    Abstract: The present disclosure relates to a multi-dimensional integrated chip having a redistribution layer vertically extending between integrated chip die, which is laterally offset from a back-side bond pad. The multi-dimensional integrated chip has a first integrated chip die with a first plurality of metal interconnect layers disposed within a first inter-level dielectric layer arranged onto a front-side of a first semiconductor substrate. The multi-dimensional integrated chip also has a second integrated chip die with a second plurality of metal interconnect layers disposed within a second inter-level dielectric layer abutting the first ILD layer. A bond pad is disposed within a recess extending through the second semiconductor substrate. A redistribution layer vertically extends between the first plurality of metal interconnect layers and the second plurality of metal interconnect layers at a position that is laterally offset from the bond pad.

    Abstract: Some embodiments of the present disclosure relate to a method of forming an integrated chip. The method includes forming a first interconnect wire within a first inter-level dielectric (ILD) layer over a substrate. One or more vias are formed on the first interconnect wire and within a second ILD layer separated from the substrate by the first ILD layer. One or more additional vias are formed within the second ILD layer. Respective ones of the one or more vias have a larger size than respective ones of the one or more additional vias. A thickness of the substrate is reduced, and the substrate is etched to form a bond pad opening extending through the substrate to the first interconnect wire. A bond pad is formed within the bond pad opening and directly over the one or more vias.
