- Business
- Jiangsu Aisen Semiconductor Material Co., Ltd. engages in the research, development, manufacturing, and sale of specialized electronic chemicals and advanced semiconductor materials. Founded in 2010 and headquartered in Kunshan, Jiangsu Province, China, the company operates across key segments within the integrated circuit fabrication, advanced semiconductor packaging, electronic display, printed circuit board (PCB), and photovoltaic industries. The company provides an extensive portfolio of high-purity process chemicals, organized into two core product lines: electroplating solutions and photoresist systems. Its electroplating products and supporting reagents include electroplating copper additives and electrolyte systems for dual-Damascene processes; ultra-high-purity cobalt sulfate solutions; high-speed and rack/barrel tin and tin-alloy plating chemistries; lead-free solderable coating solutions; degreasing, pickling, and micro-etching pretreatment formulations; and anti-oxidation and post-treatment rinsing agents applied across wafer-level bumping, redistribution layer (RDL), through-silicon via (TSV), lead frame packaging, passive electronic components, and high-density interconnect (HDI) PCBs. Its photoresist and auxiliary chemical portfolio comprises positive and negative photoresists; thick-film negative photoresists engineered for advanced packaging and glass substrate applications; OLED array photoresists; and photolithography wet chemicals including tetramethylammonium hydroxide (TMAH)-based developers, organic strippers, edge bead removers (EBR), and specialized rinsing agents. Jiangsu Aisen Semiconductor Material serves semiconductor foundries, outsourced semiconductor assembly and test (OSAT) providers, display manufacturers, and electronics producers across domestic and international markets, supplying customers such as Semiconductor Manufacturing International Corporation (SMIC), Hua Hong Semiconductor, JCET Group, Tongfu Microelectronics, Huatian Technology, ASE Group, BOE Technology Group, Visionox, and AT&S. In recent developments, the company completed its initial public offering on the Shanghai Stock Exchange Science and Technology Innovation Board (STAR Market) under ticker 688720 in December 2023. Expanding its international operational footprint, the company acquired an 80% equity interest in Malaysia-based Inofine Chemicals Sdn Bhd in late 2024 to strengthen its overseas chemical manufacturing and distribution network across Southeast Asia. In early 2025, the company announced the acquisition of a 70% controlling interest in Binuo (Suzhou) New Material Co., Ltd. to strategically expand into high-purity OLED intermediate and sublimation materials for major display manufacturers. Furthermore, the company has commercialized and scaled mass production for advanced packaging negative photoresists, glass substrate photolithography materials, and advanced-node Damascene plating additives for advanced packaging and sub-28-nanometer fabrication processes.
