    摘要: In the light-emitting gallium-nitride-group compound semiconductor devices using a substrate, the operating voltage is lowered and at the same time the occurrence of crack during crystal growth is suppressed, resulting in an improved manufacturing yield rate. The device includes a stacked structure of an n-type layer, a light-emitting layer and a p-type layer formed in the foregoing order on a substrate, and an n-side electrode formed on the surface of the n-type layer. The n-type layer is a laminate layer composed of, in the order from the substrate, first n-type layer and a second n-type layer having a carrier concentration higher than that of the first n-type layer. As the contact resistance between the n-type layer and the n-side electrode formed thereon is reduced, the operating voltage of a light-emitting device is lowered, and the power consumption decreased.

    摘要: A gallium-nitride-group compound-semiconductor light-emitting device having an improved luminous intensity that makes it more suitable for use in the full-color outdoor display of an advanced performance. A gallium-nitride-group compound-semiconductor light-emitting device comprising an n-type layer 3, a light-emitting layer 4 and p-type layers 5, 6, the light-emitting layer 4 is doped with a p-type impurity, Mg for example, in a certain specific concentration, so a pn junction is formed within the light-emitting layer 4 and a light emission caused by the electron transition between conduction band and valence band is obtained. In a GaN group compound-semiconductor light-emitting device comprising at least an n-type clad layer 3, a p-type clad layer 5 and a light-emitting layer formed in between the clad layers 3, 5, stacked on a substrate 1. The light-emitting layer 4 is structured as a substance of stacked layers including an n-type layer 41 and a p-type layer 42, or these layers plus an i-type layer formed in between the layers 41 and 42, so a pn junction is formed within the light-emitting layer 4 itself. The injection of electrons and holes into the light-emitting layer 4 is expedited and the luminous intensity of the light-emitting layer 4 is increased.

    摘要: In a semiconductor light emitting device, light is lost from a side surface of a substrate; therefore, if a substrate side surface occupies a large area, it decreases light extraction efficiency. The area of the substrate side surface may be reduced by reducing a thickness of the substrate. However, a thin substrate has low mechanical strength and is cracked by a stress during work process, and that decreases the yield.A light emitting layer is formed on a substrate. After fixed to a grinding board with wax, the substrate is ground to thin. A support substrate is then bonded to the substrate for reinforcement. The substrate is fixed to an electrode and others, with the support substrate bonded to the substrate. The support substrate is lastly removed.
