According to the Qilu Evening News, the first batch of overseas high-level talents in Qingdao, the winner of the Million Venture Fund, returned to China Dr. Zhuang Dejin has been developing nitride semiconductor substrate wafers in Qingdao for three years. Nowadays, the first batch of crystals developed by Zhuang Dejin team has been introduced to the market, which is expected to replace the existing sapphire substrates in the field of LED lighting, change the LED industry chain, and accelerate the popularization of LED lighting to ordinary households.
“The growth of this substrate wafer developed by our team is twice as large as that of the US company. The performance is even better and the cost is reduced by half.†On the afternoon of the 15th, at Qingdao Aluminum Gallium Opto Semiconductors Co., Ltd. in Laoshan District, Zhuang Dejin introduced the nitride semiconductor substrate wafers they developed.
Nitride wafer is the source of LED optoelectronic semiconductor industry chain. It is the substrate material for LED epitaxial wafer preparation. The device made on the basis of this semiconductor substrate wafer can be applied to high temperature and high frequency, automobile engine, drilling bit and so on. In the high-temperature field, LED lighting products will be more than doubled in luminous efficiency compared to current aluminum oxide substrates.
According to reports, GaN substrate wafers have the advantages of low cost and high cost performance, which can drive the downstream industry to adjust the technical structure and improve production efficiency. “For example, in the past, a total of 15 steps were required to produce an LED product. After using a GaN substrate wafer, the production process only took six or seven steps.†Zhuang Dejin said that after the GaN substrate wafer was introduced to the market, It is expected to replace the existing sapphire and other substrate materials in the high-end field, and truly change the LED industrial chain, and will promote the popularity of LED lighting to ordinary households to a certain extent, and further achieve the effect of energy saving and environmental protection.
Today, the Zhuang Dejin team has cooperated with several well-known domestic enterprises and research institutes such as the Institute of Physics of the Chinese Academy of Sciences. "The production capacity is limited now, and many large orders are not dare to pick up." Zhuang Dejin said that the GaN substrate wafer was just introduced to the market last year. As the market demand continues to expand, Zhuang Dejin will lead his project team to Qingdao. The Wanping Rice Incubator will further expand the production scale, and the existing production capacity will be greatly improved by then.
