Semiconductor devices

Abstract

[Problem] To provide a semiconductor device that improves operating speed and reliability. [Solution] A semiconductor device comprising: a source electrode; an insulator disposed above the source electrode; a first conductive layer in contact with the insulator in a first region; a second conductive layer disposed between the source electrode and the first conductive layer, and in contact with the insulator in a second region at a lower height from the source electrode than the first region; a first insulating layer disposed between the first conductive layer and the second conductive layer, and in contact with the insulator in a third region connecting the first region and the second region along a first direction; and a first columnar conductive portion disposed at the boundary between the first region and the third region, extending along a second direction orthogonal to the first direction, and connected to the first conductive layer.
