  • Patent number: 10438964
    Abstract: A strap level sacrificial layer and an alternating stack of insulating layers and spacer material layers are formed over a substrate. An array of memory stack structures is formed through the alternating stack and the strap level sacrificial layer. Each memory film in the memory stack structures includes a metal oxide blocking dielectric. After formation of a source cavity by removal of the strap level sacrificial layer, an atomic layer etch process can be employed to remove portions of the metal oxide blocking dielectrics at the level of the source cavity. Outer sidewalls of semiconductor channels in the memory stack structures are exposed by additional etch processes, and a source strap layer is selectively deposited in the source cavity in contact with the semiconductor channel. If the spacer material layers are sacrificial material layers, all volumes of the sacrificial material layers can be replaced with the electrically conductive layers.

  • Patent number: 10381376
    Abstract: A three-dimensional memory device includes alternating stacks of insulating strips and electrically conductive strips located over a substrate and laterally spaced apart among one another by vertically undulating trenches. The vertically undulating trenches have a greater lateral extent at levels of the electrically conductive strips than at levels of the insulating strips. An interlaced two-dimensional array of memory stack assemblies and dielectric pillar structures are located in the vertically undulating trenches. Each memory stack assembly includes a vertical semiconductor channel and a pair of memory films including a respective pair of convex outer sidewalls that contact, or are spaced by a uniform distance from, concave sidewalls of the electrically conductive strips.

  • Patent number: 10381364
    Abstract: A three-dimensional memory device can be formed by first forming an alternating stack of insulating layers and stack level spacer material layers over a substrate. The stack level spacer material layers can be formed as, or are subsequently replaced with, stack level electrically conductive layers. A bottommost insulating spacer layer is formed with recesses that form grooves that are laterally spaced apart. Drain select level electrically conductive layers are formed over protruding portions and within the grooves of the bottommost insulating spacer layer by anisotropic deposition and isotropic etch back of a conductive material. Additional insulating spacer layers may be formed by anisotropic deposition of an insulating material. Additional drain select level electrically conductive layers can be formed by anisotropic deposition and isotropic etch back of additional conductive material.

  • Patent number: 10355007
    Abstract: A memory stack structure includes a cavity including a back gate electrode, a back gate dielectric, a semiconductor channel, and at least one charge storage element. In one embodiment, a line trench can be filled with a memory film layer, and a plurality of semiconductor channels can straddle the line trench. The back gate electrode can extend along the lengthwise direction of the line trench. In another embodiment, an isolated memory opening overlying a patterned conductive layer can be filled with a memory film, and the back gate electrode can be formed within a semiconductor channel and on the patterned conductive layer. A dielectric cap portion electrically isolates the back gate electrode from a drain region. The back gate electrode can be employed to bias the semiconductor channel, and to enable sensing of multinary bits corresponding to different amounts of electrical charges stored in a memory cell.

  • Patent number: 10355015
    Abstract: A memory device includes an alternating stack of insulating layers and electrically conductive layers. Vertical NAND strings are formed through the alternating stack, each of which includes a drain region, memory cell charge storage transistors, and a pair of drain select transistors in a series connection. A common bit line is electrically connected to drain regions of two vertical NAND strings. The drain select transistors of the two vertical NAND strings are configured such that drain select transistors sharing a first common drain select gate electrode provide a higher threshold voltage for one of the two vertical NAND strings, and drain select transistors sharing a second common drain select gate electrode provide a higher threshold voltage for the other of the two vertical NAND strings. The different threshold voltages can be provided by a combination of a masked ion implantation and selective charge injection.
