摘要
A system and method for adding a source contact, a drain contact, and an apparent gate contact to a FinFET having a fin including a source region, a drain region, and a gate disposed over the fin forming one or more transistor junctions with the fin. The method comprises producing a source contact opening extending downward to a first region electrically coupled to the source region, a drain contact opening extending downward to a second region electrically coupled to the drain region, and a gate contact opening extending downward to a third region electrically isolated from the gate, and filling the source contact opening, the drain contact opening, and the gate contact opening with a conductive metal.
