Our R&D Team

Annsemic has always insisted on building a competitive R&D and innovation team in China. Now, we have a very rich experienced R&D team on epitaxy, chip, package and module development and they are with young age, strong ambition, and powerful strength. There are more than 20 technical personnel, 50% of them have a master’s degree or above, and all of them have a bachelor’s degree or above. Among them, 5 years of industry experience accounted for 70%, and 3 years of industry experience accounted for 100%.

And we have a complete design, production, technology and control system, and can independently complete customized tasks including epitaxy, chips, package and modules. We combines production, education and research, and conducts technical cooperation with domestic well-known universities such as “Peking University, University of Science and Technology of China, Ningbo Institute of Materials, Chinese Academy of Sciences” and other well-known domestic universities in multiple forms, multiple methods, and multiple channels.


Current main research direction: 

  • Research on high-power UVC-LED epitaxy & chip technology;
  • Research on high Al composition AlGaN PN ohmic contact;



  1. Developed the technology of NPSS side extension in small closing area
  2. Developed a high-mobility N-AlGaN growth technology
  3. Developed a quantum well growth process that achieves high internal quantum efficiency
  4. Developed thin-layer epitaxy control method
  5. Developed sapphire back and side roughening technology
  6. Developed OHMIC contact technology of high Al composition AlGaN
  7. Developed 6L/min flowing water sterilization module

Let's Work Together!

Whether it is ordering a UVC sample to take your design to the next step or planning to start a new UVC project this is where to get connected with what you need.
