  • Patent number: 10770468
    Abstract: Embodiments of 3D memory structures and methods for forming the same are disclosed. A method for forming a three-dimensional (3D) memory structure includes forming a dielectric layer on a substrate and forming a first plurality of openings in the dielectric layer at a staircase region of the 3D memory structure. The method also includes forming a second plurality of openings in the dielectric layer at a peripheral device region of the 3D memory structure and forming at least one hard mask layer in the first plurality of openings of the staircase region and in the second plurality of openings of the peripheral device region. The method further includes etching the dielectric layer using the at least one hard mask layer to form first and second pluralities of via extension regions in top portions of the respective first and second pluralities of openings.
