Abstract:
Systems and methods discussed herein are directed towards processing of substrates, including forming a plurality of features in a target layer on a substrate. The formation of the plurality of features includes a main etch operation that forms the plurality of features to a first depth in the target layer. The main etch operation is followed by a phase shift sync pulsing (PSSP) operation, and these two operations are repeated iteratively to form the features to a predetermined depth. The PSSP operation includes one or more cycles of RF source power and RF bias power, this cycle deposits a protective coating in and on the features and then etches a portion of the protective coating to expose portions of the feature.

Claim (Index 1):
A method for processing a substrate, comprising:\n (a) etching a substrate in the presence of an etching gas composition to form a feature in a top surface of the substrate, the feature having a first depth in a target layer disposed on the substrate; (b) depositing, subsequent to (a), a protective coating on a sidewall of the feature, wherein depositing the protective coating comprises:\n (1) applying a pulsed RF source power for a first predetermined period of time, and forming, in response to applying the pulsed RF source power, a first layer on the top surface of the substrate, on the sidewall of the feature, and on a bottom of the feature; \n (2) applying a pulsed RF bias power to the substrate for a second predetermined period of time and removing, in response to applying the pulsed RF bias power, a portion of the first layer; and \n (3) repeating (b)(1) and (b)(2) to form the protective coating; and \n (c) repeating (a) and (b) until the feature extends to a predetermined depth in the target layer.
