Patent ID: 8193571

Claim:
A nonvolatile semiconductor memory device comprising: a stacked body in which a plurality of insulating films and a plurality of electrode films are alternately stacked and a through-hole is formed to extend in the stacking direction; a semiconductor pillar filled into the through-hole; a charge storage layer provided between the electrode film and the semiconductor pillar; an insulative block layer provided between the electrode film and the charge storage layer; and an insulative tunnel insulation layer provided between the semiconductor pillar and the charge storage layer, a gap being formed between the electrode films to connect with the through-hole, the charge storage layer being formed along an inner face of the gap, and the formula ( tb+tc )×2 <S< ( tb+tc+tt )×2 (1) being satisfied, where S is a distance between the electrode films, tb is a thickness of the block layer, tc is a thickness of a charge storage layer, and tt is a thickness of the tunnel insulation layer.
