Abstract:
According to one embodiment, a stacked body includes a plurality of electrode layers stacked with an insulator interposed. A conductive via pierces the stacked body, and connects an upper layer interconnect and a lower layer interconnect. A insulating film is provided between the via and the stacked body. A distance along a diametral direction of the via between a side surface of the via and an end surface of one of the electrode layers opposing the side surface of the via is greater than a distance along the diametral direction between the side surface of the via and an end surface of the insulator opposing the side surface of the via.
