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 5):
The method of  claim 2 , further comprising:\n forming a second ILD layer which comprises a gate via contact opening that exposes a portion of the gate contact capping layer, and a portion of the source/drain contact capping layer formed on the vertical source/drain contact; etching the exposed portion of the gate contact capping layer selective to the exposed portion of the source/drain contact capping layer to expose a portion of the vertical gate contact; and forming a gate via contact in the gate via contact opening of the second ILD layer in contact with the exposed portion of the vertical gate contact and the exposed portion of the source/drain contact capping layer; wherein a portion of the gate via contact overlaps a portion of the vertical source/drain contact; and wherein the source/drain contact capping layer electrically insulates the overlapping portions of the gate via contact and the vertical source/drain contact.
