Abstract:
A semiconductor device such as a fin field effect transistor and its method of manufacture are provided. In some embodiments gate spacers are formed over a semiconductor fin, and a first gate stack is formed over the fin. A first sacrificial material with a large selectivity to the gate spacers is formed over the gate stack, and a second sacrificial material with a large selectivity is formed over a source/drain contact plug. Etching processes are utilized to form openings through the first sacrificial material and through the second sacrificial material, and the openings are filled with a conductive material.

Claim (Index 1):
A method of manufacturing a semiconductor device, the method comprising:\n forming gate spacers over a semiconductor fin; forming a first gate stack adjacent to the gate spacers; forming a second gate stack over the semiconductor fin; forming a first sacrificial material over the first gate stack and the second gate stack, wherein the first sacrificial material has a dry etch selectivity to the gate spacers of greater than about 12; placing a first conductive material and a second sacrificial material into a region between the first gate stack and the second gate stack and between the first sacrificial material over the first gate stack and the first sacrificial material over the second gate stack, wherein the second sacrificial material is different from the first sacrificial material and has an etch selectivity to the gate spacers of greater than about 12; etching a first opening through the first sacrificial material; and etching a second opening through the second sacrificial material.
