Domestic Photoresist Leader — Building a Platform in Electronic Chemicals

Research-style note (English) — company commonly associated with Tongcheng Advanced Materials and its photoresist / electronic chemicals ecosystem.

Company & History

Tongcheng has evolved from a specialty chemicals trader into an integrated electronic materials platform spanning photoresist, resin, and semiconductor-grade reagents, with fabs and R&D in China and overseas service hubs.

Milestones

1999 -> Tongcheng Chemical Co., Ltd. established\n2008 -> Tongcheng Group Co., Ltd. established\n2018 -> Listed on the Shanghai Stock Exchange\n2020 -> Acquired Beijing Kehua Microelectronics and Beixu Electronics\n2021 -> Fully acquired Hansen Resin (Zhenjiang)\n2022 -> Took a controlling stake in Beixu Electronics\n2023 -> Shanghai Tongcheng Electronics commenced production\n2024 -> Established Tongcheng Electronics' Changzhou plant\n2025 -> Established RA Thailand and RA Germany

Business Overview

Photoresist & lithography materials

• G-line / I-line, KrF, ArF photoresists for mature and advanced nodes; roadmap toward EUV and ancillary layers where feasible.
• Resin, PAG, solvent and formulation capability — critical to supply security and margin.
• Serves logic, memory, CIS, power fabs; qualification cycles are long but create sticky revenue once approved.

Platform strategy

• Semiconductor photoresist as the core anchor
• Expand to wet chemicals, CMP slurries (where applicable), packaging materials — cross-selling to the same fab customers
• Domestic substitution: benefits from fab localization and supply-chain resilience policies in China

Competitive Advantages

1. Full-stack formulation + key raw materials (resin / additives) reducing import dependence
2. Fab qualifications — asset-light vs. greenfield but high barriers once in the BOM
3. Global footprint — Thailand / Germany entities support overseas customers and risk diversification
4. M&A integration — Kehua, Beixu, Hansen examples of extending technology and customer reach

Industry Context

• Wafer fab capacity additions in China and SE Asia sustain baseline photoresist demand.
• Advanced nodes (ArF immersion, upcoming EUV layers) concentrate share among a handful of global suppliers; domestic leaders focus on catching up in ArF and niche EUV auxiliary layers while winning share in 8″ / mature 12″ nodes first.
• Pricing is influenced by raw materials, yen / FX, and competitive licensing dynamics.

Risks

1. Technology risk: Slower-than-expected qualification at leading-edge nodes
2. Capex / fab utilization: If semiconductor cycle weakens, volume and pricing pressure on materials
3. Raw material & IP: Dependence on specialty monomers and patents; litigation or export restrictions
4. Integration: Cross-border M&A execution and synergy realization

Summary

The company is positioned as a domestic photoresist and electronic chemicals platform, combining internal capacity, strategic M&A, and global service nodes to capture import substitution and fab expansion — with the main upside tied to qualification progress, mix shift to ArF/higher-value products, and steady fab utilization across the cycle.
