Abstract:
1. A method for treating a post-CMP processed substrate, the method comprising: providing the post-CMP processed substrate comprising a semiconductor material; and contacting the post-CMP processed substrate with a process solution consisting of a solvent selected from water, a non-aqueous solvent selected from the group consisting of a hydrocarbon, a halocarbon, an ether, a nitrile, an aromatic compound selected from the group consisting of benzotrifluoride, cyclohexanone, benzophenone, naphthalene, diphenyl sulfone, terphenyl, m-cresol, diphenyl ether, phenol, and combinations thereof, a lactate, a pyruvate, an alcohol, and combinations thereof, and combinations of water and the non-aqueous solvent and about 10 ppm to about 500,000 ppm of at least one surfactant having the formula (I) and (II): wherein R 1 and R 4 are each independently a straight or a branched alkyl group having from 3 to 10 carbon atoms; R 2 and R 3 are each independently a hydrogen atom or an alkyl group having from 1 to 5 carbon atoms; and m, n, p, and q are each independently a number that ranges from 0 to 20.
