ABSTRACT:
A manufacturing method of a light-emitting diode is provided. The light-emitting diode manufactured by the steps of coating solution containing p-type or n-type impurities on a porous silicon layer, thereby forming a p
junction through a thermal treatment has excellent light-emitting efficiency. Also, the process is simple compared to an implantation method, and further the manufacturing is since the thermal treatment can be performed at a relatively low temperature.
