Latest Patents

One of Changsub Lee's latest patents is for a three-dimensional semiconductor memory device. This device features a stack structure that includes gate structures and first dielectric patterns that are alternately stacked. It also incorporates a vertical channel that penetrates the stack structure, along with a charge storage layer that extends from between the vertical channel and the first gate structures to between the vertical channel and the first dielectric patterns. The gate structures consist of first gate structures with top and bottom surfaces facing each other, differing in width. The charge storage layer is designed with first segments between the vertical channel and the first gate structures, and second segments between the vertical channel and the first dielectric patterns, with the first segments being thicker than the second segments.

Another notable patent is for a semiconductor device that includes a substrate and vertically stacked gate electrodes. Insulating patterns are placed between the gate electrodes, and an active pillar penetrates both the gate electrodes and the insulating patterns, electrically coupling with the substrate. A memory pattern is situated between the gate electrodes and the active pillar, as well as between the insulating patterns and the active pillar. The gate electrodes feature edge portions that extend between the memory pattern and the insulating patterns.
