    Abstract: A crystal vibration device comprising a crystal diaphragm formed on the opposite main surfaces thereof with exciting electrodes and extraction electrodes extracted from respective exciting electrodes, and an electrode pad formed on a base and electrically connected with the crystal diaphragm via a silicon-based conductive adhesive. Each of at least extraction electrodes, out of the exciting electrodes and the extraction electrodes, comprises a Cr film layer, an Au film layer, and a Cr thin film layer or an Ag thin film layer sequentially laminated on the crystal diaphragm. The electrode pad comprises a tungsten- or molybdenum-made metallized layer, a Ni film layer and an Au film layer sequentially laminated on the base, and at least a specified region, to which a silicon conductive adhesive is applied, in the Au film layer of the electrode pad is diffused with Ni in the Ni film layer.

    Abstract: A piezoelectric resonator device having a sandwich structure is provided, which can avoid gas generation and reduce the size or height. A crystal resonator 101 includes a crystal resonator plate 2, a first sealing member 3 and a second sealing member 4. A sealing-member-side first bonding pattern 321 and a sealing-member-side second bonding pattern 421, both to be bonded to the crystal resonator plate 2, are formed respectively on the first sealing member 3 and the second sealing member 4. On the crystal resonator plate 2, a resonator-plate-side first bonding pattern 251 to be bonded to the first sealing member 3 is formed on a first main surface 211 and a resonator-plate-side second bonding pattern 252 to be bonded to the second sealing member 4 is formed on a second main surface 212. The sealing-member-side first bonding pattern 321 is bonded to the resonator-plate-side first bonding pattern 251, and the sealing-member-side second bonding pattern 421 is bonded to the resonator-plate-side second bonding pattern 252, both by diffusion bonding.

    Abstract: PROBLEM TO BE SOLVED: To provide a piezoelectric vibration device which improves hermetic sealing performance of a package and facilitates the characteristic improvements.SOLUTION: In a surface mounted crystal oscillator, a crystal diaphragm 2 is housed in a base and is hermetically sealed by a lid and an IC 4 for an oscillation circuit is mounted. The base has a cavity C opening at the lower side. A step part 111 is formed into a rectangular peripheral shape in the cavity so as to be spaced a given depth dimension away from the opening of the cavity C. The lid is joined to the upper surface of the step part by a brazing material 31. A lower portion (the opening side) 11a of a side wall part 11 is formed so as to be thinner than the step part, and external terminals 14 are formed at four corners of a base bottom surface.

    Abstract: PROBLEM TO BE SOLVED: To provide a highly reliable piezoelectric oscillation device by improving impact resistance. SOLUTION: An elastic support having a buffer function in a three-dimensional direction is bonded to a base. On the holding part of the elastic support, a piezoelectric vibration plate is loaded in a flat state in the state that the main surface of both short sides of it is held. A conductive bonding material S is applied to the diagonal position of both short sides of the piezoelectric vibration plate, and is conductively bonded with the elastic support. Relative to the short side length W of the piezoelectric vibration plate, the length Ws of the conductive bonding material is set to the length of about 30%. COPYRIGHT: (C)2010,JPO&INPIT
