Abstract

PURPOSE:To lower prices and improve productivity by making the vibrating part of a crystal resonator vibrating at vertical vibration mode to a shape of less than 7 mm in maximum length, less than 1.5 mm in maximum width and making the crystal resonator from a flat crystal plate of less than 0.2 mm in thickness through photoetching.
