Abstract:
In a method of processing a substrate, a first plasma may be generated from a first reaction gas. A second plasma may be generated from a second reaction gas. The first plasma and the second plasma may be individually applied to the substrate. Thus, each of the at least two remote plasma sources may generate at least two plasmas under different process recipes, which may be optimized for processing the substrate. As a result, the substrate processed using the optimal plasmas may have a desired shape.
Abstract:
An etching method using plasma includes generating plasma by supplying process gases to at least one remote plasma source (RPS) and applying power to the at least one RPS, and etching an etching object by supplying water (H2O) and the plasma to a process chamber.
