IM4000II substrate-interconnect ion-milled cross sections
Hitachi High-Tech · Reliability qualification and failure analysis
- Purpose
- Prepare cross-sectional evidence of metal/polymer interfaces after locating a substrate-microvia anomaly.
- Technical approach
- IM4000II uses broad argon-ion sputtering for cross-section or flat milling before microscopy.
- Scope of use
- Multilayer specimens must be cut, mounted and positioned; milling modules and CTC cooling require configuration confirmation.
- Limitations and open questions
These evaluation considerations are compiled by BLNKK from public information. They are not supplier guarantees or a mandatory submission checklist.
Scope and limitationsPreparation removes material. Heat damage, redeposition and sampling representativeness need review; the tool does not measure continuity or independently identify failure cause.
What to prepareBLNKK suggests preparing anomaly coordinates, specimen geometry/stack, allowable cutting area, sensitive materials, target plane and prior electrical/imaging evidence.
Confirm with the supplierConfirm modules, CTC cooling or transfer accessories, milling/localization conditions, potential artifacts and follow-up microscopy.
- Public evidence
- Hitachi’s page and IM4000 II brochure describe preparation and options, separately from IM5000 wide-area capability.
