SEMICONDUCTOR DEVICE AND METHOD FOR MANUFACTURING SAME

摘要

The purpose of the present invention is to provide a semiconductor device that is provided with a terminal region where electric field concentration can be effectively relaxed, while suppressing resist collapse during manufacture, and to provide a method for manufacturing the semiconductor device. This semiconductor device is provided with: a semiconductor element (110) formed on a semiconductor substrate formed of a first conductivity-type wide-band-gap semiconductor; and a plurality of second conductivity-type ring-like regions (2), which are formed on the semiconductor substrate (1) by surrounding the semiconductor element (110) in a planar view. At least one of the ring-like regions (2) is provided with one or more separating regions (5) that make the inner side and the outer side of the ring-like region (2) communicate with each other in a planar view.
