SemiQon’s Cryo CMOS Technology for Space Applications
Universe-Targeting SemiQon Technology: European Space Agency-Assisted Cryo CMOS Solution Addresses Extreme Temperature Issues SemiQon, a leader in silicon-based scalable quantum technologies, is employing its world-first cryogenic CMOS (cryo-CMOS) technology to solve space electronics problems. The venture, which intends to commercialise quantum computers, entered the space industry with help from ESA BIC Finland, the ESA's business incubation program.
Traditionally, space technology devices cannot survive high temperatures, prompting this alliance. Many multinational organisations, including NASA and DARPA, have identified this problem, which causes electronics to operate badly over time. Space Electronics Revolution SemiQon's main invention is the first cryogenic CMOS transistor optimised for temperatures below 1 Kelvin. Finland's VTT Technical Research Centre spun off this technology to build quantum integrated circuits (IC Chips) and scale quantum computers. However, the researchers immediately realised that creating the “world's first and best cryogenic CMOS” may assist areas beyond quantum, such as space electronics. Space applications benefit from Cryo CMOS technology, which makes devices smaller and more efficient. Compared to typical electronics at cryogenic temperatures, the technology reduces power usage by 1000 times and 90% in space applications. Heat dissipation is 1000 times lower than ordinary transistors, which simplifies delicate electronics design. This integration lets control electronics be placed directly at cryogenic temperatures, eliminating the need for massive, power-hungry room-temperature components. Instead of pricey new facilities for exotic materials, the method uses silicon CMOS and current semiconductor infrastructure. Working with ESA BIC Finland SemiQon approached ESA BIC Finland in spring 2025 after realising space applications were possible but needing industry understanding. The startup was instantly accepted into the specialised business incubation program, which selects businesses based on European criteria that emphasise IP, breakthrough technologies, and unique business models. “When SemiQon approached the program, the company was already technologically mature for its age, having achieved significant milestones and begun building a substantial team, including commercial resources,” said Kaisa Ahonen, Manager at ESA BIC Finland. Ahonen called SemiQon's strategy “proactive”. “Space is obviously a challenging operating environment for all devices, so we must work with the right experts to better understand the challenges and opportunities our technology could offer,” said SemiQon Director of Business Development Yukihisa Tsuruta. Finding Space Uses The BIC initiative has allowed SemiQon to speak directly with ESA technical specialists, which has proved very helpful. Tsuruta, who described the fruitful conversations, said the specialists were immediately educated about the technology and its potential solutions. These consultations revealed several space sector application areas: X-ray machines, bolometers, and infrared sensors may use telescopes. Communications: Digital beam creation for 5G and other advanced satellite systems. Exploration: Providing a more reliable and effective solution for Mars and Lunar exploration electronics, where extreme temperatures and power limits are issues. Future prospects and assistance ESA BIC Finland offers financial and technical support to ambitious entrepreneurs to help them reach their space potential. The incubator offers technical consults, trainings, events, equity-free investment, and strong national and European networks. Ahonen was optimistic about the cooperation, saying SemiQon may benefit from the incubator's network. “We of course hope to see SemiQon's technology in space on day – maybe as part of an ESA mission,” Ahonen said, despite the lengthy process of sending equipment in space. EARTO (the European Association of Research and Technology Organisations) awarded SemiQon and VTT first place in the “Impact Expected” category for their Cryo CMOS chip innovation in Brussels on October 14, 2025. This alliance follows another company milestone. This technology enabled advanced CMOS functionality at cryogenic temperatures, enabling space applications and quantum computing.
