  • Patent number: 12302623
    Abstract: Some embodiments include ferroelectric assemblies. Some embodiments include a capacitor which has ferroelectric insulative material between a first electrode and a second electrode. The capacitor also has a metal oxide between the second electrode and the ferroelectric insulative material. The metal oxide has a thickness of less than or equal to about 30 ?. Some embodiments include a method of forming an assembly. A first capacitor electrode is formed over a semiconductor-containing base. Ferroelectric insulative material is formed over the first electrode. A metal-containing material is formed over the ferroelectric insulative material. The metal-containing material is oxidized to form a metal oxide from the metal-containing material. A second electrode is formed over the metal oxide.

  • Publication number: 20240315001
    Abstract: Memory circuitry comprises vertically-alternating tiers of insulative material and memory cells. The memory cells individually comprising a transistor comprise a first source/drain region, a second source/drain region, and a channel region between the first and second source/drain regions. A gate is operatively-proximate the channel region. A capacitor comprises a first capacitor electrode, a second capacitor electrode, and a capacitor insulator between the first and second capacitor electrodes. The first capacitor electrode is directly electrically coupled to the first source/drain region. The second capacitor electrode of multiple of the capacitors is directly electrically coupled with one another. Digitlines extend elevationally through the vertically-alternating tiers. Individual of the second source/drain regions of individual of the transistors that are in different memory-cell tiers are directly electrically coupled to individual of the digitlines.

  • Publication number: 20240164114
    Abstract: A method of forming a vertical transistor comprising a top source/drain region, a bottom source/drain region, a channel region vertically between the top and bottom source/drain regions, and a gate operatively laterally-adjacent the channel region comprises, in multiple time-spaced microwave annealing steps, microwave annealing at least the channel region. The multiple time-spaced microwave annealing steps reduce average concentration of elemental-form H in the channel region from what it was before start of the multiple time-spaced microwave annealing steps. The reduced average concentration of elemental-form H is 0.005 to less than 1 atomic percent. Structure embodiments are disclosed.
