摘要： The present invention relates to a method of manufacturing an AlN-based transistor. An AlN-based high electron mobility transistor (HEMT) element according to the present invention may use an AlN buffer layer, and include an AlGaN composition change layer inserted into a GaN/AlN interface to remove or suppress a degree of generation of a two-dimensional hole gas (2DHG), thereby decreasing an influence of a coulomb drag on a two-dimensional electron gas (2DEG) layer and improving mobility of a two-dimensional electron gas (2DEG).

摘要： The present invention relates to a method for manufacturing a diamond substrate, and more particularly, to a method of growing diamond after forming a structure of an air gap having a crystal correlation with a lower substrate by heat treatment of a photoresist pattern and an air gap forming film material on a substrate such as sapphire (Al2O3). Through such a method, a process is simplified and the cost is lowered when large-area/large-diameter single crystal diamond is heterogeneously grown, stress due to differences in a lattice constant and a coefficient of thermal expansion between the heterogeneous substrate and diamond is relieved, and an occurrence of defects or cracks is reduced even when a temperature drops, such that a high-quality single crystal diamond substrate may be manufactured and the diamond substrate may be easily self-separated from the heterogeneous substrate.
