Latest Patents

One of his latest patents is titled "Vertical channel transistor and method of fabricating the same." This invention features a vertical channel transistor that includes a plurality of active pillar patterns extending perpendicularly from the substrate's top surface. A gate insulating layer is deposited on the side walls of these active pillar patterns, serving as an ion diffusion barrier between the pillar patterns and the surrounding lower gate electrodes. The structure is encapsulated with metal, and the metal layer is etched back to the height of a sacrificial layer, forming the lower gate electrodes. Additionally, a spacer layer of insulating material is deposited around the upper part of the pillar patterns, and the sacrificial layer is removed to expose part of the lower gate electrodes. This innovative design facilitates semiconductor integration.

Another notable patent is the "Method for fabricating vertical channel transistor." This method involves forming a structure with trimmed pillar patterns, creating a conductive layer for a gate electrode, and performing an etch-back process until the seam is exposed. The gate electrode is then formed by etching the etch-backed conductive layer, showcasing Chun-Hee Lee's expertise in semiconductor fabrication techniques.
