摘要: A silicon carbide semiconductor device includes: a semiconductor substrate including first and second gate layers, a channel layer, a source layer, and a trench; a gate wiring having a first portion and a plurality of second portions; and a source wiring having a third portion and a plurality of fourth portions. The trench extends in a predetermined extending direction. The first portion connects to the first gate layer in the trench, and extends to the extending direction. The second portions protrude perpendicularly to be a comb shape. The third portion extends to the extending direction. The fourth portions protrude perpendicularly to be a comb shape, and electrically connect to the source layer. Each of the second portions connects to the second gate layer through a contact hole.
