PROUD Technology: A Deeptech and Purpose driven CVD Lab-Grown Diamond technology company. PROUD Tech and EPLF have developed a technology (patented) to grow electronic-grad (extremely pure quality) CVD diamond on top of semiconductors and electronics with promising results and impacts: - 50°C of temperature reduction - Electronic lifetime multiply by 5 - Thermal dissipation capacity multiply by 7 (versus Si or GaN) The energy consumption of semiconductors will drastically be reduced, which will be translated in reduction of GHG emission. PROUD Tech has two main activities, one focusing on High-Tech (Power Electronics and Photonics) and the second focusing on Luxury (Watchmaker and Jewelry). “ICT’s share of global greenhouse gas emissions actually lies between 2.1-3.9 %. ICT GHG emissions could be as high as 8 % by 2025” Our first goal in High-Tech is to drastically reduce the energy consumption of electronics by working directly on the semiconductor (wafer Si-GaN). We are currently working on growing a micro-layer of electronic-grade diamond on top of wafers Si-GaN at an industrial scale. “Natural diamond extraction has strong negative impacts on the environment, health, water usage, social justice and air quality” For 1 carat of natural diamond extracted from the Earth: - 1000+ tons of earth removed - 3000+ liters of water used - 500+ kg of air pollution released - 100+ kg of carbon dioxide emitted
