Mr. Secretary, what is the progress of the company's 8-inch product development? What are the production and sales volumes of the 6-inch conductive silicon carbide substrates currently on sale? What is the planned production volume in the future?

Tianyue Advanced: Dear investors, hello! Substrate diameter is one of the important indicators to measure the level of crystal preparation, and it is also an important way to reduce the cost of downstream chip preparation. The silicon carbide substrate industry will inevitably develop in the direction of larger sizes in the future. The company is currently also developing 8-inch products and has achieved breakthrough results. According to information disclosure regulations, some R&D projects and progress are exempted from disclosure due to high confidentiality. At present, the production and sales volume of 6-inch conductive silicon carbide substrates will continue to increase. Before the Lingang factory project is put into mass production, the company does not have the production capacity arrangement for large-scale conductive substrate sales. As of now, the Shanghai Tianyue Silicon Carbide Semiconductor Materials Project located in Lingang, Shanghai has been successfully capped. The project will be mainly used to increase the production capacity of conductive substrates. The project is expected to achieve the first batch of mass production in the third quarter of 2022. After the Lingang project is fully put into production, the company will add about 300,000 pieces of silicon carbide substrates per year, which will add new momentum to the continued growth of revenue and the long-term development of the company. Please continue to pay attention to the subsequent disclosure of the production and sales situation after the project is put into production. Thank you for your attention!
