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 pre
A method for etching a feature in a low-k dielectric layer through a photoresist etch mask over a substrate. A gas-modulated cyclic stripping process is performed for more than three cycles for stripping a single photoresist mask. Each cycle of the gas-modulated cyclic stripping proc
