Recently, Sanzhuan Technology (Nanjing) Co., Ltd. (“Sanzhuan Technology”), an enterprise invested by Nanjing Venture Capital Group, rolled off its first domestically produced vertical-flow arsenic-phosphorus MOCVD system, marking a new milestone in the R&D of arsenic-phosphide compound semiconductors.
Founded in March 2024, Sanzhuan Technology’s team comprises several PhDs from the Chinese Academy of Sciences, engineers from leading semiconductor enterprises, and senior industry marketing professionals. The company focuses on semiconductor equipment manufacturing and is committed to overcoming key technical challenges in Metal-Organic Chemical Vapor Deposition (MOCVD) equipment. As core equipment in semiconductor manufacturing, MOCVD systems use high-precision thin-film deposition technology to grow high-quality compound semiconductor materials on substrates.
As core materials for strategic emerging industries, arsenic-phosphide compound semiconductors are widely used in critical fields such as commercial aerospace, optical communication, wireless communication, and new-type displays:
GaAs multi-junction solar cells provide efficient power supply for low-orbit satellites;
GaAs/InP laser chips support optical interconnection in AI data centers and automotive LiDAR operation;
RF devices based on HBT/pHEMT technology empower high-end communication systems;
Mini LED light sources drive the upgrading of the display industry.
In July 2025, Nanjing Venture Capital Group, together with Nanjing Qilin Venture Capital, invested tens of millions of yuan in Sanzhuan Technology. Aligning with Nanjing’s 1026 Advanced Manufacturing Cluster, Nanjing Venture Capital Group has precisely targeted semiconductor equipment, a key link in the industrial chain, and provided equity investment to Sanzhuan Technology at the seed stage, establishing a positive cycle of “capital injection – technology iteration – industrial upgrading”.
