Abstract

An integrated circuit (IC) device includes a first passivation layer over a substrate. The IC device further includes a redistribution line over the first passivation layer, wherein the redistribution line has a barrel-shaped profile. The IC device further includes a second passivation layer over the redistribution line. The IC device further includes a polymer layer over the second passivation layer.
