Embodiment Construction
[0062] Please refer to Figure 2A to Figure 2E , which shows a process cross-sectional view of a light emitting diode structure according to an embodiment of the present invention. In this embodiment, first, a transparent substrate 200 is provided. The material of the substrate 200 can be, for example, sapphire. Next, the buffer layer 202 is selectively formed on the substrate 200 by epitaxy, such as metal organic chemical vapor deposition (MOCVD). The material of the buffer layer 202 can be an undoped semiconductor, such as undoped gallium nitride series materials. Next, a light-emitting epitaxial structure is grown on the buffer layer 202 by means of epitaxy, such as metalorganic chemical vapor deposition. In this embodiment, the light emitting epitaxial structure may include the first electrical type semiconductor layer 204 , the light emitting layer 210 and the second electrical type semiconductor layer 212 stacked on the buffer layer 202 in sequence. Wherein, the firs...
