Methods of forming NAND memory arrays

Abstract:

Some embodiments include device having a gate spaced from semiconductor channel material by a dielectric region, and having nitrogen-containing material directly against the semiconductor channel material and on an opposing side of the semiconductor channel material from the dielectric region. Some embodiments include a device having a gate spaced from semiconductor channel material by a dielectric region, and having nitrogen within at least some of the semiconductor channel material. Some embodiments include a NAND memory array which includes a vertical stack of alternating insulative levels and wordline levels. Channel material extends vertically along the stack. Charge-storage material is between the channel material and the wordline levels. Dielectric material is between the channel material and the charge-storage material. Nitrogen is within the channel material. Some embodiments include methods of forming NAND memory arrays.
