BLNKK's current understanding
Please check the details- Structure / bonding interface
- Insulating liner between TSV copper and silicon
- Observation stage
- Via formation, after liner deposition or copper filling, and bias verification
- Phenomenon to localize
- TSV-to-substrate leakage or dielectric breakdown
- Engineering decision
- Use vertical-interconnect-to-substrate insulation measurements to guide liner-integrity assessment or contamination sampling
- Sample evidence still required
- How do electrode area, TSV count or density, and substrate doping affect the aggregate measurement?
Paths to assess first
Paths serve different purposes and can be combined01
Verify TSV-to-bulk low-current measurementsFirst control aggregate topology and measurement background
First02
Sample liner depth and targeted integrityAlign the bulk path and retain samples
First03
Liner / contamination process comparisonsEstablish valid measurements before comparing stages
FirstCurrent candidate solutions
Sample suitability still needs confirmationAssess the setup for TSV-to-bulk low-current measurementsTektronix / Keithley · Can help answer: Published guarding and background methods can support measurement needs once topology and original bias conditions have been confirmed.
→Assess targeted TSV liner cross-sections and material analysisASE · Can help answer: Location- and depth-targeted FIB and material sampling can be planned for retained samples, with artifact controls preserved.
→Joint review of leakage paths, liners, and contaminationBLNKK engineering review request (provider unconfirmed) · Can help answer: Compare integrity and contamination hypotheses only when valid measurements, retained depth samples, and stage controls are all available.
