Abstract:
A method includes forming a passivation layer over a portion of a metal pad, forming a polymer layer over the passivation layer, and exposing the polymer layer using a photolithography mask. The photolithography mask has an opaque portion, a transparent portion, and a partial transparent portion. The exposed polymer layer is developed to form an opening, wherein the metal pad is exposed through the opening. A Post-Passivation Interconnect (PPI) is formed over the polymer layer, wherein the PPI includes a portion extending into the opening to connect to the metal pad.

Claim (Index 15):
An integrated circuit structure comprising:\n a substrate; a metal pad over the substrate; a first dielectric layer having a portion over the metal pad, wherein the first dielectric layer is formed of a first dielectric material; a second dielectric layer over the first dielectric layer, wherein the second dielectric layer is formed of a second dielectric material different from the first dielectric material, and the second dielectric material comprises:\n a first top surface; and \n a plurality of second top surfaces lower than the first top surface, wherein the plurality of second top surfaces are encircled, and separated from each other, by the first top surface; and \n a conductive line comprising:\n a via penetrating through the second dielectric layer to connect to the metal pad; and \n a pad electrically coupling to the via, wherein the pad has a bottom surface contacting the first top surface and the plurality of second top surfaces of the second dielectric material.
