Semiconductor light-emitting device |
摘要 |
A semiconductor light-emitting device comprising a substrate having a surface having an off-angle to a crystallographic plane of low-degree surface orientation, the substrate having thereon: compound semiconductor layers including an active layer; a selective growth protective film formed on the compound semiconductor layers and having an opening at the region corresponding to a stripe region to which a current is injected; and a ridge-shaped compound semiconductor layer fomred to cover the opening. This semiconductor light-emitting device with stable laser property can be manufactured in a simplified way. |
