Abstract: The manufacturing method for the LED for application to FAX or photo copier comprises steps of : (a) epitaxial growth of a p-type AlGaAS(32), a n-type AlGaAS(33) and a n-type GaAS(34) with a fixed thickness in sequence on the GaAS substrate(31); (b) forming ptype region(35) by diffusing Zn at a fixed part of the epitaxial layer; (c) forming an ohmic contact(45) by etching the n-type GaAS(34); (d) forming a P-N junction, which is light emitting region, by etching a part of the p-type AlGaAS(32) and the p-type AlGaAS(32) and the n- type AlGaAS(33);(e) forming a protective film on the top layer;
