    Abstract: In some embodiments, a method for forming an integrated circuit is provided. The method includes forming a first layer over a semiconductor wafer, the first layer having a first portion and a second portion. The first portion is patterned by projecting a first image field over the first portion of the first layer, where the first portion of the first layer corresponds to the first image field. The second portion is patterned by projecting a second image field over the second portion of the first layer, where the second portion of the first layer corresponds to the second image field. A second layer is formed over the first layer. The second layer is patterned by projecting a third image field over the second layer, where the third image field covers a majority of the first portion and a majority of the second portion of the first layer.

    Abstract: In some embodiments, the present disclosure relates to an integrated chip that includes a conductive structure arranged within a substrate or a first dielectric layer. A first barrier layer is arranged on outermost sidewalls and a bottom surface of the conductive structure. A second barrier layer is arranged on outer surfaces of the first barrier layer. The second barrier layer separates the first barrier layer from the substrate or the first dielectric layer. A second dielectric layer is arranged over the substrate or the first dielectric layer. A via structure extends through the second dielectric layer, is arranged directly over topmost surfaces of the first and second barrier layers, and is electrically coupled to the conductive structure through the first and second barrier layers.
