Title: Semiconductor light-emitting device and its manufacturing method
Inventor: TAKAHASHI TAKASHI
IPC: H01S5/183
Filed: 2002-03-11
Abstract: PROBLEM TO BE SOLVED: To remarkably improve light-emitting characteristics in a semiconductor light-emitting device which is provided with a semiconductor layer containing Al between a substrate and an active layer containing nitrogen. SOLUTION: In a semiconductor light-emitting device, a semiconductor layer (202) containing Al is formed between a substrate (201) and an active layer (204) containing nitrogen. Concentration of oxygen of the active layer (204) containing nitrogen is equal to concentration (e.g. 1×10<18> cm<-3> or less) that the semiconductor light-emitting device can consecutively oscillate at room temperatures. Thus, it is possible to improve light-emitting efficiency of the active layer (204) and to form the semiconductor light-emitting device which can consecutively oscillate at room temperatures.
