PHEMOS-X electrical fault localization
Hamamatsu Photonics · Engineering measurement and characterization
- Purpose
- Repeatable leakage needs a narrower target for physical failure analysis.
- Technical approach
- PHEMOS-X detects weak emission or thermal signals with selected detectors and overlays them on pattern images.
- Scope of use
- Use semiconductor fault localization with reproducible electrical stimulation, optical access and appropriate detector configurations.
- 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 limitationsDetectability varies with samples and configuration. Localization does not measure TSV liner depth or establish root cause.
What to prepareBLNKK recommends preparing leakage curves, bias conditions and sample/metal-layer information, with reference samples and subsequent cross-section plans.
Confirm with the supplierConfirm detectors, optical access, bias/probing and required laser or TD options; check signal detectability on actual samples.
- Public evidence
- The official page and July 2025 brochure describe emission, thermal lock-in and optional laser/TD imaging.
