Abstract
Disclosed is a light transparent window layer for light transmitting diodes. The light transparent window layer is formed by growing a plurality of AlGaInP superlattice layers such that the uniformity of current distribution within LED chip can be enhanced, and the size of light-emitting area can be increased. The manufacturing process is also simplified.
