Abstract
We propose a non-destructive method to measure a depth of Through-Silicon Via (TSV) using Terahertz Time-Domain Spectroscopy (THz-TDS). TSV with high aspect ratio could be measured from the phase-shift of transmitted THz pulse. We also succeeded in imaging the difference between two areas corresponding to TSVs and unprocessed Si wafer.
