Problem
Modern power electronics face challenges related to heat dissipation, limiting performance and reliability due to the thermal conductivity limitations of silicon and other traditional materials. Overheating in chips leads to reduced efficiency, increased energy consumption, and potential electronic waste.
Solution
PROUD develops diamond-based wafers utilizing chemical vapor deposition (CVD) diamonds for power electronics, leveraging diamond's superior thermal conductivity—15 times greater than silicon—to enhance heat dissipation. These wafers act as heat spreaders, efficiently drawing heat away from high-power components, which improves performance, extends chip lifetime, and reduces operating temperatures. The technology enables smaller, lighter, and more efficient electronic systems, contributing to lower energy consumption and reduced electronic waste. PROUD's diamond solutions are sustainable, 100% Swiss made, and offer an environmentally friendly alternative to mined diamonds.
Target Audience
The primary target audience includes manufacturers of power electronics, semiconductor chips, 5G infrastructure equipment, medical implants, aerospace components, and quantum computing systems.
