摘要： A method of manufacturing a thin quartz crystal wafer from a quartz crystal block which is cut from a crystal body of synthetic quartz crystal and has a flat principal surface, comprises the steps of (a) converging a laser beam at a region in said quartz crystal block at a predetermined depth from the principal surface thereof to cause multiphoton phenomenon state, thereby breaking Si—O—Si bonds of quartz crystal in said region to form voids in said region, and (b) peeling said thin quartz crystal wafer from a body of said quartz crystal block along said voids. The above process is repeatedly performed on one quartz crystal block to peel off a plurality of thin quartz crystal wafers successively from the principal surface of the quartz crystal block. Each of the thin quartz crystal wafers is divided into individual quartz crystal blanks for making quartz crystal units.

摘要： Excitation electrodes are respectively affixed to central portions of both surfaces of a long plate-shaped AT-cut crystal resonator, the central portion starts a thickness shear oscillation in the length direction of the crystal resonator when an electric signal is applied to the central portion of the crystal resonator through the excitation electrodes. And, channel-shaped, half-circular-shaped, or trapezoid grooves in cross-section are respectively formed in the plate width direction on middle portions between the center portion and end portions of the crystal resonator. These grooves are formed so as to be symmetrical with respect to a thicknesswise central position of the crystal resonator through a well-known etching technique such as photo-etching and the like.
