Materials like silicon carbide (SiC) and gallium nitride (GaN) provide the exceptional thermal conductivity and high breakdown voltages needed for electric vehicle powertrains and high-frequency power electronics. 📉 However, high-temperature processing steps introduce severe thermal gradients. This leads to mechanical warping, micropipes, line dislocations, and trace metallic contamination that drastically degrade device efficiency and threaten overall wafer uniformity. 💡 The solution lies in advanced material characterization. By synergizing multiple analytical techniques on advanced correlative platforms, manufacturers can completely transform their quality control workflows: 🔹 Raman Spectroscopy maps residual mechanical stress and structural defects across the crystal lattice. 🔹 Photoluminescence (PL) isolates trace metallic contamination and problematic doping variations. 🔹 Ellipsometry provides precise, non-destructive tracking of thin-film thickness and uniformity. Integrating these complementary tools into a single testing ecosystem eliminates metrology bottlenecks, prevents premature device failure, and maximizes manufacturing yield. 🔗 Read the full breakdown of how multimodal spectroscopy is shaping the future of WBG semiconductor fabrication at the link here: https://horiba.link/ohy
