    摘要: The present invention relates to an LED, in which an n-doped semiconductor layer, an active layer, a p-doped semiconductor layer and a p-electrode are formed in their order on a sapphire substrate. A high reflectivity material layer containing Cu and Si is deposited on a remaining partial region of the n-doped semiconductor layer. An n-electrode is formed on the high reflectivity material layer. The high reflectivity material layer formed between the n-electrode and the partial region of the underlying n-doped semiconductor layer can reflect light toward a substrate, thereby improving the luminous efficiency of the LED.
