Abstract:
Use of a chemical mechanical polishing (CMP) composition (Q) for chemical mechanical polishing of a substrate (S) comprising (i) cobalt and/or (ii) a cobalt alloy and (iii) Ti N and/or TaN, wherein the CMP composition (Q) comprises (E) Inorganic particles (F) at least one organic compound comprising an amino-group and an acid group (Y), wherein said compound comprises n amino groups and at least n+1 acidic protons, wherein n is a integer≥1. (G) at least one oxidizer in an amount of from 0.2 to 2.5 wt.-% based on the total weight of the respective CMP composition, (H) an aqueous medium wherein the CMP composition (Q) has a pH of more than 6 and less than 9.

Claim (Index 13):
A chemical mechanical polishing (CMP) composition, comprising:\n (A) colloidal silica particles in a total amount of from 0.01 wt.-% to 2 wt.-% based on a total weight of the CMP composition; (B) at least one organic compound (B) selected from the group consisting of glutamic acid, aspartic acid, ethylenediaminetetraacetic acid, diethylene triamine pentaacetic acid, cysteic acid, aminotris(methylenephosphonic acid), diethylenetriamine penta(methylene phosphonic acid) and ethylenediamine tetra(methylene phosphonic acid) in a total amount of from 0.1 wt-% to 2 wt.-% based on the total weight of the CMP composition; (C) hydrogen peroxide in a total amount of from 0.2 wt.-% to 1.8 wt.-% based on the total weight of the CMP composition; (D) an aqueous medium; (E) at least one corrosion inhibitor (E) selected from the group consisting of imidazole, benzimidazole, 4-(dimethylamino) benzoic acid, terephthalic acid Isophthalic acid, 6,6\u2032,6\u2033-(1,3,5-Triazine-2,4,6-triyltriimino)trihexanoic acid, phenyltetrazole, N-Lauroylsarcosine, 4-Dodecylbenzene sulfonic acid and phosphoric acid C6-C10 alkyl ester in a total amount of from 0.002 wt.-% to 0.1 wt.-% based on the total weight of the CMP composition; and (F) at least one amphiphilic non-ionic surfactant comprising a polyoxyalkylene group (F) in a total amount of from 0.001 to 0.05 wt.-% based on the total weight of the CMP composition, wherein the CMP composition has a pH of more than 6 and less than 9.
