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 13):
The method of  claim 12 , wherein there is a gap height between the second sacrificial material and the first sacrificial material.
