Abstract
The present disclosure, in some embodiments, relates to an integrated chip. The integrated chip includes a first interconnect and a second interconnect disposed within a first inter-level dielectric (ILD) layer over a substrate. A lower etch stop structure is disposed on the first ILD layer and a third interconnect is disposed within a second ILD layer that is over the first ILD layer. The third interconnect extends through the lower etch stop structure to contact the first interconnect. An interconnect patterning layer is disposed on the second interconnect and laterally adjacent to the lower etch stop structure.
