During semiconductor manufacturing and chip packaging, thermal warpage in wafers is a critical factor leading to issues such as chip cracking, open solder joints, circuit shorts, device performance drift, and even total system failure. Leveraging the advantages of non-contact, full-field, and micron-level measurement, Digital Image Correlation (DIC) technology—specifically 3D strain measurement systems—can capture comprehensive data on 3D warpage morphology, displacement fields, and strain fields across the entire temperature range. This provides a quantitative basis for optimizing wafer processes, designing for thermal matching in packaging, and validating the reliability of automotive-grade chips.
