Patent ID: 8914955

Claim:
A method for manufacturing a piezoelectric element, comprising: a process for forming a first conductive layer on a substrate; a process for forming a piezoelectric layer having a region serving as an active region on the first conductive layer; a process for forming a second conductive layer, which overlaps with the region, on the piezoelectric layer; a process for forming a third conductive layer, which overlaps with the region, on the second conductive layer; a process for forming an opening portion that divides the third conductive layer into a first portion and second portion in the third conductive layer above the region; a process for forming a resist layer that covers the opening portion and a peripheral portion at the side of the opening portion of the first portion and the second portion; a process for etching the third conductive layer using the resist layer to form a first conductive portion and a second conductive portion; and a process for etching the second conductive layer using the resist layer to form a third conductive portion.
