Unique GaN-on-Silicon expertise & know-how

EasyGaN is a startup providing epitaxy solutions to unleash the full potential of GaN-on-Silicon technology. Located in Sophia Antipolis, EasyGaN is a CRHEA-CNRS spin-off, an internationally recognized Research Center with 20+ years of experience in the epitaxial growth of GaN. We develop epiwafers for the GaN on Silicon semiconductor market using Molecular Beam Epitaxy. Our first product is a very thin high-quality Aluminium Nitride (AlN) layer grown on top of a silicon wafer. This so-called ''AlN template'' is already available and is currently being tested by customers as ideal starting point for their GaN epitaxy. In addition, we are currently developing an ultra-thin GaN on Silicon epiwafer for the Radio Frequency 5G millimeter wave device market.


Our team has extensive experience in the epitaxial growth of GaN on silicon and  the realization of semiconductor devices.
