Abstract:
In a 3D NAND device, the charge trap region of a memory cell is formed as a separate charge-trap “island.” As a result, the charge-trap region of one memory cell is electrically isolated from charge-trap regions in adjacent memory cells. The charge trap region of one memory cell is separated from the charge trap regions of adjacent memory cells by a dielectric structure, such as a silicon oxide film. Alternatively, the charge trap region of a memory cell is separated from the charge trap regions of adjacent memory cells by an air, gas, or vacuum gap.

Claim (Index 11):
A three-dimensional NAND device comprising:\n a first nonvolatile memory cell that includes: a first charge trap layer having a first surface and a second surface, the first surface of the first charge trap layer contacting a surface of a gate oxide layer, the second surface of the first charge trap layer contacting a first surface of a first blocking oxide layer; a first diffusion barrier layer having a first surface and a second surface, the first surface of the first diffusion barrier layer contacting a second surface of the first blocking oxide layer; a first conductive semiconductor layer having a first surface and a second surface, the first surface of the first conductive semiconductor layer contacting the second surface of the first diffusion barrier layer; and a first control gate contacting the second surface of the first conductive semiconductor layer; and a second nonvolatile memory cell that is adjacent to the first nonvolatile memory cell and includes: a second charge trap layer having a first surface and a second surface, the first surface of the second charge trap layer contacting the surface of a gate oxide layer, the second surface of the second charge trap layer contacting a first surface of a second blocking oxide layer, wherein the second charge trap layer and the first charge trap layer are physically separated from each other by a gap.
