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.
