Claim 8:
9. A method for polarizing a piezoelectric film, comprising:
forming a piezoelectric film on an even surface of a conductive substrate, wherein forming the piezoelectric film on the even surface of the conductive substrate comprises flat adhering the piezoelectric film on the even surface of the conductive substrate to make an adhesion surface of the piezoelectric film being in contact with the even surface of the conductive substrate, wherein flat adhering the piezoelectric film to the even surface of the conductive substrate comprises generating static electricity on the adhesion surface of the piezoelectric film, and generating the static electricity on the adhesion surface of the piezoelectric film comprises using a pressurized gas to blow the adhesion surface, and the adhesion surface of the piezoelectric film is adhered to the even surface of the conductive substrate by an electrostatic adsorption method; and
performing a polarization process on the piezoelectric film while the piezoelectric film is flat adhered to the even surface of the conductive substrate.
