SEMICONDUCTOR DEVICE
First Claim
1. A semiconductor device comprising:
- a substrate;
a first conductive portion extending in a first direction perpendicular to a major surface of the substrate;
a second conductive portion extending in the first direction and provided to be separated from the first conductive portion along a second direction perpendicular to the first direction;
a semiconductor portion provided between the first conductive portion and the second conductive portion and including a first semiconductor region of a first impurity concentration and of a first conductive form;
a first electrode portion extending in the first direction between the first conductive portion and the second conductive portion;
a second electrode portion extending in the first direction between the first conductive portion and the second conductive portion and provided to be separated from the first electrode portion;
a first insulting portion provided between the first electrode portion and the semiconductor portion and having a first thickness in a normal direction of a boundary face of the first electrode portion; and
a second insulating portion provided between the second electrode portion and the semiconductor portion and having a second thickness greater than the first thickness in a normal direction of a boundary face of the second electrode portion.
