CONTACT FOR A SEMICONDUCTOR LIGHT EMITTING DEVICE

摘要

An AlGaInP light emitting device is formed as a thin, flip chip device. The device includes a semiconductor structure comprising an AlGaInP light emitting layer disposed between an n-type region and a p-type region. N- and p-contacts electrically connected to the n- and p-type regions are both formed on the same side of the semiconductor structure. The semiconductor structure is connected to the mount via the contacts. The growth substrate is removed from the semiconductor structure and the thick transparent substrate is omitted, such that the total thickness of semiconductor layers in the device is less than 15 mum in some embodiments, less than 10 mum in some embodiments. The top side of the semiconductor structure may be textured.
