Root Cause Investigations for Semiconductor & Electronics Quality
When a lot fails final test or a customer return lands on your desk, your team needs to trace the failure across process, equipment, and materials—fast.
The Cost of Traditional Investigations
The Problem
- Semiconductor fabrication generates enormous volumes of segmented process data.
- Production handles constant quality escapes: lots failing final test, 8Ds, and holds.
- The challenge is connecting disparate systems (MES, SPC, maintenance logs).
The Impact
- Teams manually pull cross-reference timestamps in spreadsheets.
- Complex failures span obscure interactions between recipes, tooling, and materials.
- Manual analytical approaches are slow and produce incomplete causal chains.
Lattice Root Cause
- Lattice auto-indexes evidence across all your factory systems out-of-the-box.
- Agentic AI traverses engineering data to build structured causal analyses.
- Eliminates weeks of manual data joining and narrative drafting.
Core Investigations
Systems designed to handle the highest stakes in the semiconductor & electronics industry.
Customer Return / 8D Investigations
Structured failure analysis for customer-reported defects, with full traceability from return data to manufacturing history.
Lot Failure & Yield Excursion Investigations
Investigate why a lot failed final test or yield dropped, tracing across process steps, equipment, and materials.
Process Excursion Root Cause
When SPC flags an out-of-control process, investigate the causal chain across equipment, recipe, and environmental factors.
Incoming Material Investigations
Investigate whether incoming wafer, substrate, or component quality issues are causing downstream failures.
Reliability & Qualification Failures
Investigate failures during qualification, burn-in, or reliability testing, connecting to process and materials data.
Assembly & Packaging Failure Analysis
Investigate defects in die attach, wire bond, encapsulation, or other back-end processes.
Produce Investigations That
Hold Up Under Scrutiny
Lattice helps quality teams produce comprehensive, defensible investigations. Faster than manual methods and more rigorous than ad-hoc processes.
