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 15):
A semiconductor device comprising:\n a gate stack; a capping layer over the gate stack; a first sacrificial layer over the capping layer; a gate contact extending through the first sacrificial layer and in physical contact with the capping layer; a first spacer adjacent to and in physical contact with each of the gate stack, the capping layer, and the gate contact; a source/drain contact adjacent to the first spacer; a second sacrificial layer over the source/drain contact, the second sacrificial layer being different from the first sacrificial layer; a source/drain contact plug extending through the second sacrificial layer and in physical contact with the source/drain contact; and a helmet material over the first sacrificial layer and the first spacer.
