Traceability and Lot Tracking in Semiconductor

Written by Chandan Gaur | Oct 3, 2025 10:30:11 AM

Executive Summary 

Semiconductor manufacturing enterprises operate in a highly competitive, precision-driven environment where quality management, traceability, and regulatory compliance are of paramount importance. One such enterprise faced challenges in wafer tracking and lot traceability across multiple fab and test stages. Manual processes, fragmented systems, and delayed reporting hindered their ability to quickly analyse failures, enforce quality controls, and meet compliance standards. 

To address this, the enterprise deployed Agentic AI solutions within a context-first agentic infrastructure. Agent labels logs every wafer or batch movement in real-time. Agent search retrieves historical tracking and current production data, and Agent analysts analyse trends, deviations, and failures.  This solution provides end-to-end visibility, ensures regulatory compliance, and accelerates root-cause analysis, enabling operational efficiency and data-driven manufacturing. 

By implementing these agentic AI platforms, the organisation achieved digital traceability, reduced operational risks, improved audit readiness, and gained actionable insights into process optimisation and quality assurance. 

Customer Challenge 

Business Challenges 

The customer, a semiconductor manufacturer, struggled with fragmented lot tracking, manual reporting, and slow failure analysis. 

Key business problems included: 

  • Limited traceability: Wafer/batch history was siloed across fab and test systems. 

  • Delayed compliance reporting: Manual data aggregation slowed regulatory submissions. 

  • Slow failure analysis: Identifying root causes for defective wafers required significant time and manual effort. 

  • High operational risk: Incomplete traceability increases the risk of recalls or non-compliance.

Business goals: 

  • Ensure full traceability of each wafer/batch from start to finish. 

  • Accelerate failure analysis and quality control processes. 

  • Support regulatory compliance with auditable records. 

  • Improve workflow efficiency and data reliability across production systems. 

Existing solution limitations: 

  • Manual tracking is prone to errors. 

  • Disconnected logs across fab, test, and ERP systems. 

  • Limited ability to analyse historical trends or predict failure points. 

  • Time-consuming audit preparation. 

Technical Challenges 

Infrastructure and System Issues 

  • Multiple fab/test systems generating heterogeneous data. 

  • Disconnected databases with inconsistent logging formats. 

  • Manual aggregation of historical lot data. 

Integration and Data Management Issues 

  • No unified platform for batch/process step data. 
  • Poor integration between fab MES, test equipment, and ERP systems. 
  • Lack of centralised analytics and reporting capabilities. 

Scalability, Reliability, and Performance Limitations 

  • Existing systems were unable to track thousands of wafers in real-time. 

  • Slow queries and high latency during historical data retrieval. 

  • No real-time visibility into process deviations or batch anomalies. 

Security and Compliance 

  • No end-to-end audit trail for wafers/batches. 

  • Access to batch history is not role-controlled. 

  • Compliance reporting required extensive manual verification. 

Partner Solution 

Solution Overview 

The company implemented Agentlabel.ai, Agentsearch.ai, and Agentanalyst.ai to enable end-to-end traceability and lot tracking. 

  • Agent label: Logs wafers/batches at each fab and test step. 

  • Agent search: Retrieves historical and current batch data for inspection, audits, or analysis. 

  • Agent analyst: Analyses trends, identifies failures, and provides actionable insights for quality assurance. 

These agents work together to: 

  • Auto-log process steps and updates for every batch. 

  • Retrieve complete wafer/batch histories in seconds for audits or failure analysis. 

  • Analyse process deviations, defect trends, and potential compliance risks. 

  • Generate summary reports for management and regulatory purposes.
