    摘要: A method of forming a feature in a low-k dielectric layer is provided. A low-k dielectric layer is placed over a substrate. A patterned photoresist mask is placed over the low-k dielectric layer. At least one feature is etched into the low-k dielectric layer. A CO conditioning is preformed on the at least one feature after the at least one feature is etched. The patterned photoresist mask is stripped after the CO conditioning.
