    Abstract: An apparatus and method for processing a substrate using plasma, which has high plasma stability and process reproducibility, is provided. The method includes providing an apparatus for processing a substrate comprising a plasma generating region and a process region separate from the plasma generating region, placing the substrate including a silicon layer and an oxide layer in the process region, forming a hydrogen atmosphere in the process region by providing a hydrogen-based gas to the process region without passing through the plasma generating region, generating plasma by providing a fluorine-based gas to the plasma generating region, and providing the generated plasma to the process region to selectively remove the silicon layer compared to the oxide layer.

    Abstract: A substrate processing apparatus using plasma capable of efficiently controlling the selectivity ratio of a silicon layer and an oxide layer is provided. The substrate processing apparatus comprises a first space disposed between an electrode and an ion blocker; a second space disposed between the ion blocker and a shower head; a processing space under the shower head for processing a substrate; a first supply hole for providing a first gas for generating plasma to the first space; a second supply hole for providing a second gas to be mixed with an effluent of the plasma to the second space; and a first coating layer formed on a first surface of the shower head facing the second space, not formed on a second surface of the shower head facing the processing space, and containing nickel.
