Abstract:
According to an embodiment, a non-volatile storage device includes a first layer, a second layer formed on the first layer, a stacked body including a plurality of conductive films stacked on the second layer, and a semiconductor pillar which penetrates the stacked body and the second layer and reaches the first layer. The semiconductor pillar includes a semiconductor film formed along an extending direction of the semiconductor pillar, and a memory film which covers a periphery of the semiconductor film. The memory film includes a first portion formed between the stacked body and the semiconductor film and a second portion formed between the second layer and the semiconductor film. An outer periphery of the second portion in a plane perpendicular to the extending direction is wider than an outer periphery of the first portion on a second layer side of the stacked body.

Claim (Index 20):
The method of  claim 14 , wherein in the forming a memory hole expansion layer, a solution obtained by mixing 2-hydroxy ethyl tri-methyl ammonium hydroxide, hydrogen peroxide and water is used for selectively etching the memory hole expansion preparation layer.
