Abstract
According to one embodiment, a substrate includes a first portion and a second portion. The first portion has a columnar configuration. The second portion has an upper surface continuous with a side surface of the first portion via a corner. A plurality of electrode layers include a lowermost electrode layer opposing the side surface of the first portion above the second portion. An insulating film is provided between the side surface of the first portion and a side surface of the lowermost electrode layer, and between the upper surface of the second portion and a lower surface of the lowermost electrode layer. An angle formed between the upper surface of the second portion and the corner of the substrate on the insulating film side is greater than 90°.
