Abstract
A piezoelectric device package consists of a base and a cover which are sealed together to hermetically seal a piezoelectric device such as a quartz crystal therebetween. A recess in the cover receives the quartz crystal. Feedthrough holes in the base, or the cover, or both, which have electrostatic seals formed over them provide a means for making electrical connections with the quartz wafer while still maintaining the hermetic seal.
