Abstract:
1. A method for manufacturing a piezoelectric device including a piezoelectric thin film and a support member supporting the piezoelectric thin film, comprising: an ion implantation step of forming an ion implantation layer by implanting ions into a piezoelectric substrate; a sacrificial layer formation step of forming a sacrificial layer on the surface of the piezoelectric substrate at an ion implantation layer side of the sacrificial layer; a support member formation step of forming the support member on the surface of the piezoelectric substrate at the ion implantation layer side; a peeling step of forming the piezoelectric thin film by peeling a portion of the piezoelectric substrate in which the ion implantation layer is formed; and a sacrificial layer removal step of removing the sacrificial layer.
