Zhongshan LED sapphire crystal growth project through technical identification

Zhongshan LED new light source industry value chain from low-end to high-end development has important technical support. The day before, in Zhongshan Zhaolong photoelectric Co Ltd "Municipal Science and Technology Bureau held the LED sapphire crystal growth technology appraisal meeting, the company's" LED crystal "project through technical appraisal. After more than 3 months of fighting, by the Zhongshan trillion dragon R & D sapphire crystal was finally successful in Zhongshan.

Experts agreed that the project product technical indicators in line with the requirements of the LED substrate, the growth of LED sapphire crystal technology reached the international advanced level, with the ability to implement industrialization. Sapphire crystal successful trial production, highlighting the Dragon photoelectric have considerable strength in LED sapphire technology, marking the city for the LED lighting industry in the process of bigger, to seize the high-end industrial chain has taken an important step.

According to reports, the sapphire material is the material of choice for integrated circuit substrate, a nitride semiconductor substrate, is the current LED lighting wafer and chip products are the most important basic materials, upstream technology products belong to the current international high-end LED chip industry, in all aspects of the LED industry chain is a typical capital intensive industry technology and equipment of high threshold the. The core technology team Zhongshan Zhaolong photoelectric by optimizing growth furnace thermal field transformation crystal, vacuum system, mechanical and control system, optimization of kyropoulos sapphire crystal growth of the seed, shoulder, diameter, closure and cooling process parameters, successfully worked out a set of 35 kg with sapphire crystal LED substrate for growth process. The core components of the equipment and process technology with independent intellectual property rights.
