Abstract
Embodiments of the present invention generally relate to methods for forming a metal structure and passivation layers. In one embodiment, metal columns are formed on a substrate. The metal columns are doped with manganese, aluminum, zirconium, or hafnium. A dielectric material is deposited over and between the metal columns and then cured to form a passivation layer on vertical surfaces of the metal columns.
