Abstract:
1. A semiconductor device comprising: a transistor comprising a plurality of replacement metal gates on a semiconductor substrate, wherein the transistor comprises first gates and at least one second gate, wherein the first gates have sources and drains and the at least one second gate is isolated from the first gates; gate spacers of a first insulating material around each first gate; a first insulating layer of a second insulating material between the gate spacers, wherein at least some of the second insulating material overlies sources and drains of the first gates; one or more insulating mandrels aligned over the first gates and the at least one second gate, wherein the insulating mandrels comprise the first insulating material; mandrel spacers around each insulating mandrel, wherein the mandrel spacers comprise the first insulating material; one or more first contacts to the sources and drains of the first gates through the first insulating layer between the mandrel spacers; a second contact to the at least one second gate through the first insulating material above the second gate; a third insulating layer over the transistor; and one or more local interconnects that contact the first contacts and the second contact through the third insulating layer.
