摘要
A method of generating hollow cathode plasma and a method of treating a large area substrate using the hollow cathode plasma are disclosed. In the methods, the hollow cathode plasma is generated by a gas introduced between a hollow cathode in which a plurality of lower grooves where plasma is generated is defined in a bottom surface thereof and a baffle in which a plurality of injection holes is defined. A substrate disposed on a substrate support member is treated using the hollow cathode plasma passing through the injection holes. The uniform plasma having high density can be generated by hollow cathode effect due to the hollow cathode having the lower grooves and the injection holes of the baffle. Also, since the substrate can be treated using a hydrogen gas and a nitrogen gas in an ashing process, a damage of a low dielectric constant dielectric can be minimized.
