  • Patent number: 10770581
    Abstract: A first side wall and a second side wall of a trench are each an a-plane having high carrier mobility. Along the first side wall of the trench, a gate insulating film is provided. A gate electrode is provided in the trench, and across the gate insulating film, opposes a portion of a p-type base region between an n+-type source region and an n-type current spreading region. Along the second side wall of the trench, a conductive layer is provided. The conductive layer, at the second side wall of the trench, forms Schottky contacts with a p++-type contact region, the p-type base region, and the n-type current spreading region. The trench has a bottom corner portion that is at the second side wall and encompassed by a p+-type region that is provided in the n-type current spreading region so as to be separated from the p-type base region.

  • Patent number: 10591922
    Abstract: Arrangements related to operating an autonomous vehicle in view-obstructed environments are described. At least a portion of an external environment of the autonomous vehicle can be sensed to detect one or more objects located therein. An occupant viewable area of the external environment can be determined. It can be determined whether one or more of the detected one or more objects is located outside of the determined occupant viewable area. Responsive to determining that a detected object is located outside of the determined occupant viewable area, one or more actions can be taken. For instance, the action can include presenting an alert within the autonomous vehicle. Alternatively or in addition, the action can include causing a current driving action of the autonomous vehicle to be modified.
