Nitric acid was the first adopted oxidizer for copper CMP. It was selected for two reasons; the nitrate ions formed by the dissociation of the strong acid assist in forming Cu(II) ions, rather than Cu(I) ions, while the presence of H + ions encourages the dissolution of copper, as indicated by the Pourbaix diagram in Figure 7.26 [3].The findings of subsequent potentiodynamic studies, such as .

Ostwald process - Wikipedia

Ostwald process - Wikipedia

Description Stage 1. Ammonia is converted to nitric acid in 2 stages. It is oxidized by heating with oxygen in the presence of a catalyst such as platinum with 10% rhodium, platinum metal on fused silica wool, copper or nickel, to form nitric oxide (nitrogen(II) oxide) and water (as steam). This reaction is strongly exothermic, making it a useful heat source once initiated:
