Intel Foundry reported a key milestone in advanced semiconductor manufacturing with completed assembly of the industry’s first commercial High Numerical Aperture (High NA) Extreme Ultraviolet (EUV) lithography scanner, located at the company’s Hillsboro, Oregon, R&D site. Intel’s TWINSCAN EXE:5000 High NA EUV tool from lithography leader ASML is now going through calibration steps in preparation for production of Intel’s future process roadmap. The new tool has the ability to dramatically improve resolution and feature scaling for next-generation processors by changing the optics design for projecting printed images onto a silicon wafer.
“With the addition of High NA EUV, Intel will have the most well-rounded lithography toolbox in the industry, enabling the company to drive future process capabilities beyond Intel 18A into the second half of this decade.”
—Mark Phillips, Intel Fellow and director of Lithography, Hardware and Solutions for Intel Foundry Logic Technology Development
Why It Matters: High NA EUV tools will play a critical role in advanced chip development and the production of next-generation processors. Intel Foundry — the industry’s first mover on High NA EUV — will be able to deliver never-before-seen precision and scalability in chip manufacturing, enabling the company to develop chips with the most innovative features and capabilities that are essential for driving advancements in AI and other emerging technologies.
ASML recently announced it has printed the first-ever 10 nanometer (nm) dense lines in the High NA lab at the company’s headquarters in Veldhoven, Netherlands. These are the finest lines ever printed, setting a world-record resolution for an EUV lithography scanner. This demonstration validates the innovative High NA EUV optics design from ASML partner Zeiss.
Groundbreaking images were printed after the tool’s optics, sensors and stages completed coarse calibration — a stepping-stone to running at full specification. ASML’s ability to print 10nm dense lines with a full field optical lithography system is a key step toward readying the High NA EUV tool for commercial use.
How It Works: When combined with Intel Foundry’s other leading process technology capabilities, High NA EUV is expected to be able to print features up to 1.7x smaller than existing EUV tools. This will enable 2D feature scaling, resulting in up to 2.9x more density. Intel continues to lead the way forward for ever-smaller, ever-denser patterning that drives Moore’s Law across the semiconductor industry.
Compared to 0.33NA EUV, High NA EUV (or 0.55NA EUV) can deliver higher imaging contrast for similar features, which enables less light per exposure, thereby reducing the time required to print each layer and increasing wafer output.
Intel expects to use both 0.33NA EUV and 0.55NA EUV alongside other lithography processes in developing and manufacturing advanced chips, starting with product proof points on Intel 18A in 2025 and continuing into production of Intel 14A. Intel’s approach will optimize advanced process technology for cost and performance.
About Intel’s Role: Intel has collaborated with ASML for decades to drive the evolution of lithography from 193nm immersion lithography to EUV, and now to High NA EUV. The result is the TWINSCAN EXE:5000, one of the most advanced manufacturing tools built. The adoption of High NA EUV lithography puts the company at the forefront of Moore’s Law scaling, moving the company well into the Angstrom Era.
The TWINSCAN EXE:5000 system was transported to Oregon in more than 250 crates inside 43 freight containers. These were loaded onto multiple cargo planes that landed in Seattle. They were then transferred to 20 trucks for the drive to Oregon. The total weight of each new system is more than 150 metric tons. (See infographic/fact sheet for more information.)
Intel announced its plans to adopt High NA EUV in 2021, and in 2022 Intel and ASML announced their continued collaboration to drive this advanced technology. Intel plans to acquire the next-generation TWINSCAN EXE:5200B system, with a productivity of more than 200 wafers per hour, making the company an industry first mover on this system as well.
More About High NA EUV: High NA EUV lithography is an evolutionary step beyond EUV lithography, which uses a wavelength of light (13.5nm) that does not naturally occur on Earth. The light is created by a powerful laser hitting a droplet of tin heated to a temperature of almost 220,000 degrees Celsius — almost 40 times hotter than the average surface temperature of the sun. This light reflects off a mask containing a template of the desired circuit pattern, and then through an optical system built with the most accurate mirrors ever fabricated.
Numerical Aperture (NA) is a measure of the ability to collect and focus light. By changing the design of the optics used to project a pattern onto a wafer, High NA EUV technology enables a significant step forward in resolution and transistor size. The ability to create transistors at these smaller dimensions also requires new transistor structures and improvements in other process steps that Intel is developing in parallel to the integration of the first High NA EUV system.
About Intel Foundry’s Oregon R&D Site: Oregon is at the heart of Intel’s process technology research and development. To make way for this latest generation of lithography tools, Intel opened Mod 3 in 2022, a more than $3 billion investment in expanding its D1X fab in Oregon, adding 270,000 square feet of clean room space.
Translating research into manufacturable, leading-edge, real-world products is where Intel has excelled for more than 50 years. Investing in R&D and in tools such as High NA EUV will help expand the ability to manufacture chips domestically and revitalize U.S.-based R&D to meet national economic and security objectives. Expansion of R&D and use of the latest lithography tools in Oregon will also help create new jobs and attract the best talent to the Northwest. Intel is poised to help accelerate the next generation of U.S. semiconductor technology and manufacturing today and into the future.
