Abstract
Some embodiments include a method of forming an assembly. A first stack of alternating first and second tiers is formed over a conductive structure. A first opening is formed to extend through the first stack. A sidewall of the first opening is lined with a first liner material. The first liner material is converted to a first charge-blocking material. Sacrificial material is formed within the first opening. A second stack of alternating third and fourth tiers is formed over the first stack. A second opening is formed to extend through the second stack to the sacrificial material. A second liner material is formed within the second opening, is anisotropically etched, and is then converted to a second charge-blocking material. The sacrificial material is removed. Charge-storage material, dielectric material and channel material are formed adjacent to the charge-blocking material. Some embodiments include integrated assemblies.
