SENTINEL CUSTOM SOLUTIONS
SILICON WAFER TRACKING

Customer Need

To automatically ID and track silicon wafer carrying caddies in the clean room environment from inception to finished wafer. RFID system and tags must withstand severe temperature/humidity cycling, chemicals, shock/vibration and other RF/EMI interferences.

Sentinel Custom Solution

Sentinel Silicon Wafer Tracking Solution

* 134 kHz, MicroReader module
* Glass encapsulated tags
* 6" flexible directional stick antenna
* Crypto key & random number algorithms
* Programming software for on-the-fly writing of tags
* Embedded tag FOUP and probe-card ID options
* CAN interfaces/DLLs/APIs
* Pentium Win-9X servers
* Embedded firmware and auto-cycling software
* Integrated temperature sensor in tag
* Out-of-range parameter control features/alarms
* Tag data-lock for audit trail, QC trials

System Performance Benchmarks

* Ultra-rugged tag packaging for high-temperatures, chemical and gas wash environments
* Remote system tuning for read range, write range & read/write/lock cycling control
* 125 degrees C resistant tags, antennas and reader modules (totally sealed system)
* Enhanced wafer lot tracking for full process control and yield improvements
* < 15 month system payback/ROI

Other Potential Applications

* Tire ID and tracking (in-process/in-use in auto)
* Heat-treated parts ID and tracking
* "In-situ-sterilized" medical parts, tools and reusable supplies tracking
