摘要： A thin film of SiO.sub.2 is patterned on an N layer consisting of N-type Al.sub.x Ga.sub.1-x N (inclusive of x=0). Next, I-type Al.sub.x Ga.sub.1-x N (inclusive of x=0) is selectively grown and the portion on the N layer grows into an I-layer consisting an active layer of a light emitting diode, and that on the SiO.sub.2 thin film grows into a conductive layer. Electrodes are formed on the I-layer and conductive layer to constitute the light emitting diode. Also, on the surface a ({1120}) of a sapphire substrate, a buffer layer consisting of aluminum nitride is formed, onto which a gallium nitride group semiconductor is formed.

摘要： A substrate for producing a gallium nitride compound-semiconductor (Al.su Ga.sub.1-x N; X=0 inclusive) device in vapor phase on a sapphire substrate using gaseous organometallic compound, and a also blue light emitting diode produced by using the substrate. The buffer layer comprising aluminium nitride (AlN) and having a crystal structure where microcrystal or polycrystal is mixed in amorphous state, is formed on the sapphire substrate. The buffer layer is formed at a growth temperature of 380.degree. to 800.degree. C. to have a thickness of 100 to 500 .ANG.. Further, on the buffer layer is formed the layer of gallium nitride compound-semiconductor (Al.sub.x Ga.sub.1-x N; X=0 inclusive). The layer of gallium nitride compound-semiconductor (Al.sub.x Ga.sub.1-x N; X=0 inclusive) comprising at least two layers having different conductive types and being sequentially layered on the buffer layer, functions as a light emitting layer. The existence of the buffer layer having the aforementioned structure greatly contributes on the improved high-quality single crystal of the gallium nitride compound-semiconductor. On the other hand, the blue light emitting property is also improved due to the increase of the quality.
