Abstract: A process for forming layered structures using plasma enhanced atomic layer deposition (PEALD) to deposit a TS-SiN film on trenches (or space and line patterns) of a substate. The SiN deposition process is adapted to form a TS-SiN film by controlling the argon to nitrogen flow ratio during deposition cycles such as by tuning the ratio of a first gas to a second gas provided continuously during PEALD deposition. The SiN film has etching selectivity between horizontal and vertical portions of the film and also etching selectivity between films at top and bottom portions of the patterns or trenches, e.g., with a portion of the thin film at the bottom of the pattern or trench having a higher WER than the thin film at the top of the pattern or trench. Wet etching may then be used to selectively etch material from the thin film in a topologically selective manner.
