Abstract:
1. A semiconductor device, comprising: a substrate; a stacked layer body provided above the substrate, the stacked layer body alternately stacking an insulator and an electrode film one on another; silicon pillars containing fluorine, the silicon pillar penetrating through and provided in the stacked layer body; a tunnel insulator provided on a surface of the silicon pillar facing to the stacked layer body; a charge storage layer provided on a surface of the tunnel insulator facing to the stacked layer body; a block insulator provided on a surface of the charge storage layer facing to the stacked layer body, the block insulator being in contact with the electrode film; and an embedded portion provided in the silicon pillars, the embedded portion contains fluorine and is composed of at least one selected from a silicon oxide film, a silicon nitride film, a silicon oxy-nitride film and a layered film having at least two selected from the silicon oxide film, the silicon nitride film and the silicon oxy-nitride film.
