Abstract
A semiconductor storage device includes a third semiconductor layer and a fourth semiconductor layer. The third semiconductor layer has a first width; the third semiconductor layer and a first insulating layer are disposed apart with a first distance; the third semiconductor layer and a second insulating layer are disposed apart with a second distance; the fourth semiconductor layer has a second width; the fourth semiconductor layer and the first insulating layer are disposed apart with a third distance; and the fourth semiconductor layer and the second insulating layer are disposed apart with a fourth distance. A shorter one of the first distance and the second distance is shorter than a shorter one of the third distance and the fourth distance, and the first width is larger than the second width.
