ABSTRACT:
A method of manufacturing a light emitting diode, which includes the steps of bringing a semiconductor substrate of p-type or n-type into contact with a growth solution at a high temperature and thereafter, lowering the temperature so as to form a monocrystalline epitaxial layer of the same type as the semiconductor substrate on the semiconductor substrate, subsequently, further lowering the above temperature to form a first monocrystalline epitaxial layer of a reverse type to the epitaxial layer on the epitaxial layer and then, cutting off the growth solution to form an epitaxial wafer as a result, a growth solution to contact the first epitaxial layer of a epitaxial wafer at a high temperature, and thereafter, the temperature is lowered to form a second monocrystalline epitaxial layer of the same kind and type as the first epitaxial layer on the first epitaxial layer.
