    Abstract: A semiconductor device includes a substrate, a semiconductor layer, an element region, and fin transistors. The substrate includes a principal surface. The semiconductor layer is formed as a surface layer or on the principal surface of the substrate, the surface layer being the principal surface of the substrate. The semiconductor layer has a crystal structure in which an angle between two of crystal orientations with equivalent relationships on a crystal plane having a correspondence with the principal surface of the substrate is 60 degrees or 120 degrees. The element region includes unit element regions formed on the principal surface of the substrate. The fin transistors are formed in the semiconductor layer, in the respective unit element regions. The fin transistors radially extend from a center toward an outer periphery of the element region. Adjacent two of the fin transistors have a spacing with a 60° angle or a 120° angle.

  • Publication number: 20200339075
    Abstract: Provided is a manual release mechanism for a parking lock device including a gear, a meshing tooth capable of meshing with the gear, and an actuator that switches between a parking lock state and a non-parking lock state. The manual release mechanism includes an outer lever, an elastic member, and a retaining member. An activation state of the parking lock device is switched by the outer lever. One end of the elastic member is mounted on the outer lever. The retaining member has the other end of the elastic member mounted thereon, and retains the outer lever in a turning position through the elastic member. The elastic member is mounted between the outer lever and the retaining member so as to exert a force in the direction of a tangent to a turning locus of the outer lever when the outer lever is not being manually operated by the driver.
