A substrate processing system includes a processing chamber including a substrate support to support a substrate. A coil includes at least one terminal. An RF source configured to supply RF power to the coil. A dielectric window is arranged on one surface of the processing chamber adjacent to the coil. A contamination reducer includes a first plate that is arranged between the at least one terminal of the coil and the dielectric window.

Metal contamination reduction in substrate processing systems with transformer coupled plasma

Methods of and apparatuses for laterally etching semiconductor substrates using an atomic layer etch process involving exposing an oxidized surface of a semiconductor substrate to a fluorine-containing etch gas and heating the substrate to remove non-volatile etch byproducts by a sublimation mechanism are provided herein. Methods also including additionally pulsing a hydrogen-containing gas when pulsing the fluorine-containing etch gas. Apparatuses also include an ammonia mixing manifold suitable for separately preparing and mixing ammonia for use in various tools.
