Zhongshan LED industry to add new technologies

Sapphire crystal is an important substrate material of blue and white LED, the upstream part of the industry is also LED. Reporter 28, from the Zhongshan Municipal Science and Technology Bureau was informed that the Zhongshan trillion dragon photoelectric sapphire crystal research and development success, and through the technical identification of the new industry, the LED industry has added a new core technology.

It is reported that the sapphire material is the preferred material of the nitride semiconductor substrate, integrated circuit substrate, LED lighting is the wafer and chip products are the most important basic materials, upstream technology products belong to the current international high-end LED chip industry. Sapphire crystal manufacturing in the various sectors of the LED industry chain is a typical technology and equipment threshold high capital intensive industries. Zhongshan trillion dragon core technology team successfully explore a set of 35 kg class, in line with the requirements of the sapphire substrate LED crystal growth process, the core components of the equipment and process technology with independent intellectual property rights.
