Every invalid return drains warranty reserves while tying up refurbishment capacity your fab can't afford to lose.
High NFF rates in semiconductor warranty returns stem from inadequate root cause detection at fab scale. AI analyzes telemetry patterns and failure signatures to validate claims before return authorization, reducing invalid returns by 40-60% while protecting warranty reserves.
Semiconductor OEMs face unpredictable warranty costs when NFF returns bypass validation. Without pattern detection at scale, invalid claims bleed through manual review, forcing conservative reserve accounting that impacts margin guidance.
Invalid returns consume scarce refurbishment capacity. Lithography and etch tools require weeks of tear-down and rebuild. Every NFF return delays legitimate repair work, creating cascading fab downtime for your customers.
Manual claim review cannot detect sophisticated fraud patterns across thousands of fab installations. Fraudulent claims exploit entitlement validation delays, submitting unauthorized returns before verification completes.
Bruviti's platform analyzes telemetry streams from fab equipment to validate warranty claims against known failure signatures before authorizing returns. The AI correlates claim descriptions with sensor data patterns, recipe drift indicators, and historical failure modes specific to lithography, etch, and deposition tools. When a claim arrives, the platform instantly retrieves the tool's telemetry history, compares reported symptoms against actual performance signatures, and flags discrepancies that indicate operator error or environmental causes rather than equipment defects.
For semiconductor OEMs, this pre-return validation eliminates refurbishment waste while protecting warranty reserves. The platform learns from every validated claim, continuously refining detection models to catch emerging fraud patterns and operator-induced failures. Integration with existing warranty systems happens through standard APIs, enabling automated claim adjudication without replacing entitlement infrastructure. Claims processing accelerates from days to minutes, reducing customer friction while dramatically cutting NFF rates.
AI analyzes microscopic images from semiconductor failure analysis labs to identify nanometer-scale defects, classify failure modes, and validate warranty claims with forensic precision.
Automatically classifies and codes warranty claims for lithography, etch, and deposition tools, accelerating adjudication while ensuring consistent application of coverage terms.
Semiconductor warranty returns require specialized validation because tool telemetry reveals failure signatures that manual review cannot detect. EUV lithography systems generate terabytes of sensor data per production run. AI models trained on this telemetry distinguish legitimate equipment failures from recipe optimization attempts, operator errors, and environmental contamination. When a fab submits a warranty claim for chamber performance degradation, the platform correlates reported symptoms with consumable wear patterns, gas flow anomalies, and temperature excursions recorded in the tool's sensor logs.
For OEMs serving multiple fabs, cross-installation pattern detection identifies systemic issues versus site-specific problems. A claim trend across three fabs running identical recipes may indicate a design flaw warranting proactive replacement. The same symptoms isolated to one site suggest operator training gaps or environmental factors outside warranty coverage. This distinction protects warranty reserves while enabling data-driven decisions about field upgrades and process interventions.
High NFF rates result from three factors: inadequate pre-return diagnostics that miss operator-induced failures, manual claim review that cannot process telemetry at fab scale, and fraudulent claims that exploit validation delays. Without AI analysis of sensor data, fab engineers cannot distinguish equipment defects from recipe optimization side effects or environmental contamination before authorizing expensive returns.
The platform validates claims in minutes by instantly correlating reported symptoms with telemetry signatures from the specific tool. Legitimate failures match known sensor patterns and trigger automatic approval. Suspected NFF cases flag for human review with supporting telemetry evidence. This accelerates valid claims while protecting against invalid returns, reducing overall cycle time despite added validation.
The platform ingests standard fab telemetry including chamber sensor logs, recipe parameters, consumable usage metrics, and fault history. For lithography systems this includes exposure dose uniformity, reticle alignment data, and environmental controls. For etch and deposition tools it analyzes gas flow rates, RF power stability, and temperature profiles. Data arrives via existing FDC systems or direct tool interfaces.
Bruviti's AI identifies new fraud patterns within days by analyzing claim submissions across all connected fabs. The platform flags anomalies like identical failure descriptions from multiple sites, claims submitted immediately after warranty expiration warnings, or symptom reports inconsistent with telemetry evidence. Detection models update continuously as fraud tactics evolve.
Semiconductor OEMs typically improve warranty reserve accuracy by 35-50% within six months. AI-validated claim data provides actuarial models with cleaner inputs, distinguishing true failure rates from NFF noise. This enables tighter reserve brackets, releasing overcapitalized funds while maintaining coverage confidence. Finance teams gain real-time visibility into claim patterns affecting future reserve requirements.
