Abstract：

In　this　paper,　we　simulate　the　relationship　between　the　reflectivity　and　the　light　incident　angle.　When　the　incident　angle　is　more　than　23°,　the　light　can　not　be　extracted　from　LED　top　emitting　surface.　We　fabricate　SiON　and　SiNx　films　respectively　at　low　temperature　(100　°C)　through　Plasma　Enhanced　Chemical　Vapor　Deposition　(PECVD)　to　serve　as　the　passivation　layer　of　GaN-LEDs,　and　then　compare　their　light　output　power.　The　light　output　power　of　the　LED　improved　greatly　after　depositing　the　SiON　passivation　layer.
