ADDITIVES FOR ELECTRODEPOSITION

摘要

Leveling additives, their use in electrodeposition, and regeneration are described. In one embodiment, an electrodeposition bath may include a non-aqueous liquid and an optionally substituted aromatic hydrocarbon. The optionally substituted aromatic hydrocarbon may be protonated. A method prepares an electrodeposition bath with a leveling additive may include: adding an optionally substituted basic aromatic hydrocarbon to a non-aqueous liquid; and protonating the basic aromatic hydrocarbon in the non-aqueous liquid.
