Abstract: The ultra-wide band gap semiconductor material β-phase gallium oxide (β-Ga2O3), with its ultra-wide band gap (4.8~4.9 eV), high breakdown field strength (8 MV/cm) and excellent Baliga figure of merit (>3 000), has shown great application potential in high-voltage and high-power fields such as smart grids, new energy vehicles and rail transit. In recent years, the research on β-Ga2O3 has made breakthroughs in many technical fields, and its industrialization process is at a critical stage of transition from laboratory research and development to large-scale production. From the perspective of industrialization, this article systematically sorts out and summarizes the development trend of the whole industrial chain of β-Ga2O3, and provides an important reference for industry practitioners to accurately grasp the pace of industrialization of β-Ga2O3. Firstly, the mainstream technology path in the whole industrial chain of β-Ga2O3 is briefly introduced. Subsequently, the current industrial development status of β-Ga2O3 is elaborated in detail around the three core links of “single crystal-epitaxy-device”, and the challenges faced by β-Ga2O3 in p-type doping, thermal management, reliability verification and cost control are comprehensively analyzed, as well as the efforts of researchers to solve these problems. Finally, the potential applications of β-Ga2O3 power devices in the fields of new energy vehicles, photovoltaic inverters, data center power supplies and high voltage direct current transmission are deeply analyzed, and the future market development prospects are forecasted, in order to provide reference for the industrialization and coordinated development of β-Ga2O3 related fields.
