  • Publication number: 20250365920
    Abstract: Methods and apparatus are provided for multi-sided storage nodes in three-dimensional memory. An array of vertically stacked memory cells can include horizontally oriented access devices having gates formed horizontally at a different level from each other, channel regions, and first source/drain regions and second source/drain regions separated by the channel regions. The storage nodes include a first electrode, extending in a horizontal direction from, and in electrical contact with, an electrical interface to the second source/drain region of a given one of the vertically stacked memory cells, the first electrode having interior and exterior surfaces, a dielectric material, and a second electrode separated from the interior and exterior surfaces of the first electrode by the dielectric material.

  • Publication number: 20240431095
    Abstract: Methods, apparatuses, and systems related to a three-dimensional semiconductor device having a doped liner at least disposed between a capacitor and an access device. The doped liner may be configured to provide dopants that diffuse into a semiconductor path of the access device and improve an electrical connection between the access device and the capacitor.

  • Publication number: 20240389302
    Abstract: Methods, systems, and devices for contact foot wet pullback with liner wet punch are described. A first etching operation may be performed on a stack of materials and a first insulative material to form a plurality of segments including contacts, the contacts formed from a first conductive material of the stack of materials and extending at least partially through the first insulative material. A first liner material may be deposited over the segments and the first insulative material, and a directional gas bias operation may be performed to transform a portion of the first liner material in contact with an extension of the contacts into a second liner material. A second etching operation may be performed to remove the second liner material and expose a surface of the extension, and a third etching operation may be performed remove at least a portion of the extension.

  • Patent number: 11563008
    Abstract: Some embodiments include an integrated assembly having digit-line-contact-regions between pairs of capacitor-contact-regions. The capacitor-contact-regions are arranged with six adjacent capacitor-contact-regions in a substantially rectangular configuration. Conductive plugs are coupled with the capacitor-contact-regions. Conductive redistribution material is coupled with the conductive plugs. Upper surfaces of the conductive redistribution material are arranged in a substantially hexagonal-close-packed configuration. Digit lines are over the digit-line-contact-regions. Insulative regions are between the digit lines and the conductive plugs. The insulative regions contain voids and/or low-k dielectric material. Capacitors are coupled with the upper surfaces of the conductive redistribution material.

  • Patent number: 10661273
    Abstract: Methods of forming two-dimensional nanopatterns are provided. The method may comprise periodically contacting a vibrating tool comprising a patterned grating edge with a substrate along a first direction in a grating-vibrational indentation patterning process. The patterned grating edge defines a plurality of rows and a plurality of interspersed troughs. The periodic contacting creates a two dimensional array of discontinuous voids in a single-stroke across the surface of the substrate. In other aspects, a microfluidic device for selective arrangement of a microspecies or nanospecies is provided, that includes a substrate comprising a surface defining a two-dimensional pattern of microvoids or nanovoids. In yet other aspects, the present disclosure provides a method for selective arrangement of a microspecies or nanospecies on a substrate.
