Before everyone heads off for a well-deserved summer break, the CoolSem Technologies team gathered for the annual Summer Drinks. 🍹☀️   A big thank you to our amazing Happiness Committee Pieter Heersink and Natasha Gruginskie for organizing another great evening filled with good food, great conversations, and plenty of laughs. Now it is time to recharge the people behind our cool technology. Have a fantastic summer, everyone! 😎

🏆 Recognition is meaningful when it reflects the problem you are solving. Heat is rapidly becoming one of the biggest constraints on next-generation semiconductors. As device performance continues to increase, thermal management is rapidly becoming a critical bottleneck affecting efficiency, reliability, lifetime, and scalability. At CoolSem Technologies, we believe that thermal management must evolve from a supporting function to a core design consideration for next-generation semiconductor and photonic devices. We are proud that the Gerard & Anton Award 2026 recognizes CoolSem Technologies' mission to address this challenge through wafer-level thermal innovation, helping pave the way for cooler, more reliable and more manufacturable semiconductor devices. 👉 Read the full article: https://lnkd.in/e8AyPv3d

𝗜𝗺𝗽𝗼𝘀𝘀𝗶𝗯𝗹𝗲 𝘁𝗼 𝗶𝗴𝗻𝗼𝗿𝗲 𝘁𝗵𝗲 𝘀𝘁𝗿𝗲𝗻𝗴𝘁𝗵 𝗼𝗳 𝘁𝗵𝗲 𝗗𝘂𝘁𝗰𝗵 𝗱𝗲𝗲𝗽-𝘁𝗲𝗰𝗵 𝗲𝗰𝗼𝘀𝘆𝘀𝘁𝗲𝗺 🌐   CoolSem Technologies participated in the Hello Tomorrow 𝗚𝗹𝗼𝗯𝗮𝗹 𝗦𝘂𝗺𝗺𝗶𝘁, joining innovators, investors, corporates, and policymakers from across the international deep-tech community. After meeting with strategic partners, technology leaders, and members of the broader Dutch high-tech ecosystem, one message stood out: 𝗱𝗲𝗲𝗽 𝘁𝗲𝗰𝗵 𝗶𝘀 𝗮 𝘁𝗲𝗮𝗺 𝘀𝗽𝗼𝗿𝘁.   Building breakthrough technologies requires far more than a great idea or a strong engineering team. Success depends on an entire ecosystem of universities, research institutes, suppliers, manufacturing partners, customers, investors, and policymakers working together.   The Netherlands has built a remarkably strong ecosystem around deep technology, combining expertise in semiconductors, photonics, advanced manufacturing, materials, and high-tech systems within a uniquely concentrated geographic region.   A particular highlight of the summit was the Discover Dutch DeepTech pavilion, organized by Techleap, RVO - Netherlands Enterprise Agency, and TNO. By presenting Dutch innovation collectively rather than individually, these initiatives help companies access international opportunities that would be difficult to create alone.   At CoolSem Technologies, we are fortunate to be part of a strong and supportive innovation ecosystem. We are grateful for the support, expertise, and collaboration provided by PhotonDelta, PhotonicsNL, Eindhoven University of Technology, Radboud University, and the broader Brainport Eindhoven ecosystem.   As global competition in semiconductors, photonics, AI infrastructure, and advanced manufacturing intensifies, one thing becomes increasingly clear: The companies that succeed will not stand alone. They will be supported by the strongest ecosystems. 👉 Read our blog: Cool Technology, Warm Connections https://lnkd.in/etBhXGe6

At CoolSem Technologies, innovation starts with curiosity. We encourage our team to explore new ideas, technologies, and approaches beyond their immediate area of expertise. Last week, Rosalinda (Linda) van Leest attended the 𝗟𝗮𝘀𝗲𝗿 𝗣𝗿𝗼𝗰𝗲𝘀𝘀𝗶𝗻𝗴 𝗼𝗳 𝗪𝗶𝗱𝗲-𝗕𝗮𝗻𝗱𝗴𝗮𝗽 𝗠𝗮𝘁𝗲𝗿𝗶𝗮𝗹𝘀 workshop organized by Fraunhofer-Gesellschaft ISE in Freiburg, where she connected with researchers from different disciplines and gained insights into emerging processing techniques. These kinds of learning opportunities are invaluable. Exposure to new materials, manufacturing methods, and scientific perspectives often sparks the ideas that lead to breakthrough engineering solutions. We are pleased to see the inspiration and practical insights Linda brought back to support the ongoing development of our WaLTIS® technology. After all, advancing semiconductor cooling requires not only deep expertise, but also the curiosity to keep learning.

𝗔 𝗽𝗿𝗼𝗱𝘂𝗰𝘁𝗶𝘃𝗲 𝘄𝗲𝗲𝗸 𝗮𝘁 Hello Tomorrow! Andre van Geelen and Pieter Heersink met with partners, investors, and members of the Dutch high-tech ecosystem to discuss the future of advanced semiconductor cooling. As always, we were proud to represent CoolSem Technologies and our mission to keep next-generation semiconductors 𝘾𝙤𝙤𝙡 𝙖𝙩 𝙩𝙝𝙚 𝘾𝙤𝙧𝙚. Among the highlights were valuable exchanges with Constantijn Van Oranje-Nassau and Peter Wennink, John Bell and HighTechXL, alongside many other leaders shaping the future of European deep tech. We look forward to continuing the conversations. 🙏 Thank you Netherlands Enterprise Agency RVO and Techleap and Lech Bakhuizen van den Brink for hosting a variety of memorable events at and around the orange Discover Dutch DeepTech booth.   🤝 Special thanks to Liz Duijves, Elise Lie, and Gert-Jan Vaessen from Invest-NL, and Iris Schut from TNO for the valuable conversations and support throughout the event. 🙌 And congratulations to Emma Carnus, Orlando Ramírez Galindo, and Fannie Delavelle for delivering an exceptionally well-organized edition of the Hello Tomorrow Global Summit. The quality of the event, the participants, and the discussions were truly impressive.

We’ll be at Hello Tomorrow in Amsterdam on 11–12 June. If you’re working on thermal bottlenecks in semiconductors, photonics, RF, power devices or AI/HPC hardware, let’s connect. Come meet us at booth number 20 — we’d be happy to exchange ideas and explore where advanced thermal management could make a difference.
