Strain profiling
Strain in multilayer thin-film compound semiconductors can cause defects, dislocations, and piezoelectric fields, which affect device performance.
Many companies and research institutes are working to reduce this strain. However, since the actual strain distribution in the epi layer cannot be directly measured, improvements are usually confirmed only by observing changes in device performance.
AccuOptotec has developed a method to directly measure strain distribution in multilayer semiconductors using precision diagonal polishing (within 1 degree) and SERS analysis. This technique has been successfully applied to GaN-based blue LEDs, AlGaN DUV-LEDs, and GaN-on-Si power semiconductors, providing meaningful results.
This is the only method that directly verifies strain effects and improvements, making it a breakthrough in semiconductor research.
