Patent ID: 8278129

Claim:
A process of fabricating a nitride semi-conductor light emission layer of AlGaInN that is set to emit light having its wavelength of 250 to 300 nm, said nitride semi-conductor light emission layer comprising a well layer of Al a Ga b In (1-a-b) N(0<a<1, 0<b<1, 1−a−b>0) and a barrier layer of Al c Ga f In (1-c-f) N(0 <e<1, 0<f<1, 1−e−f>0, e>a), wherein said well layer is fabricated by growing at a growth rate less than 0.09 μm/h according to the metal organic vapor phase epitaxy (MOVPE) method, and wherein said barrier layer is fabricated by growing at a growth rate less than 0.09 μm/h according to the metal organic vapor phase epitaxy (MOVPE) method.
