Global Bump PR Stripper Market Strategic Research Report

Scope of the Report

The global Bump PR Stripper market size is predicted to grow from US$ 63.02 million in 2025 to US$ 116 million in 2032; it is expected to grow at a CAGR of 9.1% from 2026 to 2032.

Bumping PR (Photoresist) Stripper is a specialized chemical solution used in wafer bumping and advanced semiconductor packaging processes to remove thick photoresist layers and process residues after electroplating or metallization steps. In wafer bumping processes, photoresists are often much thicker than those used in conventional lithography (typically 30–100 μm or more). Bumping PR strippers are formulated to effectively dissolve or decompose these thick resist layers while simultaneously removing metal residues such as copper, tin, or solder plating byproducts. At the same time, the chemistry must be compatible with bump metals and under-bump metallurgy (UBM) to avoid corrosion or structural damage. In 2025, global Bump PR Stripper production reached approximately 1458.79 MT. Raw materials mainly include organic solvents, amine compounds, chelating agents, corrosion inhibitors, and surfactants. These chemicals are supplied by large specialty chemical companies such as BASF, Dow, Arkema, Mitsubishi Chemical, and Solvay.

Bumping PR stripper is a specialized wet chemical used in semiconductor manufacturing, particularly in wafer bumping and advanced packaging processes, to remove thick photoresist layers and related residues generated after electroplating or metallization steps. Compared with conventional photoresist removers, bumping PR strippers must provide strong stripping capability while maintaining compatibility with bump metals and under-bump metallurgy (UBM) to prevent corrosion or structural damage. In recent years, the rapid development of advanced packaging technologies, including wafer-level packaging (WLP), fan-out wafer-level packaging (FOWLP), 2.5D/3D integration, and chiplet architectures, has significantly increased the demand for thick photoresist removal chemicals. In wafer bumping processes such as copper pillar bumping, solder bumping, and micro-bump formation, bumping PR strippers play a critical role in ensuring process cleanliness and yield.
