Abstract

A method of manufacturing a nitride semiconductor substrate according to example embodiments may include forming a buffer layer on a (100) plane of a silicon (Si) substrate. The buffer layer may have a hexagonal crystal system and a (1010) plane. A nitride semiconductor layer may be epitaxially grown on the buffer layer. The nitride semiconductor layer may have a (1010) plane. Accordingly, because example embodiments enable the use of a relatively inexpensive Si substrate, a more economical nitride semiconductor substrate having a relatively large diameter may be achieved.
