A method for performing gapfill of features of a substrate including a) arranging a substrate on a substrate support in a processing chamber; b) performing atomic layer deposition (ALD) to deposit film in a feature of the substrate; c) supplying an inhibitor plasma gas to the processing chamber and striking plasma in the processing chamber to inhibit deposition in upper portions of the feature as compared to lower portions of the feature; d) repeating b) N times, where N is an integer greater than one, and repeating c) M of the N times where M is an integer greater than zero and less than or equal to N; e) supplying an etch gas to the processing chamber to etch the film in the feature of the substrate; and f) repeating b) to e) one or more times to gapfill the feature of the substrate.
