  • Patent number: 11996151
    Abstract: A memory array comprising laterally-spaced memory blocks individually comprises a vertical stack comprising alternating insulative tiers and conductive tiers. Channel-material strings of memory cells extend through the insulative tiers and the conductive tiers. The laterally-spaced memory blocks in a lower one of the conductive tiers comprises elemental-form metal that extends longitudinally-along the laterally-spaced memory blocks proximate laterally-outer sides of the laterally-spaced memory blocks. A metal silicide or a metal-germanium compound is directly against laterally-inner sides of the elemental-form metal in the lower conductive tier and that extends longitudinally-along the laterally-spaced memory blocks in the lower conductive tier. The metal of the metal silicide or of the metal-germanium compound is the same as that of the elemental-form metal. Other embodiments, including method, are disclosed.

  • Publication number: 20240081057
    Abstract: An electronic device includes a source contact adjacent to a source stack, the source stack including one or more conductive materials, tiers of alternating conductive material and dielectric materials adjacent to the source contact, pillars extending vertically through the tiers and the source contact and at least partially into the source contact, a fill material extending vertically through the tiers to the source contact, and a metal silicide material between the fill material and an upper surface of the source contact. Related devices, systems, and methods are also disclosed.

  • Patent number: 5551416
    Abstract: A nebulizer for use in administering a medicament to a patient undergoing treatment for example, comprises an ultrasonic piezo-electric transducer (60) and a transducer drive system (D) which is caused to drive said transducer at or near its anti-resonant frequency. There is also provided means to optimize nebulized fluid particle size and transfer to the patients lungs for example, by operating at an anti-resonant frequency in the range of 1.36 to 1.56 MHz and having a single outlet baffle and relatively short outlet tube (24) arrangement.
