WaferGuard™ – Precision Wafer Transport Data Logger

Protecting Semiconductor Wafers from Origin to Destination

WaferGuard™ is the industry’s most advanced non–real-time wafer transport monitoring solution. Designed to fit seamlessly inside a standard 300mm or 200mm wafer cassette or FOUP, WaferGuard™ records critical environmental and handling conditions throughout the shipping process. At the destination, simply connect the device to download a complete journey report, helping you safeguard yield, ensure compliance, and optimize shipping processes.

By providing a complete digital report at the shipment’s final destination, WaferGuard™ helps chip manufacturers, logistics providers, and quality managers analyze transport conditions, optimize shipping routes and practices, and reduce costs from damage or delays.

Key Benefits

  • Improve Yield & Reduce Loss – Identify transit events that can cause wafer damage before they impact production.
  • Comprehensive Monitoring – Records temperature, humidity, vibration, tilt, light, and pressure.
  • Seamless Fit – Designed with wafer-like dimensions to fit securely inside standard FOUPs and wafer cassettes.
  • Data-Driven Decisions and Traceability – Post-trip analytics provide insight into handling practices and route conditions.
  • Reusable & Cost-Efficient – Rugged, wafer-shaped design supports shipment along real semiconductor wafers.
  • Efficiency – Battery powered with automatic reset for continuous reuse for future shipments.

How it Works

  • Load WaferGuard™ into a standard wafer cassette or FOUP alongside your wafers.
  • Ship as normal—WaferGuard™ records conditions continuously throughout transit.
  • Download the full trip report and raw log file at the destination in CSV format.
  • Analyze & Optimize – Identify risks, improve packaging, and optimize for best logistics routes.

Applications

  • Front-End Wafers – Protect sensitive, high-value wafers during long-distance shipment.
  • Back-End Process Wafers – Verify safe transport of processed wafers before packaging.
  • Tool Relocation & Installations – Ensure wafer handling safety during equipment moves.

Why Choose WaferGuard™?

LUMI Sensors’ WaferGuard™ is not just a data logger, it’s a critical quality assurance tool. By identifying and documenting every environmental and handling stress event during transport, you can reduce costly wafer loss, streamline your supply chain, and maintain your competitive edge in semiconductor manufacturing.
