Abstract

A lateral thermal dissipation LED and a fabrication method thereof are provided. The lateral thermal dissipation LED utilizes a patterned metal layer and a lateral heat spreading layer to transfer heat out of the LED. The thermal dissipation efficiency of the LED is increased, and the lighting emitting efficiency is accordingly improved.
