METHOD FOR FABRICATING GAN FILM AND SUBSTRATE FOR FABRICATING GAN FILM

摘要

PURPOSE: A method for manufacturing gallium nitride and a gallium nitride film board are provided to prevent cracks on a nitride film due to changed material property. CONSTITUTION: A method for manufacturing gallium nitride comprises the following steps. From the inside of a board, a gallium nitride(GaN) atom and an atom of the board are mixed to form a mixture layer(S110). Gallium nitride is grown on the board(S120).
