Abstract
According to one embodiment, a method for manufacturing a nonvolatile storage device. The device includes a plurality of first conductive layers each extending in a first direction, a plurality of second conductive layers each extending in a second direction and spaced from the first layers, and memory cells each provided between the first layers and the second layers and including a rectifying element including a semiconductor layer, and a variable resistance element stacked with the rectifying element. The method includes a film formation step, a heating step and a patterning step. The film formation step is configured to form a rectifying element material film including an amorphous semiconductor film. The heating step is configured to heat the rectifying element material film. The patterning step is configured to form the rectifying element including the semiconductor layer by patterning the rectifying element material film after the heating step.
