Global PHS Resin for KrF Photoresist Market Strategic Research Report

Scope of the Report

The global PHS Resin for KrF Photoresist market size is predicted to grow from US$ 216 million in 2025 to US$ 400 million in 2032; it is expected to grow at a CAGR of 9.3% from 2026 to 2032.

In 2024, global PHS resin for KrF photoresist production reached approximately 321 tons, with an average global market price of around US$ 575/kg. PHS resin (Polyhydroxystyrene resin or Poly(4-Vinylphenol)) is a phenolic polymer widely used as a base resin in KrF (Krypton Fluoride) photoresists, which are used in photolithography processes at 248 nm wavelength. The PHS resin provides excellent film-forming properties, thermal stability, and compatibility with photoactive compounds (PAGs). It allows fine pattern resolution, etching resistance, and developer solubility critical for semiconductor manufacturing at deep-UV (DUV) wavelengths.

PHS Resin for KrF Photoresist can be divided into narrow distribution type and broad distribution type. Key indicators of PHS resin include molecular weight distribution (MWD), polydispersity index (PDI) and metal impurities. The demand for narrow distribution PHS resin is increasing because its uniform polymer chain length and tightly controlled molecular weight lead to more consistent dissolution rates, reduced line edge roughness, and higher resolution—critical for advanced KrF lithography nodes where pattern precision directly impacts yield. Additionally, as semiconductor makers push for tighter process windows and higher device performance, the superior film uniformity and reproducibility of narrow distribution types make them more attractive despite higher production costs.

KrF lithography remains critical for ≥90 nm nodes—especially in memory (including 3D NAND), automotive, microcontrollers, sensors, PMICs, and display driver ICs. Growing demand in Logic/MPU applications, propelled by trends like AI, 5G, and IoT, is now the fastest-growing sub-segment for KrF photoresist usage. This promotes the demand of PHS resin accordingly.

PHS Resin industry has high technology barrier and production mainly distributes in Japan, South Korea and China. Chinese suppliers are emerging ones, with more capacity will be released in the coming years. In addition, PHS resin manufacturers are able to provide customized PHS resin according to clients' specific requirements.
