BLNKK's current understanding
Please check the details- Structure / bonding interface
- Unbonded Cu/dielectric surfaces
- Observation stage
- After CMP, cleaning and activation, before bonding
- Phenomenon to localize
- Surface topography, particles or chemical conditions outside the target process window
- Engineering decision
- Use traceable measurements of surfaces awaiting bonding to decide release, rework or hold and establish comparisons
- Sample evidence still required
- Who validates and approves the process’s release window and inspection coverage?
Paths to assess first
Paths serve different purposes and can be combined01
Pre-bond multiscale topography and particle inspectionCompare measurement coverage across target regions
First02
Cleaning/activation and wait-time comparisonsSeparate equipment actions from surface conditions
First03
Review of rework and release evidenceCheck rework tradeoffs and process-specific decision authority
FirstCurrent candidate solutions
Sample suitability still needs confirmationAssessment of pre-bond topography with AFM/AFPBruker · Can help answer: Public multiscale methods can compare local and longer-scale variation after CMP. Particle-inspection coverage requires separate confirmation.
→Assessment of EVG cleaning/activation process comparisonsEV Group · Can help answer: D2W cleaning and activation capabilities can be included in comparison requirements for the actual materials and waiting conditions.
→Joint review of surface release and reworkBLNKK engineering review request (provider unconfirmed) · Can help answer: Compile process-decision evidence only when topography coverage, surface chemistry/waiting and compatibility controls are complete.
→Next: confirm engineering conditionsUse 5 key conditions to adjust the assessment order, then choose solutions to compare.
