoelectric thin film element is provided that functions well as an actuator, that yields the desired composition, and that exhibits good piezoelectric thin film distortion characteristics. A lower electrode 14 is formed on a substrate 10, a piezoelectric thin film precursor thin film layer is formed on the lower electrode, this is subjected to patterning, and a heating solution is applied to the substrate to implement hydrothermal processing, thereby selectively crystallizing the precursor thin film layer and yielding a piezoelectric thin film layer. <IMAGE> |
