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 10):
An integrated circuit (IC) structure, comprising:\n a semiconductor substrate having IC devices formed thereon; an interconnection structure formed on the semiconductor substrate and coupled to the IC devices, wherein the interconnection structure includes 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 and directly landing on the top metal feature of the plurality of conductive features, wherein the RDL metallic feature further includes a barrier layer disposed on the conductive feature; a diffusion layer disposed on the barrier layer, wherein the diffusion layer is a metallic oxide in an amorphous structure and is different from the barrier layer in composition; and a metallic layer disposed on the diffusion layer, wherein the RDL metallic feature is electrically connected to the top metal feature through the barrier layer and the diffusion layer, wherein each of the barrier layer, the diffusion layer and the metallic layer of the RDL metallic feature horizontally extends from the first region to the second region.
