Abstract: The present disclosure provides a polishing composition that includes at least one first amine, at least one second amine, and other components such as azoles. The first amine has a low molecular weight, for example 120 g/mol or less. The second amine has a high molecular weight, for example 125 g/mol or higher. The compositions can polish substrates that include copper and molybdenum, or alloys of each, at a high selectivity of copper to molybdenum.
