Yes—ASML’s XT:260 i-line tool is designed to work in conjunction with ArF and EUV systems, handling non-critical layers to reduce overall lithography costs. This hybrid strategy helps make ArF-EUV chips cheaper and more scalable, especially for advanced packaging and mainstream logic.
How XT:260 Complements ArF and EUV
ASML’s lithography strategy is built around a layered cost-performance model:
- EUV (13.5 nm): Used for the most critical layers in advanced logic and DRAM.
- ArF Immersion (193 nm): Handles mid-critical layers with high overlay precision.
- Dry ArF / KrF / i-line (248–365 nm): Used for non-critical layers, analog, sensors, and packaging.
The XT:260 i-line tool fits into this stack by:
- Offloading non-critical layers from expensive EUV/ArFi tools.
- Reducing mask count and exposure cost for layers that don’t need sub-20nm resolution.
- Enabling high-throughput patterning for redistribution layers (RDL), interposers, and analog blocks.
This hybrid lithography flow is already standard in high-volume fabs. ASML’s Investor Day slides confirm that most chips use EUV for only 1–2 layers, while DUV (including i-line) handles the rest.
Cost Impact and Demand Boost
- Lower cost per wafer: Using XT:260 for non-critical layers cuts litho cost by up to 50% compared to using ArFi or EUV throughout.
- Higher fab utilization: XT:260’s >300 wafers/hour throughput helps balance fab load and reduce bottlenecks.
- Longer tool lifetime: ASML targets >20 years for XT-series tools, with modular upgrades and service packages.
- Demand driver: Lower litho cost makes ArF-EUV chips more viable for mid-range and consumer applications, expanding market reach.
Strategic Implication
This layered litho strategy is key to scaling chiplet ecosystems, AI accelerators, and mainstream SoCs. By combining XT:260 with ArF and EUV, fabs can optimize cost, throughput, and yield—without compromising performance where it matters.

PS
ASML says high interest.
I love anything interesting. Higher the better.
PSS
I eagerly await 4Q25...on big sales.
Which will ONLY be the start. |
