20140203883 | RESONATOR, OSCILLATOR, AND METHOD FOR FABRICATING OSCILLATOR - A resonator includes a ring-shaped or disk-shaped resonator main body, a supporting joist, and a securing portion. The supporting joist extends from the resonator main body to support the resonator main body. The securing portion is formed at a distal end of the supporting joist and the securing portion is secured to a base material. The securing portion includes a first rod-shaped portion and a second rod-shaped portion. The first rod-shaped portion is formed in a first direction. The second rod-shaped portion is formed in a second direction different from the first direction. | 07-24-2014 |
20140290019 | METHOD FOR FABRICATING VIBRATOR - A method for fabricating a vibrator with a vibrating plate and an electrode for vibrating the vibrating plate includes laminating, forming, filling-in, patterning, subsequently laminating, and subsequently etching. The forming forms a through hole that passes through a conductive film and a second sacrifice film and reaches at least a middle portion in a film thickness direction of a first sacrifice film. The filling-in fills in an auxiliary film for adjusting temperature characteristics including silicon and oxygen from a lower end position to an upper end position of the through hole. The subsequently etching etchs an upper end portion of the auxiliary film, a lower end portion of the auxiliary film, the first sacrifice film, the second sacrifice film, and a third sacrifice film, while leaving the auxiliary film inside the through hole on the vibrating plate, with a use of an etching fluid including hydrogen fluoride. | 10-02-2014 |
