Chemistry for removal of photo resist, organic sacrificial fill material and etch polymer

摘要

Methods and associated structures of forming a microelectronic device are described. Those methods may include utilizing a cleaning mixture comprising a solvent such as ethylene glycol monopropyl ether, an inorganic base, an organic base, a copper corrosion inhibitor and a surfactant to clean at least one of a polymer residue, a organic sacrificial fill material and etched or un-etched photo resist from a Damascene structure of a microelectronic structure comprising a porous oxide dielectric.
