    Abstract: A semiconductor dynamic quantity sensor has a substrate including a semiconductor substrate, an insulation layer on a main surface of the semiconductor substrate, and a semiconductor layer on the insulation layer. The main surface has a projection that is trapezoidal or triangular in cross section. The semiconductor layer is divided by a through hole into a movable portion. A tip of the projection is located directly below the movable portion and spaced from the movable portion by a predetermined distance in a thickness direction of the substrate. A width of the tip of the projection is less than a width of the movable portion in a planar direction of the substrate. The distance between the tip of the projection and the movable portion is equal to a thickness of the insulation layer.

    Abstract: A vibrating gyrosensor includes a support substrate on which a wiring pattern having a plurality of lands is formed, and a vibrating element mounted on a surface of the support substrate. The vibrating element includes a base part having a mounting surface on which a plurality of terminals, and a vibrator part integrally projected in a cantilever manner from one of the sides of the base part and having a substrate-facing surface coplanar with the mounting surface of the base part. The vibrator part has a first electrode layer, a piezoelectric layer, and a second electrode layer, which are formed on the substrate-facing surface in that order. Furthermore, a reinforcing part is formed at the base end of the vibrator part so that the sectional area of the vibrator part gradually increases toward the base part.

    Abstract: A monolithic micro or nano electromechanical transducer device includes a pair of substrates (20, 25) respectively mounting one or more elongate electrical conductors (40) and resilient solid state hinge means (30, 32) integral with and linking the substrates to relatively locate the substrates so that respective elongate electrical conductors (40) of the substrates are opposed at a spacing that permits a detectable quantum tunnelling current between the conductors when a suitable electrical potential difference is applied across the conductors. The solid state hinge means permits relative parallel translation of the substrates transverse to the elongate electrical conductors.
