.... To address these issues with copper, CMP slurries for copper are chemically complex. In addition to an oxidizer, a corrosion inhibitor is required to passivate the surface. The use of benzotriazole (BTA) as an inhibitor of copper corrosion was documented as early as 1947 ( Ref 4 ). It is clear that BTA bonds...
