"As we all know, MOCVD has a wide range of applications, including lighting, display, military, satellite, graphene, etc., which also highlights the importance of MOCVD in the entire compound semiconductor industry." Zhongyi Optoelectronics Chairman / CEO Chen Aihua is high The LED LED annual meeting said.
Chairman and CEO of Zhonghao Optoelectronics Chen Aihua
From December 21st to 22nd, 2017, the 2017 High-tech LED Annual Meeting and Golden Globe Awards Ceremony hosted by Gaogong LED was held at the Baoding Dunxi Road in Shenzhen Baoan. The big hotel opened.
As the annual year-end event of the LED industry chain, the 2017 High-Tech LED Annual Meeting will once again bring together the LED LED industry leaders, and the on-site 400+ industry elites will fully look forward to the LED industry landscape, market, capital, technology trends and trends, deep integration and Excavate new opportunities and strategies under the current industrial situation, and jointly solve the "decisive victory" of industry and enterprises.
On the afternoon of December 21, at the opening ceremony of “Industry Opportunities and Corporate Strategies Focusing on the Chinese Marketâ€, which was named by Jingyuan Optoelectronics, Chen Aihua delivered a keynote speech entitled “The Status and Development Trend of MOCVD Localizationâ€.
MOCVD equipment can support various layers in the LED structure, including light-emitting layer, reflective layer, electrode layer, etc. MOCVD equipment plays a key role in the application, because it determines the performance of the chip product and determines its cost.
Compared to the LED structure, MOCVD is relatively simple in electronic functional devices, but it also requires three layers, such as an isolation layer of aluminum oxide, a layer of gallium nitride, and a final electron growth layer. In general, MOCVD equipment is much more complicated in compound semiconductors, and the process is also highly dependent on equipment.
Indeed, the price of MOCVD has been reduced by 60% compared to the original. It is precisely because of the emergence of domestic equipment, MOCVD presents a large price reduction.
Nowadays, in the blue, white and green markets, after years of changes in the competitive landscape, only two foreign equipment manufacturers in Germany and the United States have monopolized. At present, because Germany cannot meet the needs of mass production, it has already been eliminated. There is a US left. Today, there are also two domestic real mass productions, Zhonghao Optoelectronics and Zhongwei.
In Chen Aihua's view, "domestic equipment has been verified by the scale of production of two generations of products, and it has already achieved cost competitiveness. The performance is also very close to that of American equipment factories. Some even exceed them, and the price is still cheaper."
Dr. Chen Aihua introduced that Zhonghao Optoelectronics has established its own intellectual property system and core technology system since its establishment. At present, it has established independent intellectual property rights in key technologies such as pallets and automated loading and unloading. Chen Aihua said frankly, "It is precisely because of the establishment of these intellectual property rights that we have differentiated competitiveness of our products. It can be said that China's independent intellectual property rights will not infringe domestic and foreign patents and intellectual property rights."
In addition, Zhonghao Optoelectronics established two principles at the time of its establishment, one is institutional innovation and the other is technological route innovation. Among them, the determination of the technical route must be market-oriented, not technology-oriented and product-oriented. In fact, both technology-oriented and product-oriented are market-oriented.
"Independent innovation can not be achieved in a day or two. It takes at least 5 years. We have already done two generations. The first generation of products is really not perfect. It has been improved in the second generation. Innovative products are the introduction of technology, which is very dependent on equipment. In addition, adhering to independent innovation, there must be a lot of capital investment, and the pressure to bear losses, this is absolutely." Chen Aihua said.
At present, the two generations of Zhonghao Optoelectronics have passed the verification, and both Sanan Optoelectronics and Huacan Optoelectronics have been put into production. In 2018, Zhonghao Optoelectronics will continue to enter the stage of mass production.
Written at the end
In fact, the market development has determined two points as early as 2011. The first MOCVD equipment can meet the needs of large-scale production. The second is that the cost must be low, the cost cannot be reduced, and the industry cannot develop.
After 7 years of accumulation and verification, Zhonghao Optoelectronics has established its core technology system of self-innovation equipment MOCVD. The third independent innovation must be used to bear the cost and will inevitably be harvested. Finally, the bottleneck of the epitaxial equipment of the third-generation semiconductor materials is being broken, and the domestic MOCVD has the potential to realize the transition from follow-up to overtaking.
What is a data cable
A data cable is used in establishing connections between multiple computers over a network. To use this, an ethernet cable is utilized. The ethernet cable uses the network interface to connected PCs.We have several kinds of data cables: USB Cable ,Micro cable,Cable for apple, HDMI Cable ,Displayport Cable,Thunderbolt Product and so on.
Usb Data Transfer Cable,Best Data Cable for Fast Charging,Best Hdmi Cable,Docking Station for Laptop,Mini Power Bank
