    摘要： Monolithic integrated device having an architecture that allows an acoustic device to transduce either surface acoustic waves or bulk acoustic waves, comprising: a substrate layer being the base of the device; an inter-layer dielectric disposed on top of the substrate layer; an electronic circuitry substantially formed in the inter-layer dielectric and supported by the substrate layer, the electronic circuitry comprises a plurality of metal layers; and a piezoelectric layer being sandwiched between a top electrode and a bottom electrode within the inter-layer dielectric. The top electrode is an upper metal layer belonging to the electronic circuitry and the bottom electrode is a lower metal layer belonging to the electronic circuitry. To transduce the bulk acoustic waves, the inter-layer dielectric is formed with a top cavity above the top electrode and a bottom cavity below the bottom electrode.

    摘要： A surface mount type quartz crystal device according to a first aspect of the disclosure includes a ceramic package, a pedestal blank, a quartz-crystal vibrating piece. The pedestal blank is placed within the ceramic package via a conductive adhesive. The quartz-crystal vibrating piece is placed on the pedestal blank. The conductive adhesive is formed along an outer peripheral side of the pedestal blank so as to avoid overlap with the excitation electrode viewed in a normal direction of the excitation electrode. The pedestal blank is formed to avoid a region where a distance from the quartz-crystal vibrating piece is equal to or smaller than a size of a clearance between the pedestal blank and the quartz-crystal vibrating piece at the outer peripheral side, in a region where the excitation electrode faces at the pedestal blank side viewed in the normal direction.

    摘要： The invention concerns microelectromechanical resonators. In particular, the invention provides a resonator comprising a support structure, a doped semiconductor resonator suspended to the support structure by at least one anchor, and actuator for exciting resonance into the resonator. According to the invention, the resonator comprises a base portion and at least one protrusion extending outward from the base portion and is excitable by said actuator into a compound resonance mode having temperature coefficient of frequency (TCF) characteristics, which are contributed by both the base portion and the at least one protrusion. The invention enables simple resonators, which are very well temperature compensated over a wide temperature range.

    摘要： A piezoelectric oscillation element (1) comprising a piezoelectric substrate (10), a first conductor film (21) formed on one main surface of the piezoelectric substrate (10), a second conductor film (22) formed on the other main surface, and grounding terminals (31a, 31b) formed on the side surfaces of the piezoelectric substrate (10). Specified capacitances are respectively formed between the first and second conductor films (21, 22) formed on the main surfaces of the piezoelectric substrate (10) and the grounding terminals (31a, 31b) formed on the side surfaces thereof. Larger capacitances can be formed than when electrodes are disposed on the same main surface in proximity of each other to form a capacitance, whereby no adverse effect is given to thickness vibration occurring between the first and second conductor films (21, 22).
