Project Brief introduction: Aiming at the bottleneck of Gallium Oxide ultra-wide band gap power semiconductors, Xianlin Semiconductor team of Nanjing University has developed core technologies such as mass production heteroepitaxy integration, electric field management, avalanche energy dissipation and advanced packaging, overcome the problem of material and device "jam", and proposed and realized the "China solution" of energy-efficient Gallium Oxide power devices. The new generation of power electronic devices for complex electrical environment applications, the comprehensive performance is better than the existing wide band gap semiconductor power devices, has been initially applied to photovoltaic inverter power modules, and effectively promote the technological change and practical process in the field of power electronics.

National Sun Yat-sen University joins hands with Taiwan Applied Crystals to jointly develop Gallium Oxide single crystal bulk

      With the rapid development of science and technology, new semiconductor materials are constantly introduced. As a new generation of compound semiconductor materials, Gallium Oxide (Ga₂O₃) shows great application potential in electric vehicles, aerospace, communications and energy. However, its single crystal bulk production technology has become a key bottleneck in the development of the industry.

      In order to solve this problem, National Sun Yat-sen University has worked closely with Taiwan Applied Crystal Co., Ltd. and its affiliated groups to develop large-size Gallium Oxide crystal growth technology.

      After careful planning, the two sides signed a project cooperation contract, the company will provide 50 million Taiwan dollars of financial support, the goal is to achieve a 6-inch Gallium Oxide single crystal block mass production within 3 years.

      Sun Yat-sen University has deep technical accumulation in the field of wide band gap semiconductor materials. The Crystal Research Center led by Professor Mingqi Zhou of the university has taken the lead in the research and development of Gallium Oxide epitaxial thin films domestic and international. And has successfully grown silicon carbide crystal bulk with a diameter of 6 inches. This technological breakthrough laid the foundation for the growth of Gallium Oxide single crystal bulk.

      In order to achieve the goal of producing 6 inches of Gallium Oxide single crystal bulk within 3 years, Sun Yat-sen University not only designed the crystal growth equipment, but also incubated the related manufacturing enterprises. At present, four 6-inch silicon carbide long crystal furnaces and one 8-inch silicon carbide long crystal furnaces have been put into use, laying a solid foundation for future research on Gallium Oxide.

      The cooperation will further promote the deep integration of academia and industry and inject new vitality into the semiconductor industry in Taiwan, China. With the continuous breakthrough of technology and the growth of market demand, Gallium Oxide single crystal bulk are expected to become an important competitive field in the future semiconductor market.
