Example Embodiment
[0064] In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings.
[0065] figure 1 It is a schematic cross-sectional view of a light emitting diode in an embodiment of the invention.
[0066] Please refer to figure 1 The light emitting diode 200 includes a substrate 210, an N-type semiconductor layer 220, an active layer 230, a P-type semiconductor layer 240, and a first electrode 250 and a second electrode 260. The substrate 210 is, for example, a sapphire substrate. Specifically, a nitride semiconductor cladding layer 212 (for example, undoped gallium nitride), an N-type semiconductor layer 220, an active layer 230, and a P-type semiconductor layer 240 are sequentially formed on a surface of the sapphire substrate 210 The active layer 230 is located between the N-type semiconductor lay...
