  • Patent number: 11476254
    Abstract: Systems, methods and apparatus are provided for support pillars in vertical three-dimensional (3D) memory. An example method includes a method for forming arrays of vertically stacked memory cells, having horizontally oriented access devices and horizontally oriented storage nodes. The method includes depositing alternating layers of a dielectric material and a sacrificial material in repeating iterations to form a vertical stack. A plurality of spaced, first vertical openings are formed through the vertical stack adjacent areas where storage nodes will be formed. Support-pillar material is deposited in the plurality of spaced, first vertical openings to form structural support pillars. Second vertical openings are formed through the vertical stack adjacent the structural support pillars to define elongated vertical columns with first sidewalls of the alternating layers.

  • Publication number: 20220208771
    Abstract: A method used in forming an array of capacitors comprises forming an array of vertically-elongated first capacitor electrodes that project vertically relative to an outer surface. An insulative ring is formed circumferentially about individual vertically-projecting portions of the first capacitor electrodes. The insulative rings about immediately-adjacent of the first capacitor electrodes in a first straight-line direction are laterally directly against one another. The insulative rings about immediately-adjacent of the first capacitor electrodes in a second straight-line direction that is angled relative to the first straight-line direction are laterally-spaced from one another. A capacitor insulator is formed over sidewalls of the first capacitor electrodes. At least one second capacitor electrode is formed over the capacitor insulator. Additional methods, including structure independent of method, are disclosed.
