Title: Metal film forming mask, crystal wafer, and crystal resonator manufactured by using these
Inventor: YAMAMOTO IZUMI
IPC: C23C14/04
Filed: 2003-02-21
Abstract: <P>PROBLEM TO BE SOLVED: To provide a metallic film forming mask and a crystal wafer for forming a frequency adjusting metal film having a uniform shape, and a uniform film thickness conforming to targets on a crystal resonator; and also to provide a crystal resonator for which a manufacturing cost is suppressed.  <P>SOLUTION: The material for the metal film forming mask 1 is a crystal. Since the mask 1 is of the same material as that of the crystal wafer, deviation due to thermal expansion is eliminated, and the shape and the thickness of the frequency adjusting metal film becomes uniform and the profile of the resonance frequency of the crystal resonator decreases. In this way, a conventional defect can be solved in which a frequency adjusting metal film is deformed due to thermal expansion because a metal film forming mask is heated in forming the frequency adjusting metal film of a crystal resonator, a crystal wafer shifts from the metal film forming mask and a gap is formed, and the frequency adjusting metal film to be formed has a large variation in shape and thickness.  <P>COPYRIGHT: (C)2004,JPO&NCIPI
