Zusammenfassung:Approaches for patterning metal line ends for back end of line (BEOL) interconnects, and the resulting structures, are described. In an example, a metallization layer of an interconnect structure for a semiconductor die includes a metal line disposed in a trench of an interlayer dielectric (ILD) material layer. The ILD material layer is composed of a first dielectric material. A conductive via is disposed in the ILD material layer, below and electrically connected to the metal line. A dielectric plug is directly adjacent to the metal line and the conductive via. The dielectric plug is composed of a second dielectric material different from the first dielectric material.
