    摘要: A semiconductor device which includes fins of a semiconductor material formed on a semiconductor substrate and then a gate electrode formed over and in contact with the fins. An insulator layer is deposited over the gate electrode and the fins. A trench opening is then etched in the insulator layer. The trench opening exposes the fins and extends between the fins. The fins are then silicided through the trench opening. Then, the trench opening is filled with a metal in contact with the silicided fins to form a local interconnect connecting the fins.
