摘要: A light emitting diode array comprises compound semiconductor layers epitaxially grown on a p-type GaAs conductive layer 11 formed on a semi-insulating GaAs substrate 30. The epitaxial layer is isolated and divided into a plurality of light emitting parts 1 which function as a light emitting diode. A Si-doped n-type GaAs buffer layer 31 is interposed between the semi-insulating GaAs substrate 30 and the p-type GaAs conductive layer 11. In the light emitting diode array comprising this epitaxial configuration, it is possible to prevent the short-circuit defect due to diffusion of p-type dopant from the p-type GaAs conductive layer into the semi-insulating GaAs substrate made by the LEC method.

摘要: A LED monolithic array type like emitting device which has a plurality of light emitting parts. The device is particularly suitable as a light source for printers. Each light emitting part has a light emitting diode having a laminate structure.
