Chairman Zong revealed in the program "Hard Science and Hard Shell" that "the company's 8-inch substrates have fully reached the quality standards of 6-inch substrates and have been supplied in batches. Downstream device manufacturers can boldly switch to 8-inch substrates." I would like to ask two questions: 1) Does the company's mass-produced 8-inch substrates adopt the physical method or the liquid method? 2) Is the 8-inch substrate produced by the production line of the Jinan factory or the Shanghai Pudong factory?

Tianyue Advanced: Dear investors, hello! The company is one of the earliest companies in China to engage in the research and development and industrialization of 8-inch products. At present, the industry still mainly uses the PVT method (physical vapor transport method) to prepare 8-inch substrates. The company has achieved mass production and will arrange capacity expansion plans based on downstream customer needs and industry development. At the 2023 Semicon Forum, the company's Chief Technology Officer Dr. Gao Chao also reported on the company's core technology and forward-looking research and development. The company prepared 8-inch crystals with low defect density through the liquid phase method, which is an industry first. At present, the company's products are mainly conductive silicon carbide substrates. The Shanghai Lingang factory began product delivery in May 2023. At present, the Jinan factory and the Shanghai Lingang factory both have a certain production capacity of 8-inch products. Thank you for your attention!
