Abstract:
According to one embodiment, a method for manufacturing a semiconductor device includes forming a first metal material inside the first holes; forming a plurality of metal layers on the first region, the metal layers being stacked with an insulator interposed, the metal layers including a plurality of terrace portions arranged in a staircase configuration with a level difference; forming a second insulating layer on the first insulating layer and on the terrace portions; simultaneously forming a second hole and a plurality of third holes piercing the second insulating layer, the second hole reaching the first metal material, the third holes reaching the terrace portions; and forming a second metal material inside the second hole and inside the third holes.

Claim (Index 16):
A semiconductor device, comprising:\n a substrate; a stacked body provided on the substrate, the stacked body including a plurality of metal layers stacked with an insulator interposed, the metal layers including a plurality of terrace portions arranged in a staircase configuration with a level difference; a semiconductor body extending through the stacked body in a stacking direction of the stacked body; a charge storage portion provided between the semiconductor body and one of the metal layers; a transistor including an active region and a gate electrode, and being provided in a region of the substrate separated from the stacked body; a first insulating layer covering the transistor; a second insulating layer provided on the first insulating layer and on the terrace portions; a plurality of first contacts extending through the first insulating layer in the stacking direction, being connected to the active region and the gate electrode, and including a metal; a plurality of second contacts extending through the second insulating layer in the stacking direction, being connected to the first contacts, and including a metal; and a plurality of third contacts extending through the second insulating layer in the stacking direction, being connected to the terrace portions, and including a metal, a diameter of an upper end of one of the first contacts being larger than a diameter of a lower end of one of the second contacts, a level difference being formed between a side surface of one of the first contacts and a side surface of one of the second contacts at a connection portion between the one of the first contacts and the one of the second contacts.
