Abstract

Electroplating methods enable the plating of photoresist defined features which have substantially uniform morphology. The electroplating methods include copper electroplating baths with reaction products of pyridyl alkylamines and bisepoxides to electroplate the photoresist defined features. Such features include pillars, bond pads and line space features.
