摘要: | Effects of a new combination of additives in acid electroplating solution on the properties of Cu thin films have been investigated, The electroplated Cu films exhibit an excellent superfilling behavior. 0.18 mu m vias with an aspect ratio exceeding 5 were filled completely without any void or seam. Strong (111) texture was found for the electroplated Cu films. The resistivity of a 450-nm-thick Cu film was measured to be 1.84 mu Omega cm. (C) 2000 American Vacuum Society.
