1. A semiconductor device comprising:
an insulation layer;
a plurality of Fins arranged on the insulating film at a pitch smaller than a minimum pitch which includes a line and space pattern;
gate insulation films formed on sidewalls of the Fins;
a gate electrode which extends in a direction of arrangement of the Fins and which is electrically insulated from the plurality of Fins, the gate electrode being common in the plurality of Fins;
source-drain layers formed in portions of the Fins, the portions of the Fins being arranged on both sides of the gate electrode; and
a metal or a metal silicide which is in contact with upper surfaces or side surfaces of the source-drain layers of the plurality of Fins to connect the Fins to each other.
