ABSTRACT:
A quartz crystal resonator adapted to resonate in the thickness shear mode has a wafer with a sculptured recessed portion on at least one surface. The recessed portion can be exceptionally thin without loss of structural integrity to produce relatively high frequency fundamental crystals. A novel apparatus is used to machine the central portion of the major surface of the flat wafer to form a recessed portion.
