Global CMP Slurry Diluent Market Strategic Research Report

Scope of the Report

The global CMP Slurry Diluent market size is predicted to grow from US$ 607 million in 2025 to US$ 1,153 million in 2032; it is expected to grow at a CAGR of 9.6% from 2026 to 2032.

A slurry diluent is an auxiliary liquid used in chemical mechanical polishing (CMP) processes. Its primary function is to dilute high-concentration polishing slurry to the desired concentration according to process requirements, thereby controlling the polishing rate, improving surface uniformity, and minimizing damage to the polishing pad and wafer. It is typically composed of deionized or purified water, buffers, and functional additives, with formulations adjustable for different materials and process conditions.In 2025, global CMP slurry and slurry diluent production reached approximately 414 M liters, with an average global market price of around US$1.5 per liter. Annual production capacity is 480 M liters. Gross Profit Margin: ≈28%.CMP slurry and slurry diluents occupy a critical position in the semiconductor manufacturing ecosystem. The upstream segment includes raw materials suppliers such as high-purity abrasives (silica, alumina), chemical additives, and ultra-pure water systems. Midstream is dominated by CMP slurry manufacturers, who formulate, mix, and package specialty slurries and diluents tailored to specific wafer processes. Downstream, semiconductor fabs, LED fabs, and advanced optics producers are the primary consumers, relying on high-quality slurry and diluents to ensure wafer planarization, device yield, and production stability. The industry is tightly linked, with technology and purity requirements forming high entry barriers.CMP slurry and its diluents are strategic consumables that directly influence semiconductor manufacturing efficiency and yield. With the continued push toward advanced nodes and more CMP steps per wafer, demand for both standard and customized slurry solutions will grow steadily. Investing in suppliers who offer high-purity, consistent, and technically supported slurry and diluents can provide a competitive edge to fabs. Moreover, innovation in slurry formulations, such as low-damage or eco-friendly variants, is likely to become a key differentiator in the next 5–10 years.
