  • Patent number: 11942364
    Abstract: In some embodiments, the present disclosure relates to a method of forming an interconnect. The method includes forming an etch stop layer (ESL) over a lower conductive structure and forming one or more dielectric layers over the ESL. A first patterning process is performed on the one or more dielectric layers to form interconnect opening and a second patterning process is performed on the one or more dielectric layers to increase a depth of the interconnect opening and expose an upper surface of the ESL. A protective layer is selectively formed on sidewalls of the one or more dielectric layers forming the interconnect opening. A third patterning process is performed to remove portions of the ESL that are uncovered by the one or more dielectric layers and the protective layer and to expose the lower conductive structure. A conductive material is formed within the interconnect opening.
