Hello, Secretary Dong. I read an article today and learned that the liquid phase SiC substrate preparation method has obvious cost advantages compared to the PVT method SiC substrate preparation method. I wonder if the company has conducted research on the liquid phase method. If so, does it have a small or pilot production line? In addition, the fourth-generation semiconductor materials restricted for export by the United States are also one of Professor Xu Xiangang's research directions. Does the company have any industrial cooperation with Shandong University on the fourth-generation semico

Tianyue Advanced: Dear investors, hello! Silicon carbide substrate preparation technologies include PVT (physical vapor transport), solution method and high-temperature vapor phase chemical deposition method. At present, the industry mainly uses PVT method for the growth of silicon carbide single crystals. The company has been deeply engaged in the field of silicon carbide substrates for more than ten years and has always been at the forefront of technological development. "Liquid phase silicon carbide single crystal preparation technology" is one of the related technologies that the company has deployed earlier. The company always adheres to "hard technology", closely follows the development trends of industry technology, insists on R&D and innovation as the vitality of the company's long-term development, seizes the development opportunities of the semiconductor industry, continues to consolidate its own operating capabilities, strives to expand profit growth points, and continuously strives to enhance the company's value. I admire and thank you for your in-depth understanding of the industry, your attention and support to the company, and wish you a happy life!
