Abstract:
A method of forming a self-forming spacer using oxidation. The self-forming spacer may include forming a fin field effect transistor on a substrate, the fin field effect transistor includes a gate on a fin, the gate is perpendicular to the fin; forming a gate spacer on the gate and a fin spacer on the fin, the gate spacer and the fin spacer are formed in a single step by oxidizing an exposed surface of the gate and an exposed surface of the fin; and removing the fin spacer from the fin.

Claim (Index 12):
A method comprising:\n forming fins in a top layer of a semiconductor-on-insulator (SOI) substrate such that an underlying buried oxide layer is exposed between each fin; patterning a polysilicon dummy gate above and perpendicular to the fins; simultaneously forming silicon dioxide gate spacers and a germanium oxide fin spacer by oxidizing exposed surfaces of the polysilicon dummy gate and exposed surfaces of the fins, wherein the gate spacers are formed only along vertical sidewalls of the polysilicon dummy gate, and wherein the germanium oxide fin spacer is formed both on vertical sidewalls and a top surface of the fins; removing the germanium oxide fin spacer without removing the silicon dioxide gate spacers by exposing both the silicon dioxide gate spacers and the germanium oxide fin spacer to a wet water etch; and replacing the polysilicon dummy gate with a metal gate.
