Abstract:
In some embodiments, the present disclosure relates to an integrated chip. The integrated chip includes a plurality of interconnect layers within an inter-level dielectric (ILD) structure disposed along a front-side of a substrate. A dielectric layer is arranged along a back-side of the substrate and a conductive bond pad is separated from the substrate by the dielectric layer. A back-side through-substrate-via (BTSV) extends through the substrate and the dielectric layer. A conductive bump is arranged over the conductive bond pad. The conductive bond pad has a substantially planar lower surface extending from over the BTSV to below the conductive bump. A BTSV liner separates sidewalls of the BTSV from the substrate. The sidewalls of the BTSV directly contact sides of both the BTSV liner and the dielectric layer.
