Abstract:
A method for fabricating an infrared-emitting light-emitting diode, which comprises:applying an active layer sequence on a semiconductor substrate, the active layer sequence emitting infrared radiation during operation of the active layer sequence, the active layer sequence, includes: forming a first AlGaAs cover layer on the semiconductor substrate using a metal organic vapor phase epitaxy (MOVPE) fabrication method; forming an active layer on the first AlGaAs cover layer using the MOVPE fabrication method; forming a second AlGaAs cover layer on the active layer using a liquid phase epitaxy (LPE) fabrication method; â€ƒand depositing an electrically conductive coupling-out layer having a thickness of at least about 10 &mgr;m and being optically transparent in an infrared spectral region on the second AlGaAs cover layer using the LPE fabrication method.
