Abstract
An oscillator piezoelectric structure includes a piezoelectric material having a surface and an interior. A plurality of patterned processing zones are formed on the surface and in the interior of the piezoelectric material, and the patterned processing zones include a material removal area and a material modification area. Therefore, without changing the appearance of the piezoelectric material, the patterned processing zones on the piezoelectric material can accurately adjust the frequency of the oscillator and block unnecessary modes at the same time.
