    • The present invention discloses an LED structure, wherein an N-type current spreading layer is interposed between N-type semiconductor layers to uniformly distribute current flowing through the N-type semiconductor layer. The N-type current spreading layer includes at least three sub-layers stacked in a sequence of from a lower band gap to a higher band gap, wherein the sub-layer having the lower band gap is near the substrate, and the sub-layer having the higher band gap is near the light emitting layer. Each sub-layer of the N-type current spreading layer is expressed by a general formula InxAlyGa(1-x-y)N, wherein 0≦x≦1, 0≦y≦1, and 0≦x+y≦1.
    • 本发明公开了一种LED结构,其中N型电流扩展层插入在N型半导体层之间以均匀地分布流过N型半导体层的电流。 N型电流扩展层包括从低带隙到较高带隙的顺序堆叠的至少三个子层,其中具有较低带隙的子层在衬底附近,并且子层 具有较高带隙的发光层靠近发光层。 N型电流扩展层的每个子层由通式In x Al y Ga(1-x-y)N表示,其中0≦̸ x≦̸ 1,0& nlE; y≦̸ 1和0≦̸ x + y≦̸
