Claim Text:
1. A semiconductor device comprising: a fin-shaped silicon layer on a silicon substrate; a first insulating film around the fin-shaped silicon layer; a pillar-shaped silicon layer on the fin-shaped silicon layer; a gate insulating film around the pillar-shaped silicon layer; a gate electrode around the gate insulating film; a gate line connected to the gate electrode and extending in a direction orthogonally intersecting the fin-shaped silicon layer; a first diffusion layer in an upper portion of the pillar-shaped silicon layer; a second diffusion layer in an upper portion of the fin-shaped silicon layer and a lower portion of the pillar-shaped silicon layer; a first silicide in an upper portion of the first diffusion layer; a first metal wire on the first silicide; and a nitride film sidewall around a sidewall of an upper portion of the pillar-shaped silicon layer.
