Abstract:
A method of fabricating a light emitting device using a wafer level package process and a light emitting device fabricated by the same are disclosed. The light emitting device has improved heat dissipation to prevent damage by heat, thereby achieving improvement in reliability and luminous efficacy. In addition, the light emitting device has a small difference in coefficient of thermal expansion and thus can reduce stress applied to a light emitting structure to prevent damage to the light emitting structure, thereby achieving improvement in reliability and luminous efficacy.
