Описание продукта
The LED epitaxial wafer is a substrate heated to an appropriate temperature. The LED wafer material is the cornerstone of the technology development for the semiconductor lighting industry. Different substrate materials require different LED epitaxial wafer growth technology, chip processing technology and device packaging technology. The substrate for LED epi wafer determines the development route of semiconductor lighting technology. To achieve luminous efficiency, epitaxial wafer suppliers pay more attention to GaN based LED epitaxial wafer, since the epitaxial wafer price is in low cost, and the epi wafer defect density is small. LED epi wafer advantage on GaN substrate is the realization of high efficiency, large area, single lamp and high power, which make the process technology simplify and improve the large yield rate. The development prospects of the LED epi wafer market are optimistic.
