Abstract:
A method for producing a finFET to prevent gate contact and trench silicide (TS) electrical shorts. Embodiments include forming a finFET over a substrate, the finFET comprising an epi S/D region formed at sides of a gate; forming an α-Si layer in a recess over the epi S/D; forming an oxide layer over the α-Si layer; forming a non-TS isolation opening over the substrate; forming a low dielectric constant layer in the non-TS isolation opening; removing the oxide layer and α-Si layer; forming an opening over the gate and an opening over the epi S/D region; and forming a gate contact in the opening over the gate and an epi S/D contact over the opening over the epi S/D region.

Claim (Index 15):
A method comprising:\n forming fin field effect transistor (finFET) over a substrate, the finFET comprising a gate, sidewall spacer, and epitaxial source/drain (epi S/D) region; forming a first dielectric over the epi S/D region, the first dielectric comprising a bottom photoresist layer and a top dielectric cap; removing a first portion of the first dielectric from a non-trench silicide (non-TS) isolation region; removing the sidewall spacer from the gate to form an opening between the gate and the epi S/D region; filling the opening between the gate and the epi S/D region with a second dielectric; removing a second portion of the first dielectric to expose the bottom photoresist layer over the epi S/D region; removing the bottom photoresist layer to expose the epi S/D region; removing a gate cap to expose the gate; and forming epi S/D contact and gate contact.
