WIPO Patent Application WO/2021/003755

A1

Disclosed is a polished quartz crystal frequency wafer with a boss structure on an edge, the polished quartz crystal frequency wafer comprising an original wafer in the form of a rectangular block, with the boss structure being arranged on the original wafer, and the boss structure using any one of the following four kinds of structures: structure I: bosses connected to one another are arranged on the four side faces of the original wafer so as to form a rectangular quartz wafer (1); structure II: bosses are symmetrically arranged on two short side faces of the original wafer to form an H-steel-type short H-shaped quartz wafer; structure III: bosses are symmetrically arranged on two long side faces of the original wafer to form an H-steel-type long H-shaped quartz wafer; and structure IV: bosses are arranged mirrored on the upper bottom face and the lower bottom face of the original wafer to form a prism quartz wafer, wherein the prism quartz wafer comprises a plate wafer (7) with a length X, a width Y, and a height Z, the plate wafer (7) is the original wafer, bumps (8) in the form of a prism are arranged mirrored on the upper surface and the lower surface of the plate wafer (7), and the bumps (8) are located at the diagonal corners of the surface. The quartz crystal frequency wafer solves the problem of lamination.
