Local interface voids after hybrid bonding
Correlate defect locations with pre- and post-bond data to separate particle, flatness, wafer-warpage, and bonding-condition effects.
Cu / dielectric hybrid-bond interface · Post-bond or post-anneal inspectionRising thermal resistance during power cycling
Track thermal, electrical, and imaging metrics together to distinguish die attach, interconnects, and external thermal interfaces.
Overall IGBT / SiC power-module thermal path · Active power cycling and interrupted inspectionUnderfill voids and post-cure delamination in large multi-die packages
Inspect filling, curing, and interface integrity separately. Material claims cannot replace defect validation.
Capillary underfill paths and polymer interfaces beneath dies · Filling, curing, and subsequent comparisonsUneven heat-spreader contact and local hot spots in multi-die packages
Separate heat-source distribution from TIM contact conditions before comparing thin interface materials and thermal paths.
TIM1 / TIM2 and heat-spreader contact interfaces · Initial assembly and controlled contact verificationIntermittent opens in stacked substrate microvias after reflow
Use continuity data throughout the thermal history to locate weak interfaces; room-temperature cross-sections alone cannot support release.
Organic-substrate stacked microvias and target-pad interfaces · Reflow thermal history and room-temperature recoveryKnow the problem scope? Explore six technology directions
Technology directions help you explore methods. They do not establish a standard solution or sample suitability.
Before you get started
What will I get from Navigator?
Explore technical paths and candidates related to an engineering problem. Compare intended uses, applicability and sources, identify missing information and key questions, and download an assessment preparation summary. These outputs help you prepare your next technical assessment. Applicability still requires samples, measurements and supplier confirmation.

You can browse engineering problems, suppliers and solutions, and compare solutions without signing in. Sign in to save cloud copies of cases, view account-linked inquiry history, claim a supplier company, propose updates or reply with supplier authorization. Supplier permissions also require a reviewed claim or an owner invitation.

The supplier catalog is compiled from public sources. Problem-specific candidates include context for the problem, structure and stage. A listing or candidate does not establish verified applicability, supplier endorsement or a purchasing recommendation. Read the sources and limitations together, then confirm your conditions with the supplier.
