About Mingjia Semiconductor

Mingjia Semiconductor, established in November 2020, specializes in the research, development, and production of fourth-generation semiconductor materials. The company's legal representative and founder is Chen Zhengwei, who holds a doctorate from Saga University in Japan where his research focused on gallium oxide materials. The core team includes PhDs from institutions like the University of Tokyo and Tsinghua University, alongside industry veterans from companies such as SMIC and Lucent Technologies. The firm focuses on producing ultra-wide bandgap semiconductor gallium oxide (Ga2O3), indium phosphide (InP) crystals, and large-sized doped optical crystals. Gallium oxide is noted for its high breakdown voltage and efficiency, making it suitable for high-power and high-frequency applications at a lower cost than silicon carbide. The company has developed a complete industrial line for gallium oxide, encompassing crystal growth, processing, film epitaxy, and performance testing. Mingjia Semiconductor has achieved mass production of 4-inch gallium oxide wafers and has successfully developed 4-inch (001) single crystal substrates. Mingjia's products serve a wide range of high-tech sectors, including new energy vehicles, industrial motors, 5G communications, aerospace, and smart grids. The company supplies its materials and provides technical services to a global client base, which includes major corporations like Huawei and BYD. By 2023, its annual revenue exceeded 100 million yuan. The company has completed multiple funding rounds from investors such as Hongtai Fund, Inno Angel Fund, and Share Capital.
