摘要
The leveling of 200 nm trenches by an acid-copper electrolyte with polyethylene glycol (PEG), Cl-, bis(3-sulfopropyl) disulfide (SPS), and Janus Green B (JGB) was shown to be superior to leveling in electrolytes with combinations of only two or three of the additives. The leveling performance of an electrolyte with all four additives is dependent on both current density and JGB concentration. The leveling of the 200 nm features appears to be consistent with some, but not all, aspects of previous experiments on a 100 mu m scale. (C) 1999 The Electrochemical Society. S1099-0062(99)05-052-X.
