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 1):
An integrated circuit structure comprising:\n a substrate; a metal pad over the substrate; a passivation layer comprising a portion over the metal pad; a polymer layer over the passivation layer, wherein the polymer layer comprises a plurality of recesses extending from a top surface of the polymer layer into an intermediate level of the polymer layer, wherein the intermediate level is between the top surface and a bottom surface of the polymer layer; a Post-Passivation Interconnect (PPI) comprising:\n a PPI via penetrating through the polymer layer to connect to the metal pad; and \n a PPI pad electrically coupling to the PPI via, wherein the PPI pad comprises a first portion extending into the plurality of recesses of the polymer layer; \n a metal finish on the PPI pad; and a solder region overlying and contacting the metal finish, wherein the solder region is spaced apart from the PPI via.
