Abstract
A semiconductor device includes a conductive pattern formed over a semiconductor substrate, and an interconnect structure formed over the conductive pattern. The semiconductor device also includes a first passivation layer over the conductive pattern; a second passivation layer over the first passivation layer; an interconnect structure disposed over the conductive pattern and in the first passivation layer and the second passivation layer; and an interconnect liner disposed between the interconnect structure and the conductive pattern and surrounding the interconnect structure, wherein inner sidewall surfaces of the interconnect liner are in direct contact with the interconnect structure, and a maximum distance between outer sidewall surfaces of the interconnect liner is greater than a width of the conductive pattern.
