  • Patent number: 10672785
    Abstract: Some embodiments include a method of forming vertically-stacked memory cells. An opening is formed through a stack of alternating insulative and conductive levels. Cavities are formed to extend into the conductive levels. Regions of the insulative levels remain as ledges which separate adjacent cavities from one another. Material is removed from the ledges to thin the ledges, and then charge-blocking dielectric and charge-storage structures are formed within the cavities. Some embodiments include an integrated structure having a stack of alternating insulative levels and conductive levels. Cavities extend into the conductive levels. Ledges of the insulative levels separate adjacent cavities from one another. The ledges are thinned relative to regions of the insulative levels not encompassed by the ledges.

  • Patent number: 10658461
    Abstract: Methods for forming field effect transistors include forming a stack of nanowires of alternating layers of channel material and sacrificial material, with a top layer of the sacrificial material forming a top layer of the stack. A dummy gate is formed over the stack. Channel material and sacrificial material of the stack of nanowires is etched away outside of a region covered by the dummy gate. The sacrificial material is then selectively etched to form recesses in the sacrificial material layers. Spacers are formed in the recesses in the sacrificial material layers. The dummy gate is etched away with an anisotropic etch. The sacrificial material is etched away to expose the layers of the channel material. A gate stack is formed over and around the layers of the channel material.
