Claim Text:
1. A semiconductor device comprising: a fin-shaped semiconductor layer on a semiconductor substrate; a first insulating film around the fin-shaped semiconductor layer; a first pillar-shaped semiconductor layer on the fin-shaped semiconductor layer; a first gate insulating film around the first pillar-shaped semiconductor layer and including a charge storing layer; a first control gate around the first gate insulating film, the first control gate extending in a direction perpendicular to the fin-shaped semiconductor layer; a second gate insulating film around the first pillar-shaped semiconductor layer and at a position higher than the first gate insulating film; a first selection gate around the second gate insulating film, the first selection gate extending in a direction perpendicular to the fin-shaped semiconductor layer; a fifth gate insulating film surrounding an upper portion of the first pillar-shaped semiconductor layer; and a first contact electrode surrounding and in intimate contact with the fifth gate insulating film and having an upper portion connected to an upper portion of the first pillar-shaped semiconductor layer; and a source line connected to an upper portion of the first pillar-shaped semiconductor layer and an upper portion of the first contact electrode and extending in a direction perpendicular to the fin-shaped semiconductor layer.
