Abstract
An integrated circuit (IC) device includes a redistribution line over a substrate, wherein an entire sidewall of the redistribution line is curved. The IC device further includes a passivation layer over the redistribution line, wherein a distance from a bottommost surface of the passivation layer to the substrate is less than a distance from a bottommost surface of the redistribution line to the substrate. The IC device further includes a polymer layer over the passivation layer.
