LIGHT-EMITTING DIODE ELEMENT

摘要

PROBLEM TO BE SOLVED: To simplify the manufacturing process for manufacturing a wavelength conversion type light-emitting diode element. SOLUTION: A fluorescent material-contg. layer 17 is formed at the bottom surface of a sapphire substrate 12, having an n-type semiconductor 13 and a p-type semiconductor 14 grown on the top surface in one body with the substrate 12, so that the fluorescent material-contg. layer 17 can be settled only by mounting a light-emitting diode element 11 in manufacturing a light-emitting diode. This simplifies the manufacturing process of the light-emitting diode.
