Abstract:
A semiconductor structure includes a substrate, and a replacement metal gate (RMG) structure is attached to the substrate. The RMG structure includes a lower portion and an upper tapered portion. A source junction is disposed on the substrate and attached to a first low-k spacer portion. A drain junction is disposed on the substrate and attached to a second low-k spacer portion. A first oxide layer is disposed on the source junction, and attached to the first low-k spacer portion. A second oxide layer is disposed on the drain junction, and attached to the second low-k spacer portion. A cap layer is disposed on a top surface layer of the RMG structure and attached to the first oxide layer and the second oxide layer.

Claim (Index 1):
A method comprising:\n forming a dummy gate stack on a substrate including a sacrificial spacer on the peripheral of the dummy gate stack; etching down the sacrificial spacer using an over etch process, wherein the over etch process comprises partially recessing the dummy gate stack, etching the sacrificial spacer down to the partially recessed dummy gate stack, and etching remaining portions of the sacrificial spacer to form gaps around and above a remaining portion of the dummy gate stack; forming a first low-k spacer portion and a second low-k spacer portion to fill the gaps around the remaining portions of the dummy gate stack and extending vertically along a sidewall of a dummy gate cavity; and forming a replacement metal gate (RMG) structure with the first low-k spacer portion and the second low-k spacer portion, wherein the RMG structure is robust for self-aligned contact formation.
