EU Commission approves €288m German Chips Act state aid for Carl Zeiss HNA@SCALE and Zadient SiC-Pro

Mechanism

The Commission cleared two distinct Article 107(3)(c) TFEU measures, both designated 'first-of-a-kind' under the European Chips Act's Pillar 1 framework, which authorises State aid for novel facilities that do not yet exist at industrial scale in the EU:

Carl Zeiss SMT — HNA@SCALE (€222m, Oberkochen, Baden-Württemberg) Carl Zeiss SMT GmbH is the world's sole supplier of extreme-ultraviolet (EUV) optical columns to ASML, the world's only EUV lithography OEM. The High-NA (High-Numerical-Aperture) EUV generation — with numerical aperture ≥0.55 vs. ≤0.33 for prior generation — is the enabling technology for below-2nm semiconductor node manufacturing at TSMC, Intel, and Samsung. The HNA@SCALE project industrialises Zeiss's production process for these columns at its Oberkochen campus, removing the primary manufacturing bottleneck in the global EUV supply chain. The €222m aid is notified as a direct grant under German federal-government authority.

Zadient Materials Europe — SiC-Pro (€66m, Bitterfeld, Saxony-Anhalt) Zadient Materials Europe GmbH (a joint venture between Zadient Technologies SAS — a Zeiss + Arkema-affiliated SiC materials startup — and German industrial partners) will construct an ultra-pure silicon carbide (SiC) source-material facility in the Bitterfeld chemical-industrial cluster. SiC wafers are the key substrate for EV power-inverter chips (replacing silicon for higher-efficiency power conversion), RF power devices, and high-voltage rail / industrial electronics. The feedstock supply chain for SiC is currently dominated by China (~80% of global SiC production). The SiC-Pro project is the first EU-funded intervention at the upstream SiC-source-material tier, one step further upstream than the filed Onsemi Czech SiC-wafer-fabrication facility (2025-11-21-eu-czechia-onsemi-state-aid-sic-fab).

Supply-chain tier context

This decision expands EU Chips Act state-aid coverage to the deepest upstream tiers of the semiconductor supply chain:

Downstream implications

• ASML capacity unlock: Zeiss's High-NA EUV optical column production is the binding constraint on ASML's High-NA EUV scanner output. HNA@SCALE directly increases ASML's addressable High-NA production capacity. The prior High-NA EUV scanner (TWINSCAN EXE:5000) had a list price of ~€350m; ramp throughput is currently limited by Zeiss optic manufacturing capacity.
• SiC supply-chain reshoring: Zadient SiC-Pro, combined with the Onsemi Olomouc fab, creates a potential EU-sourced end-to-end SiC supply chain (source material → wafer → chip), directly material to the EU's EV powertrain strategic-autonomy objectives and reducing dependence on Chinese SiC raw materials.
• Chips Act "first-of-a-kind" cohort now spans 7+ cleared decisions with cumulative public + private investment >EUR 31.5bn; IP/26/1095 adds a qualitatively new supply-chain-tier dimension beyond prior approvals that covered only chip-fab and chip-design.
• Germany Chips Act cohort: Together with prior cleared German measures (€5bn ESMC/TSMC Dresden; €623m two first-of-a-kind facilities IP/25/3020; €920m Infineon), the total German Chips Act state-aid portfolio now exceeds €7bn committed.

Open questions

• Zadient Technologies SAS's equity structure and final commercialisation pathway (Zeiss + Arkema co-shareholder disclosure pending)
• Timeline for Zadient SiC-Pro facility to reach production: Bitterfeld permits + construction schedule not yet disclosed
• Whether HNA@SCALE will be sufficient to accelerate ASML's High-NA EUV throughput ramp beyond the current ~10-20 tools/year constraint
• Whether the parallel German €1.3bn renewable-hydrogen state-aid clearance (IP/26/1096, same day) reflects coordinated BMWK package or separate notified measures
