Patent ID: 8877578

Claim:
A semiconductor device comprising: a fin-shaped semiconductor layer on a semiconductor substrate and extending in a first direction; a first insulating film around the fin-shaped semiconductor layer; a pillar-shaped semiconductor layer on the fin-shaped semiconductor layer, a width of the pillar-shaped semiconductor layer, perpendicular to the first direction, being equal to a width of the fin-shaped semiconductor layer perpendicular to the first direction; a diffusion layer in an upper portion of the fin-shaped semiconductor layer and in a lower portion of the pillar-shaped semiconductor layer; a diffusion layer in an upper portion of the pillar-shaped semiconductor layer; a silicide in an upper portion of the diffusion layer in the upper portion of the fin-shaped semiconductor layer; a gate insulating film around the pillar-shaped semiconductor layer; a metal gate electrode around the gate insulating film; a metal gate line extending in a second direction perpendicular to the first direction of the fin-shaped semiconductor layer and connected to the metal gate electrode; a metal gate pad connected to the metal gate line, the width of the metal gate electrode and the width of the metal gate pad being larger than the width of the metal gate line; and a contact on the diffusion layer in the upper portion of the pillar-shaped semiconductor layer, wherein the diffusion layer in the upper portion of the pillar-shaped semiconductor layer is directly connected to the contact.
