The application of Raman and photoluminescence analysis in gallium nitride is reshaping quality control standards in semiconductor manufacturing. These techniques enhance detection accuracy of crystal defects and stress states, directly boosting performance in LEDs, lasers, and power devices. As chip nodes approach 2nm, even minor material variations can drastically impact yield, pushing the industry to adopt advanced characterization tools. Supply chain dynamics are shifting toward domestic capabilities, especially amid U.S.-China tech decoupling, where self-reliance in metrology is increasingly critical. Competitors may pursue M&A or partnerships to strengthen their detection capabilities and maintain market dominance. In the next 12 months, optical characterization of GaN-based materials will become a key strategic lever in the SiC and GaN co-existing power device market, intensifying technical differentiation.
