November 25, 2013 Engineering and LED Lighting Fair 2013 held in conjunction with LED Engineering Conference-CTO concert in Guangzhou Poly World Trade Museum, the 5th Conference Room D opened the curtain, electronic Directors and Dr. Xiao Guowei chaired the General Manager meeting.
Council under the LED industry chain , the lower four special, which has two special midstream . Conference invited well-known in the LED industry chain enterprises CTO and industry executives to share the latest cutting-edge technology and to be guests on to discuss technology trends , and downstream .
November 25 afternoon, CTO Conference first day through special focus on high-tech group title "Chip and equipment and materials" were discussed. Product Director Shen Qu Huan first to "Sapphire Material promising" as the theme of a speech he believes will be the trend of large-size substrate.
Quhuan Shen noted that the large size of the substrate can produce more chips in each MOCVD , so the use of large-size sapphire substrate is one of the primary means to reduce the cost of LED chips . Due to the presence of LED chip edge invalid area, so the larger the diameter , the more apparent than with the number of chips in diameter than the advantages. " To six inches of the substrate , for example, 9 times the surface area of the substrate is 2 inches , the number of chips is 10.9 x 2 inches of the substrate ."
