Abstract
According to one embodiment, a semiconductor device includes: a stack body including an insulator, a first conductor and a second conductor stacked stepwise by interposing the insulator and electrically disconnected from each other; and a first contact plug which reaches the first conductor from a region above the stack body. The first conductor includes a first portion positioned below the insulator, a second portion positioned above the insulator, and a third portion that electrically connects the first portion of the first conductor and the second portion of the first conductor. The third portion of the first conductor is provided in an opening formed on the insulator.
