    摘要: A semiconductor device in which the breakdown voltages of the cell unit and the guard ring can easily be matched, and the surge endurance of the device can be improved. This semiconductor device includes a guard ring region surrounding the cell diffusion layers which is formed from an array of a plurality of guard ring cells, where each of the guard ring cells is identical to each of the cell diffusion layers and the guard ring cells are electrically connected mutually, so that the diffusion depths of each of the cells of the guard ring region and the cell diffusion layers are identical, and consequently the breakdown voltages for the guard ring region and the cell diffusion layers can be made equal to each other.

    摘要: A semiconductor device includes a semiconductor substrate as a drain region. A metal source region is located on a first surface of the substrate. The metal and the substrate constitute a Schottky junction. An insulated gate, including a gate electrode and an insulating film surrounding the gate electrode, is adjacent to the Schottky junction, such that angle formed by the Schottky junction and the insulated gate in the substrate is an acute angle. A part of the Schottky metal can be buried in the form of a pillar in the substrate, and a channel region of the Schottky junction can be formed on the pillar near the insulated gate.
