SemiQon's Award-Winning Cryogenic Chip Technology

In a significant milestone for quantum computing and space technology, SemiQon, in collaboration with VTT, has captured the first prize in the "Impact Expected" category at the EARTO awards held in Brussels on October 14, 2025. This recognition comes as a result of their groundbreaking innovation in cryogenic CMOS (complementary metal-oxide semiconductor) chips. These advanced chips demonstrate the ability to operate at extremely low temperatures, thereby enhancing functionality and unlocking new opportunities in various fields, particularly quantum computing and aerospace applications.

Himadri Majumdar, the CEO of SemiQon, expressed his pride in this achievement, stating, "Although cryogenic electronics may seem niche today, they will soon become mainstream first driven by quantum computing and aerospace. SemiQon, leveraging VTT's foundational work, is proud to be driving this shift globally. We're truly honoured to receive this award, which highlights the promise of our technology and the impact we aim to create."

— ## Powering a New Era of Technology
The technology behind SemiQon's cryo-CMOS chips sets a new standard in energy efficiency and performance. Unlike traditional CMOS technologies that suffer from energy consumption and heat dissipation issues, SemiQon's innovation boasts a staggering 50-90% reduction in power consumption for space applications. This not only minimizes costs associated with quantum computer readout but could lead to an overall long-term cost reduction of over tenfold. Furthermore, by eliminating the necessity for separate cooling infrastructures, the technology opens the door to a more sustainable future for supercomputers and data centers. This approach has the potential to save the global economy an estimated USD 20-30 billion in annual cooling costs alone.

— ## A Legacy of Innovation
The foundation of this innovation traces back to VTT, which originally developed the cryogenic CMOS technology. In 2023, SemiQon spun off from VTT with a focused mission to enhance the functionality of cryogenic chips, particularly for applications in quantum computing and space technology. The chip manufacturing takes place at European pilot line foundries such as Micronova and the future Kvanttinova hub in Espoo, Finland, which is poised to become a significant player in the semiconductor landscape. Micronova is recognized as the largest semiconductor R&D cleanroom facility in the Nordics.

— ## Broader Impact and Future Vision
The implications of cryogenic CMOS technology extend far beyond mere advancements in quantum computing. According to Tauno Vähä-Heikkilä, Vice President of Microelectronics and Quantum Technology at VTT, innovations such as these contribute significantly to societal growth while enhancing Europe's position in global competitiveness and addressing critical challenges:

"Innovations such as the cryo-CMOS offer the opportunity to renew businesses and drive significant growth to society. This recognition goes beyond a single breakthrough. It celebrates the vital role that research and technology organizations play in strengthening Europe's competitiveness, building resilience, and addressing global challenges."

Additionally, the potential contributions of cryogenic CMOS technology align with numerous United Nations Sustainable Development Goals, empowering advancements in energy-efficient electronics, environmental monitoring, and space exploration.

— ## The Path Ahead
The market for cryogenic CMOS is projected to expand significantly, currently valued at over EUR 3 billion, with estimates suggesting growth to EUR 10 billion by 2030. This growth potential is attributed to the increasing demand for efficient semiconductor technologies across various industries.

In its early journey, SemiQon successfully secured funding through competitive grants and consortium projects, including a recent EUR 2.5 million award from the European Innovation Council in spring 2025 and an additional EUR 15 million in equity funding. Such financial backing underscores the confidence in SemiQon's vision to spearhead developments in quantum and cryogenic technologies while ensuring their solutions remain commercially viable and ready for mass production.

As SemiQon prepares for customer product testing within the next two years, the wait is over for those anticipating the benefits of this pioneering cryogenic CMOS technology. The company stands as a testament to the successful transition of advanced research into commercial reality—promising a future where efficiency, sustainability, and innovation walk hand in hand.
