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 21):
An integrated circuit (IC) structure, comprising:\n a semiconductor substrate having IC devices formed thereon; an interconnection structure formed on the semiconductor substrate, wherein the interconnection structure includes a top metal feature within a first region coupled to the IC devices; 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 embedded in the passivation layer, landing on the top metal feature, and horizontally extending from the top metal feature in the first region to the opening in the second region, wherein the RDL metallic feature further includes a barrier layer disposed on the conductive feature, the barrier layer includes tantalum and nitrogen; a diffusion layer disposed on the barrier layer and being different from the barrier layer in composition, wherein the diffusion layer includes nitrogen, oxygen and tantalum; 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 the passivation layer includes a first silicon nitride film and an un-doped silica film on the first silicon nitride film, and a second silicon nitride film on the un-doped silica film, and wherein the RDL metallic feature includes a topmost surface below a bottom surface of the second silicon nitride film.
