METHOD OF MANUFACTURING CRYSTAL-PLATE

摘要

A method of manufacturing a crystal plate is provided to prevent the stress of the crystal plate due to a mechanical impact by forming inclined surfaces at both ends of the crystal plate through a chemical reaction. A method of manufacturing a crystal plate includes the steps of: preparing the chip-sized crystal plate having a first surface and a second surface opposite to the first surface; forming a metal film for a beveling process so as to expose some area of the first and second surfaces adjacent to both ends of the chip-sized crystal plate; and performing the beveling process by selectively etching the exposed crystal plate.
