Electronic Chemicals
In electronic chemicals, purity decides everything. The gap between ppb and ppm control determines whether a product is allowed into a fab at all. This sector covers photoresists and ancillaries, electronic specialty gases, wet chemicals and high-purity reagents, CMP materials, packaging and substrate materials, and display materials.

Sector overview
Demand is set by fab capex and process node. Global semiconductor-grade chemicals reached roughly USD 54.2 billion in 2025, with wafer fabrication accounting for 75.7% of demand. Advancing nodes raise chemical consumption per wafer — from a materials perspective, the more advanced the process, the higher the chemical value per die.
AI is the strongest variable this cycle. HBM and GPU cluster expansion materially increased chemical consumption per wafer, concentrated in lithography and etch. The sector has shifted from tracking the semiconductor cycle to being pulled by compute investment specifically.
Supply is highly concentrated and fragile. Over 70% of critical semiconductor materials originate from a limited set of regions, and electronic-grade gas prices rose more than 300% during past shortages. This structure makes both import substitution and supply redundancy policy goals, opening a window for new entrants with qualification capability.

Segments and key indicators
Shares come from different years and bases; use them for order of magnitude only.
| Segment | Main product families | Structural reference |
|---|---|---|
| Photoresist & ancillaries | g/i-line, KrF, ArF, EUV resists; sensitisers, anti-reflective coatings, developers | Photoresist market passed USD 9.2 bn in 2025; EUV and high-end KrF remain concentrated |
| Electronic specialty gases | Etch and deposition gases, dopants, excimer laser gases, high-purity carriers | 34.3% of semiconductor-grade chemicals (2025) |
| Wet chemicals & high-purity reagents | Ultra-pure acids, bases and solvents; cleaners, etchants, strippers | Largest share in the broad definition (~44.8%) |
| CMP materials | Slurries, pads, post-CMP cleaners | Multi-patterning at advanced nodes raises consumption per wafer |
| Packaging & substrate materials | Underfill, moulding compounds, thermal interface materials, substrate chemicals | Heterogeneous-integration materials growing ~12% |
| Display materials | OLED emitters, liquid crystals, polarisers, wet chemicals | OLED emitter CAGR around 15% over five years |
Main participants
The top tier is fewer than ten global players holding core patents and high-end products with over 50% combined share. Chinese suppliers concentrate in mid- and low-tier specialty gases and wet chemicals, qualifying upward into high-purity grades.
| Company | Positioning |
|---|---|
| BASF / Linde / Air Products | Electronic specialty gases and process chemicals |
| JSR / 东京应化 (TOK) / 信越化学 | Leaders in high-end photoresists |
| 住友化学 / 三菱化学 | Display materials and high-purity chemicals |
| 安集科技 | CMP slurries; leading domestic substitution progress |
| 华特气体 / 南大光电 | Specialty gases and photoresist ancillaries |
| 雅克科技 | Precursors and platform electronic materials |
Key trends
These judgements are compiled from public sources and indicate direction rather than precise forecasts.
HBM and GPU cluster expansion was the primary driver of higher chemical consumption in 2025. HBM's stacking layers and bonding steps add cleaning, deposition and CMP chemical volume compared with conventional logic.
Multi-patterning at sub-3nm substantially increases steps, raising lithography and etch chemical volume. For suppliers this means material revenue can grow even on flat wafer shipments.
PFAS restrictions in Europe and the US affect several semiconductor process chemicals, with compliant alternatives costing 15%–20% more. Few categories see regulation directly gate process feasibility this way.
Domestic share in specialty gases and wet chemicals is rising, but the barrier in high-purity grades is fab qualification cycles rather than capacity. Qualification success, not capex, decides whether substitution converts.
