Photoluminescence Inspection Is Changing How Manufacturers Protect Yield In SiC And GaN Devices

Electric vehicles, fast-charging infrastructure, renewable energy systems, and industrial power conversion are redefining what power semiconductors need to deliver: higher voltages, higher power densities, faster switching, and longer lifetimes. To meet these demands, manufacturers are increasingly turning to wide-bandgap materials like silicon carbide (SiC) and gallium nitride (GaN). SiC has become the material of choice for high-voltage applications such as traction inverters, onboard chargers
