Abstract:
According to an embodiment, a semiconductor storage device includes a substrate. A stack is provided above the substrate, and includes a resistance change element and a metal layer provided above the resistance change element. A first insulating layer is provided on a side surface of the stack. A second insulating layer is provided on the first insulating layer. And an electrode is provided on the metal layer and on the first insulating layer so as to extend along a stacking direction in the second insulating layer. A lower surface of the electrode as viewed in the direction has a diameter greater than a diameter of an upper surface of the stack as viewed in the direction. A lowermost portion of the electrode is at a same level as an uppermost portion of the metal layer as viewed in the direction.

Claim (Index 7):
The method according to  claim 6 , wherein\n an ion beam angle used in the etching is equal to or lower than a first angle relative to a stacking direction, and an etching rate of the metal layer is equal to or higher than an etching rate of the first insulating layer when the ion beam angle is equal to or lower than the first angle.
