VERTICAL NON-VOLATILE MEMORY DEVICES HAVING A MULTI-STACK STRUCTURE WITH ENHANCED PHOTOLITHOGRAPHIC ALIGNMENT CHARACTERISTICS - A simplified explanation of the abstract
This abstract first appeared for US patent application 18402144 titled 'VERTICAL NON-VOLATILE MEMORY DEVICES HAVING A MULTI-STACK STRUCTURE WITH ENHANCED PHOTOLITHOGRAPHIC ALIGNMENT CHARACTERISTICS
Simplified Explanation
The abstract describes a vertical-type nonvolatile memory device with a multi-stack structure that reduces susceptibility to misalignment of a vertical channel layer. The device includes a main chip area with a stepped structure, a cell area, and an extension area formed in a multi-stack structure, as well as an outer chip area surrounding the main chip area with a step key.
- The main chip area of the nonvolatile memory device includes a cell area and an extension area arranged in a multi-stack structure.
- The main chip area has a stepped structure, with a first layer on a substrate and a second layer on the first layer.
- A lower vertical channel layer is arranged in the first layer, while the step key in the outer chip area includes an alignment vertical channel layer with a top surface lower than the lower vertical channel layer.

Original Abstract Submitted
A vertical-type nonvolatile memory device has a multi-stack structure with reduced susceptibility to mis-alignment of a vertical channel layer. This nonvolatile memory device includes: (i) a main chip area including a cell area and an extension area arranged to have a stepped structure, with the cell area and the extension area formed in a multi-stack structure, and (ii) an outer chip area, which surrounds the main chip area and includes a step key therein. The main chip area includes a first layer on a substrate and a second layer on the first layer. A lower vertical channel layer is arranged in the first layer. The step key includes an alignment vertical channel layer, and a top surface of the alignment vertical channel layer is lower than a top surface of the lower vertical channel layer.
