【Member News】Setting the Standard for the Future! Two Gallium Oxide Group Standards Led by Garen Semiconductor Officially Released

      Recently, two group standards led by Hangzhou Garen Semiconductor Co., Ltd.—β- Gallium Oxide Homoepitaxial Wafers (T/CEMIA 050-2025) and Test Method for Dislocation Density in Gallium Oxide Single Crystals (T/CEMIA 051-2025)—were officially approved and released by the China Electronic Materials Industry Association. Both standards will come into full effect on January 1, 2026.

      This marks a major breakthrough in China’s standardization efforts for fourth-generation semiconductor materials, signaling a critical step forward for the Gallium Oxide industry from technological research toward large-scale industrial application.

      The leading organization for β-Ga₂O₃ Homoepitaxial Wafers (T/CEMIA 050-2025) is Hangzhou Garen Semiconductor Co., Ltd.

      Other participating organizations include: the 46th Research Institute of China Electronics Technology Group Corporation (CETC), University of Science and Technology of China, the 13th Research Institute of CETC, Xidian University, Nanjing University, Sun Yat-sen University, Yongjiang Laboratory, Zhejiang University, Zhejiang University Hangzhou International Science and Technology Innovation Center, Hangzhou Fujia Gallium Technology Co., Ltd., Evolution Semiconductor Co., Ltd., Shenzhen Pinghu Laboratory, China Resources Microelectronics Limited, NEXTGO EPI UG, University of Electronic Science and Technology of China, Anhui University, Xiamen University, Suzhou Institute of Nano-Tech and Nano-Bionics (SINANO), Chinese Academy of Sciences, GaFuture Semiconductor Technology (Jinjiang) Co., Ltd., Dalian University of Technology, Dongguan Institute of Materials Science and Technology, Chinese Academy of Sciences, Hubei Jiufengshan Laboratory, Hangzhou Xinchuangde Semiconductor Co., Ltd., Southwest University, and The Hong Kong University of Science and Technology.

      The leading organization for Test Method for Dislocation Density in Gallium Oxide Single Crystals (T/CEMIA 051-2025) is also Hangzhou Garen Semiconductor Co., Ltd.

      The other participating organizations are the same as those involved in T/CEMIA 050-2025, including major research institutes, universities, laboratories, and industrial partners across China and abroad.

      These two Gallium Oxide–related group standards, released by the China Electronic Materials Industry Association, will provide authoritative references for quality control of β-phase Gallium Oxide homoepitaxial wafers and for unified testing of dislocation density in Gallium Oxide single crystals. The implementation of these standards will accelerate the transition of Gallium Oxide from laboratory research to large-scale production, laying a solid foundation for China to establish both technological and industrial advantages in the field of ultra-wide-bandgap semiconductors. This progress will help unlock the industrial value of Gallium Oxide as the “king of ultra-wide-bandgap semiconductors” and support national strategies in new energy and high-end manufacturing.
