Patent ID: 8759938

Claim:
A semiconductor device, comprising: an element region; a junction-termination region, the junction-termination region surrounding the element region; a first semiconductor region of a first conductivity type that is placed in the element region and the junction-termination region; a second semiconductor region of the first conductivity type that is placed above the first semiconductor region; a plurality of pillars of a second conductivity type, the plurality of pillars forming an array of pillars, the array spanning at least portions of the element region and the junction-termination region in a first direction, the pillars extending from an upper surface of the second semiconductor region into the second semiconductor region in a direction substantially perpendicular to a plane containing the first semiconductor region; a plurality of field plate electrodes that are arrayed in the first direction, the plurality of field plate electrodes above the plurality of pillars, the plurality of field plate electrodes separated from the plurality of pillars by an insulating film; and a shield electrode that is electrically connected to a drain potential, the shield electrode located above at least one of the plurality of field plate electrodes.
