GALLIUM NITRIDE SUBSTRATE AND OPTICAL DEVICE USING THE SAME |
摘要 |
A method of processing a gallium nitride substrate, includes providing a gallium nitride substrate, polishing a surface of the gallium nitride substrate, and cleaning the polished surface of the gallium nitride substrate. The polished surface includes a GaLα/CKα peak intensity ratio in energy dispersive X-ray microanalysis (EDX) spectrum which is not less than 2, the EDX spectrum being obtained in an EDX of the surface of the gallium nitride substrate using a scanning electron microscope (SEM) at an accelerating voltage of 3 kV. |
