[0002] A crystal oscillator wafer is an electronic component made using the piezoelectric effect of quartz crystals, mainly used for rate and thickness sensing elements in film thickness control instrument systems. The crystal oscillator wafer is derived from a polyhedral quartz rod, which is cut, ground and processed into a thin wafer, usually 0.23mm thick and 13.98mm in diameter. After each wafer is trimmed, polished and cleaned, a full metal electrode is plated on the front surface, and a keyhole-shaped electrode is plated on the back surface.

[0003] The working principle of the crystal oscillator wafer is based on the piezoelectric effect of quartz crystals. When an electric field is applied to the two electrodes of the quartz crystal, the crystal will deform mechanically, which is called the piezoelectric effect. Conversely, if mechanical pressure is applied to the two ends of the crystal, the crystal will generate an electric field. This conversion process between mechanical energy and electrical energy makes the crystal produce mechanical vibration under the action of alternating voltage, and mechanical vibration also produces alternating electric field.
