What is the position of the company's third-generation semiconductors in China? What is its production capacity and technology ranking? What are its outstanding advantages and current production capacity? With the rise of new energy and photovoltaics, what is the company's layout? Is there any growth in the current production capacity and shipment rate of minled?

Sanan Optoelectronics: Hunan Sanan, a wholly-owned subsidiary of the company, is mainly engaged in the research and development and industrialization of third-generation compound semiconductors such as silicon carbide and silicon-based gallium nitride. The total investment is 16 billion yuan (including land use rights and working capital). After the project reaches full production, the supporting production capacity will be about 360,000 pieces/year. As of the end of June 2022, Hunan Sanan has reached a production capacity of 6,000 pieces/month. The company's silicon carbide substrates have been sent to many international manufacturers for verification, and have been verified by customers and sold. Silicon carbide diode products have covered PFC power supplies, on-board chargers, photovoltaic inverters, home appliances and other application fields. Major customers include a well-known domestic customer, Weimaisi, Fudi Power (BYD), Sungrow Power Supply, Growatt, GoodWe, Sineng, Deye, Vertiv, Bit, Great Wall, Infineon, Kehua, Invt, Gree and other customers; Silicon carbide MOSFET products have been sent to dozens of customers for verification, and the foundry business has cooperated with leading new energy vehicle supporting enterprises; the cooperation between automotive-grade products and key new energy vehicle customers has made major breakthroughs, and the depth and breadth of business cooperation intentions are constantly extending. In terms of silicon-based gallium nitride, the process of customer engineering sample delivery and system verification of products is accelerating. At present, the company's share of high-end LED fields continues to increase, especially the application of MiniLED has been continuously promoted by international leading customers, among which the shipments of a single customer have grown steadily; the shipments of another customer have increased since April, and the sales scale has climbed month by month; domestic customers have entered small-scale production of MiniLED backlight solutions for TVs and notebooks, and RGB direct display large screens are expected to be launched on the market before the end of the year.
