Advanced Packaging Process Control Through Full-Field Wafer Shape Using WFPI
<p>Backside power delivery networks and HBM stacks depend on wafer bonding with tight pitches and overlay budgets, and even small bonding-induced distortions can turn into yield loss in downstream CMP, lithography and stacking. Traditional metrology often can’t deliver fast, full-wafer, non-destructive measurements at the speed high-volume manufacturing requires.</p>
