Classification: CPC H | IPC H

Claim 0:
1. A semiconductor device comprising a stacked body comprising a plurality of conductive layers and a plurality of first insulation layers alternately stacked in a first direction, wherein
the conductive layers each comprise:
a first metal layer comprising a first metal element and a substance that is chemically reactive with a material gas comprising the first metal element; and
a second metal layer comprising the first metal element and having a lower content of the substance than the first metal layer,

the first metal layer is disposed between the first insulation layers and the second metal layer,
the first metal layer further comprises nitrogen (N), and
within the first metal layer, a nitrogen concentration of the first metal layer is higher on a side near each of the first insulation layers than on a side near the second metal layer.
