LIGHT EMITTING DIODE WITH ENHANCED LIGHT EXTRACTION

摘要

A light-emitting diode includes a substrate, a stacked semiconductor structure on one side of the substrate, and a reflection layer on the other side of the substrate opposite to the stacked semiconductor structure. At least one contact electrode is disposed on the stacked semiconductor structure. The contact electrode includes a pad electrode and at least one finger electrode extending from the pad electrode. A light-guiding structure is disposed along the finger electrode.
