Abstract
A method to produce a piezoelectric device having one or more piezoelectric thin film layers and two or more electrode layers. The method comprises forming an amorphous electrode layer, forming a least one amorphous piezoelectric thin film layer over the amorphous electrode layer and forming a second electrode layer over at least one piezoelectric thin film layer. Then, the amorphous piezoelectric thin film layers and the amorphous electrode layers are crystallized by hydrothermal synthesis. The hydrothermal synthesis is not performed until all of the amorphous layers are deposited.
