NITRIDE BASED LIGHT EMITTING DIODE WITH EXCELLENT EFFECT OF BLOCKING LEAKAGE CURRENT AND MANUFACTURING METHOD THEREOF

摘要

PURPOSE: A nitride based light emitting diode with excellent leakage current blocking effect and a manufacturing method thereof are provided to improve the light efficiency by forming a current blocking part. CONSTITUTION: A current blocking part(220) is made of an insulating material. The current blocking part is arranged between a substrate and an n-type nitride layer(230). An active layer(240) is formed on the n-type nitride layer. A p-type nitride layer is formed on the active layer. The substrate has an upper surface.
