Abstract
According to one embodiment, the semiconductor device is provided with a first semiconductor layer, a second semiconductor layer, a third semiconductor layer, a pair of first conductors, a pair of second conductors, first wiring layers, and second wiring layers. Each pair of first and second conductors is formed in first and second trenches via the first and second insulating films and is opposite to the first semiconductor layer and the second semiconductor layer. The first wiring layers have main body parts and plural convex parts. Plural convex parts extend from the main body parts and are electrically connected with the first conductors via a first opening part of a first interlayer insulating film. The second wiring layers are electrically connected with the second conductors via a second opening part of the first interlayer insulating film.
