Patent ID: 6899818

Claim:
A method of inhibiting adsorption of sodium-to integrated circuit surfaces during photoresist removal or post-metal etch cleanup with an organic solvent-containing composition, comprising contacting the surface with an organic solvent-containing composition comprising: a) 1,2-diaminocyclohexanetetracarboxylic acid (CYDTA), b) a nucleophilic amine present in an amount of from about 1 to less than about 50% by weight of the composition, c) a non-nitrogen containing weak acid in an amount sufficient to partially neutralize the nucleophilic amine such that the composition has an aqueous pH, when diluted with about 10 parts of water, of about 9.6 to about 10.9, said weak acid having a pKa value in aqueous solution of 2.0 or greater and an equivalent weight of less than 140, and the solvent is a stripping solvent system having a solubility parameter of from about 8 to about 15 and is present in an amount of from about 50% to about 85% by weight of the composition.
