Anji Microelectronics Technology Co., Ltd. (688019.SS): How It Works

• CMP (chemical mechanical planarization) slurries - tailored formulations for dielectric, oxide, and metal polishing steps.
• Photoresist strippers and developers - high-selectivity chemistries for patterning and removal with minimal substrate damage.
• Specialty etchants, cleaning agents and surface treatment chemicals for advanced packaging and heterogeneous integration.

• Multi-stage purification trains (filtration, distillation, membrane separations) to achieve semiconductor-grade impurity ceilings (ppb-ppt targets for metals and ionic species).
• Batch and continuous formulation lines with real-time analytical QA (ICP-MS, TOC, particle counters) to ensure lot-to-lot consistency.
• Cleanroom filling and packaging to prevent particulate and ionic contamination prior to shipment to fabs and OSATs.

• Product sales: direct sale of CMP slurries, strippers, cleaners, etchants and related consumables to IDM/foundries, OSATs and advanced packaging houses.
• Customized formulations and technical support contracts for yield optimization and process integration.
• After-sales services and recurring supply agreements that create stable, repeat purchase revenue streams tied to fab throughput.

• Domestic foundries, IDMs and advanced packaging companies in China forming the principal customer base; increasing exports to APAC and global players for select high-value products.
• Strategic role in import substitution: supplying domestically-developed alternatives to previously imported process chemistries, aligning with national semiconductor self-sufficiency objectives.

• Deep formulation and purification expertise enabling high-margin, differentiated chemistries that are difficult to replicate without significant R&D and process-control investments.
• Capital-light relative to fabs - primary investment in laboratories, pilot lines and quality systems rather than giant capex for wafer fabs, allowing faster scaling of revenue with smaller asset base.
• High recurring revenue characteristics: consumables consumed per unit of wafer/packaging throughput, providing predictable demand tied to customer production ramps.

• Import substitution and localization initiatives to reduce reliance on foreign specialty chemicals suppliers and capture domestic market share.
• Diversification of raw-material sourcing and vertical collaboration with upstream chemical suppliers to secure critical inputs and stabilize margins.
• Investment in R&D and pilot production to support next-generation nodes and advanced packaging chemistries demanded by customers.
