Electroplating methods using an electroplating bath containing metal ions and a suppressor additive, an accelerator additive, and a leveler additive, together with controlling the current density applied to a substrate, avoid defects in plated films on substrates having features with a range of aspect ratios, while providing good filling and thickness distribution. The methods include, in succession, applying DC cathodic current densities optimized to form a conformal thin film on a seed layer, to provide bottom-up filling, preferentially on features having the largest aspect ratios, and to provide conformal plating of all features and adjacent field regions. Including a leveling agent in the electroplating bath produces films with better quality after subsequent processing.
