Imec and Mitsui Chemicals Forge a Pioneering EUV Lithography Alliance

In an ambitious strategic move, Imec, the Belgian titan in nano-electronics innovation, and the Japanese chemical conglomerate Mitsui Chemicals have forged a partnership set to redefine the landscape of semiconductor manufacturing. Together, they are on a quest to commercialize a breakthrough component in extreme-ultraviolet (EUV) lithography systems—a technology that is key to advancing the very fabric of computing power in sync with the relentless march of Moore’s law.



Focusing on EUV Pellicles:

The partnership highlights the development of EUV pellicles, which are ultra-thin, transparent sheets designed to shield photomasks from destructive contamination during chip production. Photomasks are the stencils of the semiconductor world, and with investment reaching dizzying sums, the prevention of particle contamination is paramount in safeguarding production yield.

  1. Crafting Immaculate Protection: Imec and Mitsui Chemicals are concentrating their efforts on advancing pellicle technology to accompany the anticipated upsurge in EUV lithography light source power, expected to cross 600 W by the mid-2020s.

  2. The CNT Edge: The focus of the Imec–Mitsui collaboration rests on harnessing carbon nanotube (CNT) technology to fabricate pellicles that are not only capable of enduring over 1000 W of EUV power but also boast superior transparency to both EUV and deep-ultraviolet (DUV) light—facilitating inspection and quality control processes essential in modern lithography.

  3. Trailblazing Transparency: The cutting-edge CNT-based pellicles from Imec and Mitsui transmit an astonishing above 94% of EUV light, showcasing their exceptionally low EUV reflectance and outstanding physical strength—a combination that positions these membranes as critical for the future of nano-scale lithography.

Market Implications and Investment Insights:

The partnership between Imec and Mitsui Chemicals is a testament to the innovation and foresight within the semiconductor sector, particularly in the niche of next-generation EUV lithography technology.

  1. Semiconductor Renaissance: Imec's deep knowledge in CNT membrane performance, combined with Mitsui's technology integration capabilities, signals a significant opportunity for investors. An eye on companies focusing on nanomaterials, especially CNT technologies, could be key in tapping into the semiconductor industry's potential growth.

  2. Protective Technologies at Forefront: The surge in demand for high-performance and reliable EUV pellicles presents a niche market with potentially high returns, emphasizing investment in companies like Mitsui Chemicals that are actively innovating in protective solutions for high-end semiconductor applications.

  3. Readying for High-Power EUV Adoption: With global semiconductor players showing "strong interest" in the properties of CNT-based pellicles, the roadmap towards higher power EUV systems suggests a readiness for transformative shifts in chip manufacturing. This pivot heralds a potential windfall for stakeholders who invest early in this emerging technology domain.


As the gears turn towards a new dawn in semiconductor fabrication, the pioneering partnership between Imec and Mitsui Chemicals stands as both a beacon and a bellwether—foretelling the direction of a critical industry. For investors and tech enthusiasts alike, watching this space could spell the difference between leading the charge and playing catch-up.
