Abstract:
Embodiments disclosed herein relate generally to forming a gate layer in high aspect ratio trenches using a cyclic deposition-etch process. In an embodiment, a method for semiconductor processing is provided. The method includes performing a cyclic deposition-etch process to form a conformal film over a bottom surface and along sidewall surfaces of a feature on a substrate. The method includes forming a dielectric cap layer on the conformal film. The method includes performing an anneal process on the conformal film.

Claim (Index 13):
A method for semiconductor processing, the method comprising:\n forming fins on a substrate, sidewalls of the fins and a bottom surface between the sidewalls of the fins defining a trench therebetween; forming a dummy gate layer in the trench and over the fins, forming the dummy gate layer comprising:\n depositing at least a portion of the dummy gate layer in the trench by performing a cyclic deposition-etch process, the at least the portion of the dummy gate layer merging by lateral growth from the sidewalls of the fins; \n forming a dielectric cap layer on the portion of the dummy gate layer; and \n annealing the portion of the dummy gate layer; \n after forming the dummy gate layer, patterning the dummy gate layer to form a dummy gate structure over the fins: and after patterning the dummy gate layer, replacing the dummy gate structure with a gate structure.
