Abstract
Embodiments of the present disclosure generally relate an interconnect structure formed on a substrate and a method of forming the interconnect structure thereon. In one embodiment, a method of forming an interconnect structure includes forming an opening comprising a via and a trench in an insulating structure formed on a substrate, forming a first passivation layer in the opening, removing a portion of the first passivation layer from the opening, and selectively depositing a first metal containing material in the via.
