EU Proposes Export Pre-Licensing for EUV Lithography辅助Chemicals
Photoresist suppliers face stricter regulation; high-end chip manufacturing supply chain faces new geopolitical pressure.
Brussels — The EU Trade Commission this week proposed listing EUV lithography auxiliary chemicals—including high-purity photoresists and anti-reflective coatings—on the export pre-licensing list, in what is seen as a response to chip supply chain security concerns.
Proposal Details
Under the proposal, exports of chemicals with the following characteristics will require advance approval:
- Photoresist purity above 99.999%
- Anti-reflective coating refractive index adjustable range exceeding 1.8-2.4
- Developers specifically designed for 3nm and below processes
Approval cycle is expected to be 45-60 working days.
Industry Reactions
Chip manufacturers worry the approval cycle will affect urgent order delivery capacity. One Asian wafer fab executive said: "We're used to next-day supply chain response. A 45-day approval cycle is a nightmare."
Chemical suppliers have mixed attitudes: large suppliers believe compliance costs can be passed to customers; small and medium suppliers are concerned about complex approval procedures potentially forcing them out of the high-end market.
Market Impact
Following the announcement, high-purity photoresist futures prices rose 12% in a single day, with some investors expecting supply tightness to persist.
Analysts note that if the proposal passes, it may prompt more chip manufacturers to accelerate inventory strategy adjustments, or even drive regionalized supply chain construction.
