Zhongshan LED industry adds new substrate technology

Sapphire crystals are important substrate materials for blue and white LEDs and are an upstream link in the LED industry. The reporter learned from the Zhongshan Science and Technology Bureau on the 28th that the sapphire crystal developed by Zhongshan Zhaolong Optoelectronics Co., Ltd. was successfully tested and passed the technical appraisal, adding a new core technology to the Zhongshan LED industry.
It is reported that sapphire material is the preferred material for nitride semiconductor substrate and integrated circuit substrate. It is the most important basic material for LED illumination epitaxial wafer and chip products, and belongs to the upstream technology products of the current international high-end LED chip industry. Sapphire crystal manufacturing is a typical capital-intensive industry with high technology and equipment barriers in all aspects of the LED industry chain. The core technical team of Zhongshan Zhaolong Optoelectronics successfully explored a 35-kilogram sapphire crystal growth process that meets the requirements of LED substrate. The core components and process technology of the device have their own intellectual property rights.
