  • Patent number: 10263007
    Abstract: An array of elevationally-extending strings of memory cells, where the memory cells individually comprise a programmable charge storage transistor, comprises a substrate comprising a first region containing memory cells and a second region not containing memory cells laterally of the first region. The first region comprises vertically-alternating tiers of insulative material and control gate material. The second region comprises vertically-alternating tiers of different composition insulating materials laterally of the first region. A channel pillar comprising semiconductive channel material extends elevationally through multiple of the vertically-alternating tiers within the first region. Tunnel insulator, programmable charge storage material, and control gate blocking insulator are between the channel pillar and the control gate material of individual of the tiers of the control gate material within the first region.

  • Publication number: 20190081061
    Abstract: A device comprises an array of elevationally-extending transistors and a circuit structure adjacent and electrically coupled to the elevationally-extending transistors of the array. The circuit structure comprises a stair step structure comprising vertically-alternating tiers comprising conductive steps that are at least partially elevationally separated from one another by insulative material. Operative conductive vias individually extend elevationally through one of the conductive steps at least to a bottom of the vertically-alternating tiers and individually electrically couple to an electronic component below the vertically-alternating tiers. Dummy structures individually extend elevationally through one of the conductive steps at least to the bottom of the vertically-alternating tiers. Methods are also disclosed.

  • Publication number: 20190067412
    Abstract: Some embodiments include apparatuses and methods of forming the apparatuses. One of the apparatuses includes conductive materials located in different levels of the apparatus, dielectric materials located in different levels of the apparatus, a first conductive contact, and a second conductive contact. One of the conductive materials is between two of the dielectric materials. One of the dielectric materials is between two of the conductive materials. The first conductive contact has a length extending through the conductive materials and the dielectric materials in a direction perpendicular to the levels of the apparatus. The first conductive contact is electrically separated from the conductive materials. The second conductive contact contacts a group of conductive materials of the conductive materials.

  • Publication number: 20180254283
    Abstract: Some embodiments include an integrated structure having a semiconductor base and an insulative frame over the semiconductor base. The insulative frame has vertically-spaced sheets of first insulative material, and pillars of second insulative material between the vertically-spaced sheets. The first and second insulative materials are different from one another. Conductive plates are between the vertically-spaced sheets and are directly against the insulative pillars. Some embodiments include capacitors, and some embodiments include methods of forming capacitors.

  • Publication number: 20180151415
    Abstract: Array contacts for semiconductor memories may be formed using a first set of parallel stripe masks and subsequently a second set of parallel stripe masks transverse to the first set. For example, one set of masks may be utilized to etch a dielectric layer, to form parallel spaced trenches. Then the trenches may be filled with a sacrificial material. That sacrificial material may then be masked transversely to its length and etched, for example. The resulting openings may be filled with a metal to form array contacts.
