Abstract

An integrated circuit die includes a metal layer, a first passivation layer disposed above the metal layer, an aluminum containing redistribution layer disposed above the first passivation layer, an under bump metallization layer, and a redistribution layer plug. The redistribution layer plug is coupled to the metal layer and disposed in a via in the first passivation layer. The under bump metallization layer is coupled to the aluminum containing redistribution layer above the first passivation layer at a distance from the redistribution layer plug.
