Intel Adopts ASML's High NA EUV Tool for Panther Lake Chip Production

Intel Corp. has started using ASML's next-generation lithography equipment to produce a portion of its flagship Panther Lake laptop chips, according to a statement from ASML on Tuesday. This move marks a significant step in integrating the cutting-edge, high-cost technology into a commercial manufacturing flow.

A Strategic Adoption

Following experiments that began in 2024, Intel is now employing ASML's high numerical aperture (High NA) extreme ultraviolet (EUV) machine for specific layers of the Panther Lake processors. The company said this limited production run will allow both Intel and ASML to gather critical data and optimize the equipment for broader use.

The Panther Lake chips are fabricated using Intel's 18A manufacturing process, which already utilizes ASML's standard EUV lithography machines. Lithography is a foundational process in chipmaking that uses light to print intricate circuit patterns onto silicon wafers. Intel declined to comment on the announcement.

High-Stakes Technology

The semiconductor industry has been closely watching for the adoption of High NA EUV tools, debating the economic and technical inflection point for their deployment. The systems are essential for creating the smaller, more complex features required for future generations of advanced microchips.

However, the transition comes with significant challenges:

• Cost: A High NA EUV machine costs approximately $400 million, double the price of a standard EUV system.
• Complexity: The tools are technically difficult to integrate into existing high-volume manufacturing processes.

Context and Timeline

Intel has positioned itself as an early adopter of the technology, having received the industry's first High NA tool in 2024 at its research and development site in Hillsboro, Oregon. The facility is where the company develops its new manufacturing techniques, and this move into partial production represents the next phase of its High NA strategy.
