BLNKK's current understanding
Please check the details- Structure / bonding interface
- Relative Cu-pad positions and electrical nets in hybrid bonding
- Observation stage
- Alignment, post-bond overlay and electrical testing
- Phenomenon to localize
- Pad misalignment, insufficient contact area or electrical opens
- Engineering decision
- Use correlations between overlay vectors and pad electrical data to determine alignment compensation or pattern correction
- Sample evidence still required
- Are mark-to-pad calibration and measurement uncertainty traceable?
Paths to assess first
Paths serve different purposes and can be combined01
Post-bond pad-overlay measurementFirst establish calibrated relative vectors for both sides
First02
Equipment alignment-compensation comparisonAlign open-circuit locations and control bonding history
First03
Joint review of patterns and bond interfacesSeparate local-pattern residuals from unbonded regions
FirstCurrent candidate solutions
Sample suitability still needs confirmationAssessment of EVG post-bond position measurementEV Group · Can help answer: D2W verification and W2W alignment options can be assessed separately for the actual platforms.
→Assessment of targeted pad/electrical alignment analysisASE · Can help answer: Any comparison route with complete inputs can support confirmation of electrical-localization and targeted-contact sampling capabilities.
→Joint review of equipment compensation and pattern correctionBLNKK engineering review request (provider unconfirmed) · Can help answer: Compare compensation levels only when equipment transforms, electrical data and local-pattern/surface comparisons all have complete inputs.
