Patent ID: 7393819

Claim:
A cleaning composition having the property of being capable of cleaning residues from microelectronic substrates having on the substrate (1) a dielectric that is a porous dielectric, a low-κ dielectric or a high-κ dielectric, and (2) copper metallization, said cleaning composition is a silicate free composition and consists of: from about 0.05% to 30% by weight of one or more non-ammonia producing strong base containing non-nucleophilic, positively charged counter ions; from about 5 to about 99.95% by weight of dimethyl piperidone; from about 0 to about 95% by weight water or other organic co-solvent; from about 0 to 40% by weight of an other metal corrosion inhibitor compounds; from 0 to 5% by weight of a surfactant; from about 0 to about 5% by weight of a metal chelating agent selected from the group consisting of trans-1,2-cyclohexanediamine tetraacetic acid and ethylenediamine tetra(methylene phosphonic acid); and from about 0 to 10% by weight of a fluoride compound; wherein the water or other organic co-solvent consists of water or at least one other organic co-solvent selected from the group consisting of dimethyl sulfoxide, sulfolane, diethanolamine, triethanolamine, 2-(methylamino)ethanol and 3-(diethylamino)-1,2-propanediol.
