    Abstract: An apparatus including an array of at least two vertically stacked layers of integrated circuit device components separated by a dielectric layer on a substrate, wherein each of the at least two vertically stacked layers includes a laterally disposed contact point; and an electrically conductive interconnection coupled to a lateral edge of the contact point of each of the at least two vertically stacked layers and bridging the dielectric layer. A method including forming an array of at least two vertically stacked layers of integrated circuit device components separated by a dielectric layer on a substrate, forming a trench that exposes a lateral contact point of each of the at least two vertically stacked layers; depositing a polymer in the trench, wherein the polymer preferentially aligns to a material of the lateral contact point and bridges the dielectric layer; and modifying or replacing the polymer with an electrically conductive material.
