April 11, 2013 -12, 2013 China LED industry health development forum will be held in Shenzhen Convention and Exhibition center. Chinese LED industry healthy development forum is sponsored by the Chinese /LED semiconductor lighting industry and union, following the high standards and high level of activity in 2012 two /LED semiconductor lighting standard Publicizing, another LED industry within the industry event.

The forum, many senior LED industry experts will make a brilliant expert report. April 11, 2013 morning, general manager of China Semiconductor Technology Co., Ltd., Mr. Zhang Guoyi, will be in the forum for the development trend of nitride semiconductor substrate material report.

Zhang Guoyi, Ph.D., Professor of Peking University School of physics, semiconductor optoelectronics doctoral tutor, director of the joint research center of Peking University wide bandgap semiconductor, executive vice president of the Peking University Dongguan Academy of Opto electronics. Director of Institute of physics of light China Institute; Chinese Institute of Electronics optoelectronics information branch director, member of Specialized Committee China Semiconductor Physics Institute, member of China optical association LED Industry Association Advisory Committee; member of the expert group is the national semiconductor lighting alliance; is the "semiconductor journal" Journal "," light ", and the liquid crystal display board" the.

The substrate material determines the direction of technology development and extension, chip, packaging applications, different substrates and different technological requirements, different results are obtained, therefore, the development of substrate technology not only affects the development of the whole industry and technology, or the third generation semiconductor core technology, is the focus of international competition. This report describes the development trend of nitride semiconductor substrate technology, with a focus on the development trend of GaN single crystal substrate, patterned substrate and Si substrate.

GaN is a direct band gap material whose optical transition probability is an order of magnitude higher than that of the indirect band gap. Therefore, the GaN in the wide band gap semiconductor in short wavelength light-emitting diode, laser and UV detector, and high temperature microelectronic devices show a broad application prospect, is very suitable for the environmental protection material system.

Graphical substrate technology (Pattemed Sapphire Substrate), referred to as "PSS"". The microstructure of the LED substrate is fabricated on the surface of the sapphire LED substrate, and then the surface of the patterned substrate is extended. Sapphire LED substrate after PPS processing, it will improve the defects of sapphire LED substrate, the LED can be effectively improved by the epitaxial chip packaging can improve the efficiency of light extraction.

Silicon has a diamond structure with Fd3m space group, which belongs to cubic system. The body along the diagonal direction displacement 1/4 diagonal distance of two sets of fcc lattice nested into prescription. Silicon substrate is the current market price of the cheapest, can obtain the largest size, more mature semiconductor device technology.

What is the development trend of nitride semiconductor substrate technology, the market for the substrate technology and what kind of requirements of the times, in this report, will have a more detailed exposition. The forum covers the hot technology, LED whole industry chain innovation application, the relevant standards and policies, including: packaging, materials, OLED development, LED lighting, large domestic equipment, semiconductor lighting, energy-saving standard training project bidding etc.. At the same time also added a new release link, while brainstorming to understand the industry dynamics. China LED exhibition held at the same time, is China's electronic information Expo's professional exhibition, sponsored by the China semiconductor lighting /LED industry and application alliance, China electronics equipment corporation. In order to healthy development, win-win cooperation as the theme, 100 thousand square meters large platform, is expected to participate in the 2000 companies, the industry's 90000 mature buyers! The exhibition will focus on demonstrating the national LED industry excellent enterprise lineup, strength and level, make full use of the country (territory) and a variety of resources, and strive to build LED and semiconductor lighting industry pilot exhibition.

2013 China LED industry healthy development forum guests lineup, is poised to take off.
