Intel 18A High-NA EUV Lithography Passes 1 Million Wafers

Intel's foundry division has processed more than one million wafers using its High-NA EUV lithography technology. This milestone signals that the company is moving past the experimental phase and into volume manufacturing for its most advanced nodes. Buyers of next-generation processors should watch this closely, as it confirms the availability of the tools needed to produce high-performance silicon at scale.

Intel 18A High-NA EUV Lithography Passes 1 Million Wafers

The High-NA EUV system represents a significant upgrade from traditional extreme ultraviolet lithography. Intel has deployed at least three of these machines in its Oregon facility to support production runs. This equipment targets the Intel 18A process node, which serves as a critical foundation for the company's upcoming Panther Lake processor family.

• High-NA EUV Wafers Processed: Over 1 million
• High-NA EUV Numerical Aperture: 0.55
• Traditional EUV Numerical Aperture: 0.33
• High-NA EUV Machines Deployed: At least 3
• Process Node: Intel 18A

The core technical difference lies in the numerical aperture, which jumps from 0.33 in standard EUV to 0.55 in the High-NA variant. This increase allows for finer pattern definition on the silicon surface. Intel states that the technology simplifies complex multi-patterning processes that were previously required for dense circuitry.

Performance metrics for the Intel 18A layers produced with High-NA EUV meet internal expectations for overlay accuracy, throughput, and tool uptime. Intel reports that these layers perform on par with or better than those made with traditional EUV. The company is using this data to benchmark the new technology against older methods directly.

We have been tracking High-NA EUV Lithography closely and previously covered the Intel 18A Panther Lake Chips Ship. Intel's foundry division has achieved another key breakthrough in advanced chip manufacturing, with its foundry division announcing that the cumulative number of wafers processed using High-NA EUV technology has exceeded 1 million.
