An electroplated cobalt deposit and a method of electrodepositing cobalt on a surface to produce a level deposit across the surface of the substrate. The cobalt electrolyte contains (1) a source of cobalt ions; (2) boric acid; (3) a pH adjuster; and (4) an organic additive, which contains a suppressor. The electroplated cobalt deposit exhibits a level surface such that the thickness difference across substantially the entire surface of the substrate of less than about 200 nm.
