Latest Patents
Duk-Jo Kong's latest patents include a groundbreaking invention titled "Ultraviolet light emitting diode and method of manufacturing the same." This patent describes a sidewall light-emitting ultraviolet LED and a method for its production. The invention features a light-emitting structure formed in an active region that is recessed from the substrate surface. The growth of this structure occurs parallel to the substrate surface, allowing for improved light emission. Additionally, a reflective metal layer is strategically placed above or below the light-emitting structure to facilitate the release of ultraviolet light in a direction perpendicular to the growth direction.
Another notable patent is the "Separation method of GaN substrate by wet etching." This method utilizes chemical lift-off techniques to separate a GaN substrate through wet etching. It involves forming oxide layers and GaN columns on a substrate, followed by the creation of an n-GaN layer and subsequent layers for enhanced performance. This innovative approach not only improves the epitaxial growth of GaN but also reduces fabrication costs and increases light extraction efficiency.
