Latest Patents

One of Lin's latest patents is focused on a vertical light-emitting diode (VLED). This invention describes a VLED and its manufacturing method that utilizes a combination of a reflective layer, a transparent conducting layer, and a transparent dielectric layer. These structural layers promote uniform current distribution and enhance light extraction. In this VLED, a transparent conducting layer is formed on the first outer surface of a stack of multiple group III nitride semiconductor layers. A transparent dielectric layer is then created on the side of the transparent conducting layer that is opposite the multi-layer structure. Additionally, a first electrode structure is formed on the transparent dielectric layer, establishing electrical contact with the transparent conducting layer through a series of contact windows patterned through the dielectric layer. The use of these layers significantly improves light extraction.

Another patent by Lin details a method for manufacturing a vertical type light-emitting diode. In this method, a multilayered structure of group III nitride semiconductor compounds is epitaxially deposited on an irregular surface of a substrate. The substrate is subsequently removed to reveal an irregular surface of the multilayered structure that corresponds to the substrate's irregular surface. A portion of this exposed irregular surface is then etched to create an electrode contact surface, where an electrode layer is later formed. This innovative method eliminates the need for a specific planarized region on the substrate's irregular surface, thus avoiding the necessity for planarization treatment. The same substrate can be reused for fabricating both vertical and horizontal light-emitting diodes.
