Patent ID: 8148178

Claim:
A method of growing a nitride single crystal, the method comprising: growing a first nitride single crystal layer on a substrate; forming a dielectric pattern having an open area on the first nitride single crystal layer, the open area exposing a part of an upper surface of the first nitride single crystal layer; and growing a second nitride single crystal layer on the first nitride single crystal layer through the open area while the second nitride single crystal layer is grown to be smaller than or equal to a height of the dielectric pattern, wherein the height of the dielectric pattern is greater than a width of the open area so that dislocations in the second nitride single crystal layer move laterally, collide with side walls of the dielectric pattern, and are terminated, wherein the growing the second nitride single crystal layer comprises: performing vertical growth preceding lateral growth of the second nitride single crystal; and performing lateral growth preceding vertical growth after performing the vertical growth so that dislocations in the second nitride single crystal collide with the side walls of the dielectric pattern, and are terminated.
