Abstract:
The present disclosure provides an integrated circuit (IC) structure. The IC structure includes a semiconductor substrate; an interconnection structure formed on the semiconductor substrate; and a redistribution layer (RDL) metallic feature formed on the interconnection structure. The RDL metallic feature further includes a barrier layer disposed on the interconnection structure; a diffusion layer disposed on the barrier layer, wherein the diffusion layer includes metal and oxygen; and a metallic layer disposed on the diffusion layer.

Claim (Index 1):
An integrated circuit (IC) structure, comprising:\n a semiconductor substrate; an interconnection structure formed on the semiconductor substrate and including a top metal feature within a first region; a passivation layer disposed on the interconnection structure and having an opening within a second region being distanced away from the first region; and a redistribution layer (RDL) metallic feature formed in the passivation layer, wherein the RDL metallic feature is landing on the top metal feature, and horizontally extends from the top metal feature in the first region to the opening in the second region, and wherein the RDL metallic feature further includes a barrier layer disposed on the top metal feature, wherein the barrier layer includes a metal and nitrogen; a diffusion layer disposed on the barrier layer, wherein the diffusion layer includes the metal and oxygen; and a metallic layer disposed on the diffusion layer.
