Reset filters 02 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 inspection Choose this problem → 06 Underfill 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 comparisons Choose this problem → 07 Uneven 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 verification Choose this problem → 10 Non-wetting, cold joints and opens in HBM thermocompression bonding Align joint-defect maps with temperature, pressure, and tilt records before evaluating bonding windows or surface treatment.
HBM thermocompression-bonded microbump joints · Per-die post-TCB inspection Choose this problem → 13 BGA head-in-pillow open joints Identify the unfused interface, then compare reflow thermal geometry, supply / placement, and wetting separately.
Package-ball / board-paste interface · First electrical test after board reflow Choose this problem → 14 TSV reveal height and backside coplanarity Separate relative Cu reveal height from full-wafer topography, then use staged thinning / reveal maps to define upstream, etch, or pre-bond surface requirements.

Explore six technology directions Technology directions help you explore methods. They do not establish a standard solution or sample suitability.
Technology directionAll directions Measurement, inspection and failure localization Simulation, modelling and life prediction Material properties and interface design Process equipment and window control Package structures and deformation compensation Reliability validation and failure analysis 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.

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.
Sign in → How are solutions compiled? Are candidates recommendations? 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.
