Application Number: JP,2022-000594
Category (FI): H03H9/02@A,H03H9/19@A,H03H9/02@K
Stage: PROBLEM TO BE SOLVED: To provide a base for crystal vibrator having a novel structure utilizing inter-metal coupling and capable of reducing a mounting area by incorporating an input-side capacitor and an output-side capacitor.SOLUTION: A base 10 for crystal vibrator comprises a first substrate 20 and a second substrate 30 which are composed of glass or crystal. A second face 50 of the first substrate 20 and a first face 160 of the second substrate 30 are joined by inter-metal bonding, and at least one recess 100, which is recessed closer to both or one of the first substrate and the second substrate, is formed on a bonding interface. Two capacitors 110, which are used as an input or output-side capacitor of a crystal oscillator, are incorporated inside of the recess.SELECTED DRAWING: Figure 4 (Grant)
