ABSTRACT:
A surface mount crystal oscillator comprises a crystal blank, an IC chip having an oscillation circuit integrated thereon, and a hermetic package for accommodating the crystal blank and IC chip therein. The hermetic package comprises a substantially rectangular ceramic substrate formed with a metal film which makes a round on one main surface thereof, and a concave metal cover having an open end face bonded to the metal film. The IC chip is secured to the one main surface of the ceramic substrate through ultrasonic thermo-compression bonding using bumps, the crystal blank is disposed above the IC chip, and the ceramic substrate has the one main surface formed as a flat surface.
