Abstract
According to one embodiment, a semiconductor device includes a first electrode, a second electrode, a first region, a second region, a third region, a first conductive portion, a second conductive portion, a gate electrode, a first insulating portion, a second insulating portion, a third insulating portion, and a fourth insulating portion. The second electrode has a first portion and a second portion extending from the first portion toward the first electrode. The first region is between the first electrode and the second electrode. The second region is between the first region and the second electrode. The third region is between the second semiconductor region and the second electrode. The first conductive portion is in the first semiconductor region. The gate electrode is between the second region and the second portion. The second conductive portion is between the first conductive portion and the gate electrode.
