Abstract
Description
technical field
[0001] The invention relates to LED packaging technology, in particular to an LED sealing structure using a transparent oxide substrate and a sealing method thereof. Background technique
[0002] With the continuous development of LED in the field of lighting, people have higher and higher requirements for its light extraction efficiency. LED packaging materials, packaging structures and packaging methods are all important factors affecting its light extraction efficiency; at present, it is mainly through transparent substrate technology. , metal film reflection technology, flip chip technology to improve the light efficiency of LED.
[0003] Usually, blue light and green light LED chips grow GaN (gallium nitride)-based LED chip structure layers on sapphire substrates through MOCVD (metal organic compound chemical vapor deposition) technology, and the light emitted by the P / N junction light-emitting area passes through The upper P-type region is ejected; due...
