French Start-Up Garners Substantial Initial Financing Round

29 March 2024

With contributions from Asterion Ventures, Bpifrance and Fonds Régional Avenir Industrie Auvergne-Rhône-Alpes, Grenoble-located firm Diamfab just closed its 1st round funding. All together it has gained a total of Euro 8.7 million in capital investment.

Originally spun out of the Institut Néel research establishment, the start-up is focused on developing semiconductor devices based on the superior electrical and thermal properties that diamond possesses. Fabricated with synthetic diamond epitaxial layers, these devices will offer greater energy efficiency plus better temperature resilience than ones using either silicon-carbide (SiC) or gallium-nitride (GaN) substrates. Opportunities have already been identified for them to reduce power losses and lower the weight of power systems in relation to eMobility, renewable energy installations, power distribution networks, avionics, etc. 
According to Gauthier Chicot, Diamfab’s Chairman; "In the development of a cutting-edge industry like ours, each stage is essential. The pilot project will catalyze many discussions with our partners and strengthen our relationships. To be accompanied by investors who are committed to the industry and the climate, and above all who understand its constraints and links, is fundamental. We couldn't have hoped for better partners than those who have rallied around us with Asterion.”
"Diamfab is at the crossroads of many of today's challenges - industrial relocation, decarbonisation, strategic sovereignty. The technology we have developed makes it possible to reduce the historical carbon footprint of semiconductors considerably, and to do so by relocating a key industry for Europe, which is one of our investment priorities with Asterion. Industrial deeptech companies need calm, long-term support, and that's what we provide," adds Charles-Henry Choel of Asterion Ventures.
