Latest Patents

One of Jin-Hae Choi's latest patents is titled "Nonvolatile memory device and method of fabricating the same." This technology involves a nonvolatile memory device that includes a pipe connection gate electrode over a substrate. The device features one or more pipe channel layers formed within the gate electrode, along with pairs of main channel layers that extend perpendicularly to the substrate. Additionally, it incorporates a plurality of interlayer insulating layers and cell gate electrodes that are alternately stacked along the main channel layers. The design also includes etch stop layers made of metal silicide, which are formed over the pipe connection gate electrode.

Another patent by Jin-Hae Choi, also titled "Nonvolatile memory device and method of fabricating the same," presents a similar concept. In this invention, the pipe connection gate electrode is configured with a bottom buried in a groove formed in the substrate. The device includes pipe channel layers and main channel layers, along with interlayer insulating layers and cell gate electrodes. A key feature of this design is the inclusion of a metal silicide layer within the groove, which significantly reduces the electric resistance of the pipe connection gate electrode without increasing its height.
