[Text|High-tech LED reporter Gan Qin] "At the end of 2013, we successfully developed LED square substrate, which can improve the utilization rate of 30% in the MOCVD stage compared with the conventional substrate sheet, and has an advantage in cost." Guizhou Haotian Zhang Gonglei, director of engineering technology of Optoelectronics Technology Co., Ltd. (hereinafter referred to as “皓天光电â€), said, “In 2014, square substrates have been shipped in small quantities, and will achieve substantial growth in the next year.â€
Haotian Optoelectronics Co., Ltd. is the world's leading manufacturer of large-scale sapphire materials. The company can supply various types of materials such as sapphire crystals, bar stocks, cutting sheets, polishing sheets, etc., to meet the large size LED lining of 2 inches to 8 inches and above. At the same time as the demand for the bottom material, the customer's demand for sapphire windows, lenses, crystals and other materials is met.
Zhang Gonglei introduced that in the process of square substrate processing, there are mainly the following difficulties: crystal orientation control and positioning chamfer processing in crystal rod processing, BOW and LTV control during grinding and polishing, it is difficult to control particles during cleaning process In addition, in the process of processing, according to product requirements, design new fixtures to use.
"It is expected that in the near future, square substrates may replace conventional circular substrate sheets. The development of this technology is probably the first in China and abroad at present." Zhang Gonglei said, "through the company's continuous research and development, products Parameters such as Thickness, TTV, Warp, BOW, and LTV have reached and exceeded customer demand."
Zhang Gonglei introduced that Haotian Optoelectronics 2-inch LED square substrate has the following advantages: Thickness=430±10um; TTV<4um; Warp<8um; -6≤BOW≤0um; LTV<1.5um(8*8);CA +/-0.05; CM 0.2 +/- 0.05; cleaning particle size less than 50.
Known as the "LED industry Oscar" selection of the 2014 (fifth) high-tech Golden Globe Award - annual LED good product selection activity, Haotian Optoelectronics will participate in the "LED chip substrate material" with the above 2-inch square substrate "Class Golden Globe Awards.
At present, the 2014 (5th) High-tech Golden Globe Award - the annual LED good product selection has entered the WeChat voting stage: August 8 - September 30.
