  • Light emitting diode element and method of manufacturing the same
    Patent number: 9577148
    Abstract: An n-type GaN layer made of n-type gallium nitride (GaN) is formed on a sapphire substrate. A plurality of island-phased layered structures are formed in random sizes between the n-type GaN layer and a p-type GaN layer that is made of p-type GaN. Each of the layered structures is configured by stacking multiple AlN layers made of aluminum nitride (AlN) and multiple InGaN layers made of indium gallium nitride (InGaN) on an AlN base layer. The respective layered structures emit lights of different wavelengths. This accordingly allows for emission of light in a wider wavelength range.
    Type: Grant
