Method of manufacturing a piezoelectric tuning fork resonator |
摘要 |
A piezoelectric tuning fork resonator having a piezoelectric substrate provided with a stepped portion on its end and a tuning fork arm portion formed in the stepped portion. A dummy substrate is arranged adjacent to a side of the piezoelectric substrate and a pair of sealing substrates are pasted onto upper and lower portions of the piezoelectric substrate and the dummy substrate to form a chip type piezoelectric tuning fork resonator. In another embodiment, the piezoelectric substrate includes a resin sealing portion having a hollow portion defined around the tuning fork arm portion so as to form a resin-coated piezoelectric tuning fork resonator.
