Abstract:
Semiconductor devices and methods are provided to fabricate FET devices having overlapping gate and source/drain contacts while preventing electrical shorts between the overlapping gate and source/drain contacts. For example, a semiconductor device includes a FET device, a vertical source/drain contact, a source/drain contact capping layer, and a vertical gate contact. The FET device includes a source/drain layer, and a gate structure. The vertical source/drain contact is formed in contact with a source/drain layer of the FET device. The source/drain contact capping layer is formed on an upper surface of the vertical source/drain contact. The vertical gate contact is formed in contact with a gate electrode layer of the gate structure. A portion of the vertical gate contact overlaps a portion of the vertical source/drain contact, wherein the source/drain contact capping layer electrically insulates the overlapping portions of the vertical gate and source/drain contacts.

Claim (Index 2):
The method of  claim 1 , further comprising:\n forming a gate contact capping layer on an upper surface of the vertical gate contact prior to forming the vertical source/drain contact; and forming a source/drain contact capping layer on an upper surface of the vertical source/drain contact; wherein the source/drain contact capping layer is formed of an insulating material that has etch selectivity with respect to insulating materials that form the insulating spacer and the gate contact capping layer.
