Abstract

In one embodiment, a semiconductor device includes a first film including a plurality of electrode layers and a plurality of insulating layers provided alternately in a first direction, and a first semiconductor layer provided in the first film via a charge storage layer and extending in the first direction. The device further includes a first conductive member provided in the first film and extending in the first direction, and a second semiconductor layer provided on the first film to contact the first semiconductor layer. The second semiconductor layer includes a first surface on a side of the first film, and a second surface on an opposite side of the first surface. The second surface is an uneven face protruding towards the first direction.
