Abstract:
Disclosed are methods and integrated circuit (IC) structures. The methods enable formation of a gate contact on a gate above (or close thereto) an active region of a field effect transistor (FET) and provide protection against shorts between the gate contact and metal plugs on source/drain regions and between the gate and source/drain contacts to the metal plugs. A gate with a dielectric cap and dielectric sidewall spacer is formed on a FET channel region. Metal plugs with additional dielectric caps are formed on the FET source/drain regions such that the dielectric sidewall spacer is between the gate and the metal plugs and between the dielectric cap and the additional dielectric caps. The dielectric cap, dielectric sidewall spacer and additional dielectric caps are different materials preselected to be selectively etchable, allowing for misalignment of a contact opening to the gate without risking exposure of any metal plugs and vice versa.

Claim (Index 20):
The integrated circuit structure of  claim 15 , further comprising a dielectric layer above the source/drain regions, the dielectric layer having plug openings containing the metal plugs and further having a divot that is adjacent to a metal plug sidewall and that is filled with the conductive material.
