Abstract
A light emitting diode (LED) and a method of making the same are disclosed. The present invention uses a metal layer of high conductivity and high reflectivity to prevent the substrate from absorbing the light emitted. This invention also uses the bonding technology of dielectric material thin film to replace the substrate of epitaxial growth with high thermal conductivity substrate to enhance the heat dissipation of the chip, thereby increasing the performance stability of the LED, and making the LED applicable under higher current.
