Abstract:
A semiconductor device structure is provided. The semiconductor device structure includes a semiconductor substrate having a first surface, a second surface opposing the first surface, and sidewalls defining a recess that passes through the semiconductor substrate. A first interconnect layer is within a first dielectric structure disposed along the second surface, and a bonding pad is in the recess and extends to the first interconnect layer. A dielectric filling layer is also within the recess. The dielectric filling layer has an opening over a portion of the bonding pad and a curved upper surface over the bonding pad. A nickel layer is over the bonding pad and in the opening.

Claim (Index 18):
A method for forming a semiconductor device structure, comprising:\n forming a first interconnect layer within a first dielectric structure disposed along a surface of a semiconductor substrate; forming a recess in the semiconductor substrate, wherein the recess passes through the semiconductor substrate; forming an insulating layer lining interior sidewalls of the semiconductor substrate that define the recess; forming a nickel layer over the first interconnect layer and within the recess, wherein the nickel layer is laterally separated from the semiconductor substrate by the insulating layer and is electrically coupled to the first interconnect layer; and forming a gold layer over the nickel layer and within the recess, wherein the gold layer is recessed below a horizontal plane extending along a top of the insulating layer.
