Hello, Secretary Dong! Your company's conductive silicon carbide devices are far inferior to gallium germanium devices in terms of production capacity, revenue and profit contribution. What is the reason? Will your company increase its R&D investment in silicon carbide devices in the future?

Tianyue Advanced: Dear investors, hello! Tianyue Advanced is a leading domestic wide bandgap semiconductor (third generation semiconductor) substrate material manufacturer, mainly engaged in the research and development, production and sales of silicon carbide substrates. Its products can be widely used in microwave electronics, power electronics and other fields. With its outstanding R&D and innovation capabilities, the company has become one of the few silicon carbide substrate manufacturers in the world that has mastered semi-insulating and conductive silicon carbide substrates and has a relatively complete product size. The company has always adhered to the business philosophy of "advanced quality and continuity". In recent years, it has continued to increase its R&D investment. On the one hand, it has continued to increase its R&D investment related to the large-scale industrialization of conductive substrates to lay the foundation for the commissioning of the Shanghai Lingang project; on the other hand, the company continues to strengthen the R&D and technology iteration of large-size high-performance indicator products, and continues to maintain its leading competitive advantage. At this stage, the company is accelerating the market development and capacity construction of 6-inch conductive substrates. This time, the company has signed a long-term agreement with customers with an estimated amount of 1.393 billion yuan, which provides a strong guarantee for the company's sales of 6-inch conductive silicon carbide substrates and has a large industry and market influence. The company's strategy has always been to focus on silicon carbide substrates. It is not easy to make substrates well and finely, and the market demand for substrates is large enough. The company will adhere to the focus strategy and strive to make substrates further well and finely, with larger sizes and fewer defects, to continue to meet the needs of the rapidly growing downstream application end. In the future, the company will always be customer-centric, continue to increase R&D investment, strengthen independent innovation, accelerate product iteration, improve product quality, increase production capacity, expand market share, and strive to become a leading company in the international wide bandgap semiconductor industry. Thank you for your attention and wish you a happy life!
