Beschreibung
Zusammenfassung:	The present invention provides a photoresist removal process and a method for manufacturing an interconnect using the same. One embodiment of the photoresist removal process includes, among other steps, providing a low dielectric constant (k) substrate having a photoresist layer located thereover, and removing the photoresist layer using a plasma which incorporates a gas which includes hydrogen or deuterium and a small amount of oxygen less than about 20 volume percent of the gas. Another embodiment of the photoresist removal process includes, among other steps, providing a low dielectric constant (k) substrate having a photoresist layer located thereover, removing a bulk portion of the photoresist layer using a plasma which incorporates a gas which includes hydrogen or deuterium, and removing a small portion of the photoresist layer using a plasma which incorporates a gas which includes oxygen, wherein the order of the two removing steps is interchangeable.
