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 second pillar-shaped semiconductor layer on the fin-shaped semiconductor layer; a metal contact electrode around the second pillar-shaped semiconductor layer; a metal contact line extending in a direction orthogonal to the fin-shaped semiconductor layer and connected to the metal contact electrode; a third diffusion layer in an upper portion of the fin-shaped semiconductor layer and in a lower portion of the second pillar-shaped semiconductor layer, the contact electrode connected to the third diffusion layer; a fourth contact surrounding an upper side wall of the second pillar-shaped semiconductor layer and connected to the contact electrode; and a fifth contact connecting an upper portion of the fourth contact to an upper portion of the second pillar-shaped semiconductor layer.
