摘要： An electric contact structure adopted for an LED comprises a nitride middle layer and an N-type metal electrode layer. The LED includes an N-type semiconductor layer, a light emission layer and a P-type semiconductor layer that are stacked to form a sandwich structure. The nitride middle layer is patterned and formed on the N-type semiconductor layer. The N-type metal electrode layer is formed on the nitride middle layer and prevented from being damaged by diffusion of the metal ions as the nitride middle layer serves as a blocking interface, thus electric property of the N-type semiconductor layer can be maintained stable. The nitride middle layer would not be softened and condensed due to long-term high temperature, thereby is enhanced adhesion. Moreover, the N-type metal electrode layer further can be prevented from peeling off, hence is increased the lifespan of the LED.

摘要： A method for separating a light-emitting diode (LED) from a substrate comprises the following steps. First, a substrate is provided which includes a junction surface and a bottom surface far away from the junction surface. Then a plurality holes are formed on the junction surface. An LED structure is further grown on the junction surface, and includes a junction portion bonded to the junction surface. The bottom surface is then polished to be shrunk to communicate with the holes. Finally, the junction portion is etched by an etching liquid via the holes to separate the LED structure from the substrate. Accordingly, by forming the holes, the LED structure and the substrate can be separated through polishing and etching processes, thereby providing a high yield rate as well as reduced production costs.

摘要： A light-emitting diode (LED) with a mirror protection layer includes sequentially stacked an N-type electrode, an N-type semiconductor layer, a light-emitting layer, a P-type semiconductor layer, a metal mirror layer, a protection layer, a buffer layer, a binding layer, a permanent substrate, and a P-type electrode. The protection layer is made of metal oxide, and has a hollow frame for covering or supporting edges of the metal mirror layer. Accordingly, the metal mirror layer can be protected by the protection layer to prevent from oxidation in subsequent processes and to prevent metal deterioration during high-current operations. Thus the metal mirror layer can maintain high reflectivity, thereby increasing light extraction efficiency and electrical stability of the LED.

摘要： An LED with a current diffusion structure comprises an N-type semiconductor layer, a light emitting layer, a P-type semiconductor layer, an N-type electrode, a P-type electrode and a current blocking layer. The N-type semiconductor layer, light emitting layer and P-type semiconductor layer form a sandwich structure. The N-type and P-type electrodes are respectively arranged on the N-type and P-type semiconductor layers. The current blocking layer has the pattern of the N-type electrode and is embedded inside the N-type semiconductor layer. Thereby not only current generated by the N-type electrode detours the current blocking layer and uniformly passes through the light emitting layer, but also prevents interface effect to increase impedance. Thus is promoted lighting efficiency of LED. Further, as main light-emitting regions of the light emitting layer are far from the N-type electrode, light shielded by the N-type electrode is reduced and illumination of LED is thus enhanced.
摘要翻译：具有电流扩散结构的LED包括N型半导体层，发光层，P型半导体层，N型电极，P型电极和电流阻挡层。 N型半导体层，发光层和P型半导体层形成夹层结构。 N型和P型电极分别设置在N型和P型半导体层上。电流阻挡层具有N型电极的图案，并且嵌入在N型半导体层的内部。因此，不仅由N型电极产生的电流绕过电流阻挡层并均匀地通过发光层，而且防止了界面效应增加阻抗。从而提高了LED的照明效率。此外，随着发光层的主要发光区域远离N型电极，由N型电极屏蔽的光减少，因此LED的照明得到增强。

摘要： A tension release layer structure is applied to an LED which includes a P-type electrode, a permanent substrate, a binding layer, a tension release layer, a mirror layer, a P-type semiconductor layer, a light-emitting layer, an N-type semiconductor layer and an N-type electrode that are stacked in sequence. The tension release layer is made of a complex material including at least two material elements with boundaries that are blended with each other. As the complex material in the tension release layer does not have apparent interface separation, stress between interface effect and materials can be eliminated to increase light-emitting efficiency and production yield of the LED.

摘要： A thermal stress releasing structure is applied to a light-emitting diode (LED) which includes a P-type electrode, a permanent substrate, a binding layer, a buffer layer, a mirror layer, a P-type semiconductor layer, a light-emitting layer, an N-type semiconductor layer, and an N-type electrode that are stacked in sequence. The buffer layer includes a plurality of first material layers and a plurality of second material layers. The first material layers and the second material layers are alternately stacked in a staggered manner to form a concave-convex structure in a stacking direction of the first and second material layers. The concave-convex structure is formed in a corrugated shape to function as the thermal stress releasing structure, thus is capable of releasing thermal stress generated by thermal expansion and contraction of the buffer layer in the LED to prevent the buffer layer from damaging a metal layer or an epitaxy layer.

摘要： A reflection convex mirror structure is applied to a vertical light-emitting diode (LED) which comprises a P-type electrode, a permanent substrate, a binding layer, a buffer layer, a mirror layer, a P-type semiconductor layer, a light-emitting layer, an N-type semiconductor layer and an N-type electrode that are stacked in sequence. Between the P-type semiconductor layer and the mirror layer, a filler and a mirror are disposed right below the N-type electrode. The filler is made of a transparent material and has a convex surface facing the light-emitting layer. The mirror is formed on the convex surface of the filler. By utilizing the filler and the mirror to form the reflection convex mirror structure, excited light is reflected towards two sides, so that the excited light can dodge the N-type electrode without being shielded to increase light extraction efficiency.
