Abstract
Methods of forming integrated circuit devices include forming first and second electrically conductive lines at side-by-side locations on an integrated circuit substrate. Steps are performed to selectively etch each of the first and second electrically conductive lines into a respective pair of interconnects having facing ends that are separated from each other. This selective etching step is performed using a photolithography mask having a modified-rectangular mask pattern thereon, which is configured to define a shape of the facing ends of each of the pair of interconnects.
