Abstract:
1. A semiconductor device, comprising: a fin-shaped semiconductor layer formed on a semiconductor substrate, said fin-shaped semiconductor layer extending in a first direction and having a given width; a first insulating film formed around said fin-shaped semiconductor layer; a pillar-shaped semiconductor layer formed on said fin-shaped semiconductor layer and having a width equal to the given width of said fin-shaped semiconductor layer; a gate insulating film formed around said pillar-shaped semiconductor layer; a gate electrode formed around said gate insulating film; a gate line connected to said gate electrode, extending in a second direction perpendicular to said first direction of said fin-shaped semiconductor layer, and formed, as a sidewall-shape, on a side wall of a dummy gate formed of a polysilicon; a first diffusion layer formed in an upper portion of said pillar-shaped semiconductor layer; and a second diffusion layer formed over an upper portion of said fin-shaped semiconductor layer and a lower portion of said pillar-shaped semiconductor layer.
