  • Patent number: 9935000
    Abstract: A disclosed example to modulate slit stress in a semiconductor substrate includes controlling a first process to apply a first material to a semiconductor substrate. The semiconductor substrate includes a slit between adjacent stacked transistor layers. The first material coats walls of the slit to reduce a first width of the slit between the adjacent stacked transistor layers to a second width. A second process is controlled to apply a second material to the semiconductor substrate. The second material is to be deposited in the second width of the slit. The first material and the second material are to form a solid structure in the slit between the adjacent stacked transistor layers.

  • Patent number: 8575716
    Abstract: A method of forming memory array and peripheral circuitry isolation includes chemical vapor depositing a silicon dioxide-comprising liner over sidewalls of memory array circuitry isolation trenches and peripheral circuitry isolation trenches formed in semiconductor material. Dielectric material is flowed over the silicon dioxide-comprising liner to fill remaining volume of the array isolation trenches and to form a dielectric liner over the silicon dioxide-comprising liner in at least some of the peripheral isolation trenches. The dielectric material is furnace annealed at a temperature no greater than about 500° C. The annealed dielectric material is rapid thermal processed to a temperature no less than about 800° C. A silicon dioxide-comprising material is chemical vapor deposited over the rapid thermal processed dielectric material to fill remaining volume of said at least some peripheral isolation trenches.

  • Patent number: 8450218
    Abstract: A method of forming silicon oxide includes depositing a silicon nitride-comprising material over a substrate. The silicon nitride-comprising material has an elevationally outermost silicon nitride-comprising surface. Such surface is treated with a fluid that is at least 99.5% H2O by volume. A polysilazane-comprising spin-on dielectric material is formed onto the H2O-treated silicon nitride-comprising surface. The polysilazane-comprising spin-on dielectric material is oxidized to form silicon oxide. Other implementations are contemplated.

  • Patent number: 8030170
    Abstract: Some embodiments include methods of forming isolation structures. A trench may be formed to extend into a semiconductor material. Polysilazane may be formed within the trench, and then exposed to steam. A maximum temperature of the polysilazane during the steam exposure may be less than or equal to about 500° C. The steam exposure may convert all of the polysilazane to silicon oxide. The silicon oxide may be annealed under an inert atmosphere. A maximum temperature of the silicon oxide during the annealing may be from about 700° C. to about 1000° C. In some embodiments, the isolation structures are utilized to isolate nonvolatile memory components from one another.
