Patent ID: 7200907

Claim:
A method of manufacturing a piezoelectric device, the method comprising: forming an insulating layer over a substrate; forming a buffer layer on the insulating layer by providing an atom of metal material to the insulating layer and irradiating the insulating layer with an ion beam, the buffer layer including the atom of metal material; forming a first electrode on the buffer layer by providing an atom of strontium ruthenate to the buffer layer and irradiating the buffer layer with an ion beam, the first electrode including the atom of strontium ruthenate; forming a piezoeletrie layer on the first electrode by providing a mist to form a precursor film of the piezoeletric layer on the first electrode and irradiating the precursor film with an ion beam, the mist including a piezoeletric material of which the piezoeletric layer is composed; and forming a second electrode over the piezoeletric layer.
