Project description
Enhanced chiplet architecture for low-energy consumption embedded systems
Embedded systems face challenges with high-performance processors, including the size of cooling solutions and overall energy efficiency. Chiplet architecture provides a modular approach to microchip design and is considered the next advancement in semiconductor technology. The EIC-funded COOLBRAIN project aims to enhance chiplet architecture for embedded systems and smart devices, with a focus on AI. It endeavours to reduce hotspots through advanced cooling and energy harvesting, using the near-field super-Planckian effect to convert thermal energy into electricity. The project will develop nanoscale diamond technologies for low-temperature applications and create heat spreaders with conformal cavities. By integrating these solutions, it seeks to lower operating temperatures in high-performance computing and recover up to 30 % of thermal energy.

Indeed, embedded systems face with a number of challenges when it comes to using processors with high computing, such as the size and weight of cooling solutions and the total energy efficiency of the system, including its thermal management system.
At its core, COOLBRAIN is focused on the development of two highly advanced and innovative solutions for the reduction of hotspots through high-performance cooling and high-efficiency energy harvesting.
NEAR-FIELD SUPER-PLANCKIAN ENERGY HARVESTING: COOLBRAIN will explore all the potential of near-field super-Planckian effect to convert a maximum of the thermal energy on electricity. For it, three complementary technologies will be developed at nanoscale for the energy emission and energy reception and high-precision assembly.
CHIPLET EMBEDDING PROCESS IN DIAMOND HEATSPREADER: COOLBRAIN’s expertise on diamond-based technologies will be applied to develop nanoscale diamond capping technology at low temperatures ensuring physical integrity of advanced silicon nodes technologies. In complement, advanced diamond heatspreader with conformal cavities will be developed through high-precision drilling processes.
At the circuit-level, the combination of both solutions will allow to decrease the operation temperature of high-performance computing – decreasing the leakage current of very advanced silicon nodes, improving reliability and performance – and to improve the total efficiency of the system by recovering up to 30% of the thermal energy dissipated.
