Abstract
An apparatus and method for plasma enhanced monolayer (PEM) processing, wherein excited species from a non-condensable gas plasma are delivered to a substrate surface during the reaction of a chemical precursor with a previously chemisorbed monolayer on the substrate surface; the excited species lower the activation energy of the monolayer formation reaction and also modulate the film properties. In preferred embodiments a process reactor has linear injectors arranged diametrically above a substrate and reactive gases are sequentially injected onto the substrate surface while it is being rotated. The reactor can be operated in pulse precursor and pulsed plasma, constant precursor and constant plasma modes, or a combination thereof.
