    摘要: Described are methods of and compositions for electrodepositing copper or other metals onto interconnects of a semiconductor substrate from an electroplating composition containing at least one nitrogen-containing additive. The nitrogen-containing additive has a molecular weight of between 10 and 1000, a concentration of between 5.0 and 10.0 milligrams per liter of the electroplating composition. The methods and compositions result in electroplated copper interconnects that have smooth surfaces that are relatively free of pits and humps.
