Latest Patents
One of his latest patents is a method for manufacturing aluminum nitride-based transistors. This invention relates to a method of producing an AlN-based high electron mobility transistor (HEMT) element. The design incorporates an AlN buffer layer and an AlGaN composition change layer, which is inserted into a GaN/AlN interface. This configuration effectively reduces the generation of a two-dimensional hole gas (2DHG), thereby enhancing the mobility of the two-dimensional electron gas (2DEG) layer.
Another significant patent by Ui Ho Choi is a method for manufacturing diamond substrates. This invention focuses on a technique for growing diamond after forming an air gap structure that has a crystal correlation with a lower substrate. By utilizing heat treatment of a photoresist pattern and an air gap forming film material on substrates such as sapphire, the process is simplified and costs are reduced. This method allows for the high-quality growth of large-area single crystal diamond substrates while minimizing defects and cracks.
