ABSTRACT:
Piezoelectric devices and associated fabrication methods are disclosed. An exemplary piezoelectric device includes a piezoelectric vibrating piece having first and second electrodes and first and second surfaces, a glass base having first and second surfaces, and a lid. These three parts also form the device package. The first surface of the piezoelectric vibrating piece is mounted to the base, and the lid is mounted to the second surface of the piezoelectric vibrating piece to seal the package. The glass base includes first and second metal wires having ends that protrude from the surfaces of the base. The side surfaces of the protruding wire ends are connected to the first and the second electrodes, respectively. Manufacture is performed using whole wafers that are processed, sandwiched, bonded, and then cut to produce individual devices.
