Chip Failure Analysis (FA)

Hypersemi provides professional third-party chip failure analysis services. Following a standardized outside-in, non-destructive-first methodology, we combine ATE electrical testing, X-Ray/CT and SAM non-destructive imaging, FIB/SEM cross-sectioning, EMMI/OBIRCH circuit-level localization and SIMS/XPS/AFM material characterization to rapidly pinpoint design flaws, process anomalies and application faults — across functional failures, short circuits, leakage and batch failures — shortening development cycles, improving yield and reducing field failure rates.

Standardized FA Workflow

Outside-in, non-destructive first

  1. Failure Replication & Electrical Isolation

    Based on failure background and ATE testing, replicate the fault, identify abnormal electrical parameters, and narrow down the failure zone.

  2. Non-Destructive Internal Inspection

    Using X-Ray CT, thermal imaging, SAM and other techniques to inspect internal package structure, thermal distribution and interface defects without damage.

  3. Microscopic Physical & Material Analysis

    Precise decapsulation and FIB cross-sectioning; SEM/TEM for nanoscale defects; EDS/SIMS for contamination and compositional analysis.

  4. Circuit & Device-Level Precision Localization

    EMMI and OBIRCH pinpoint leakage, shorts or opens at the transistor or circuit node level.

  5. Root-Cause Diagnosis & Improvement Recommendations

    Correlating electrical, physical and material data to construct failure mechanism models (electromigration, HCI, ESD damage) with actionable improvements.
