Abstract
A surface-emitting AlGaInP LED is disclosed. The LED uses a GaP layer as a window layer to eliminate the current crowding effect, or may has an ITO window layer and use GaP, instead of GaAs, as the substrate to eliminate the current-crowding effect and avoid the emitted light being absorbed by the substrate. The GaP layer is bonded to the double hetero-structure epitaxy layer by a wafer bonding technique. The present invention, however, provides a manufacturing procedure which is easier and more reliable to handle than prior arts.
