20120229003 | PIEZOELECTRIC DEVICE AND METHOD FOR MANUFACTURING THE SAME - In a piezoelectric device and a method of manufacturing thereof, after an ion implanted portion is formed in a piezoelectric single crystal substrate by implantation of hydrogen ions, an interlayer of a metal is formed on a rear surface of the piezoelectric single crystal substrate. In addition, a support member is bonded to the piezoelectric single crystal substrate with the interlayer interposed therebetween. A composite piezoelectric body in which the ion implanted portion is formed is heated at about 450° C. to about 700° C. to oxidize the metal of the interlayer so as to decrease the conductivity thereof. Accordingly, the conductivity of the interlayer is decreased, so that a piezoelectric device having excellent resonance characteristics is provided. | 09-13-2012 |
20130307372 | PIEZOELECTRIC DEVICE AND METHOD FOR MANUFACTURING PIEZOELECTRIC DEVICE - In a method of manufacturing a piezoelectric device, during an isolation formation step, a supporting substrate has a piezoelectric thin film formed on its front with a compressive stress film present on its back. The compressive stress film compresses the surface on a piezoelectric single crystal substrate side of the supporting substrate, and the piezoelectric thin film compresses the back of the supporting substrate, which is opposite to the surface on the piezoelectric single crystal substrate side. Thus, the compressive stress produced by the compressive stress film and that produced by the piezoelectric thin film are balanced in the supporting substrate, which causes the supporting substrate to be free of warpage and remain flat. A driving force that induces isolation in the isolation formation step is gasification of the implanted ionized element rather than the compressive stress to the isolation plane produced by the piezoelectric thin film. | 11-21-2013 |

20140191619 | PIEZOELECTRIC DEVICE AND METHOD FOR MANUFACTURING PIEZOELECTRIC DEVICE - In a method of manufacturing a piezoelectric device, among a +C plane on a +Z axis side of a piezoelectric thin film and a −C plane on a −Z axis side of the piezoelectric thin film, the −C plane on the −Z axis side of the piezoelectric thin film is etched. Thus, −Z planes of the piezoelectric thin film on which epitaxial growth is possible are exposed. Ti is epitaxially grown on the −Z planes of the piezoelectric thin film in the −Z axis direction such that the crystal growth plane thereof is parallel to the −Z planes of the piezoelectric thin film. Al is then epitaxially grown on the surface of the Ti electrode in the −Z axis direction such that the crystal growth plane thereof is parallel to the −Z planes of the piezoelectric thin film. | 07-10-2014 |
