SEMICONDUCTOR LIGHT EMITTING ELEMENT AND MANUFACTURE THEREOF

摘要

PURPOSE:To evenly inject current into the whole active layer for emitting light from the whole active layer while making the light emitted from the active layer hardly shadowed by an electrode as well as making the light hardly reflected on the inner part of the surface of a lighting layer for increasing the output from the title semiconductor light emitting element. CONSTITUTION:A diffusing agent layer 6 working as a non-reflective coated film and meeting the non-reflection requirements is provided on the surface of an upper clad layer 5. Next, impurities are diffused from the diffusing agent layer 6 in the upper clad layer 5 so as to form a high concentration semiconductor region 7 in the upper clad layer 5.
