IPC: H03H3/02
Filed: 1998-03-27
Abstract: PROBLEM TO BE SOLVED: To improve product yield when using a glass sealed ceramic package of high-accuracy articles by suppressing the increase in the CI value of an oscillator through suppressing the increase in the electrical resistance caused by the glass sealing temperature of a Cr/Au electrode film. SOLUTION: Cr base coating is applied to an exciting part on the crystal substrate of a glass-sealed ceramic package crystal oscillator, and an Au film is formed on that coating to form an Au electrode film. In such a filming method for electrodes for crystal oscillators, the thickness of the Cr base coating is less than 0.042 with respect to Au a film thickness, and the sheet resistirty of the Cr/Au electrode film is suppressed from becoming higher than 1 Ω/square or lower to increase the diffused solid concentration of Cr in the Au film, by applying heat treatment at the glass sealing temperature of from 350 to 400 deg.C.
