Abstract
A semiconductor storage element according to the present embodiment includes a laminated body, a semiconductor layer, a first insulator, a second insulator, a third insulator, and a fourth insulator. In the laminated body, the insulating layers and conductive layers are alternately laminated in a first direction. The third insulator is disposed between the laminated body and the second insulator. A first part of the fourth insulator is disposed between each of the conductive layers and the third insulator. The average concentration of deuterium in the first part is higher than the average concentration of deuterium in the third insulator. The ratio of deuterium concentration to light hydrogen concentration in the first part is smaller than the ratio of deuterium concentration to light hydrogen concentration in the third insulator.
