Silicon chip manufacturer TowerJazz not only produces high-memory radio frequency identification chips, but is now employing Wi-Fi-based RFID technology at one of its own fabrication facilities to track work-in-progress. The solution consists of battery-powered Wi-Fi tags on batches of wafers, exciters to pinpoint a tag’s location, and software to determine at which workstation or on which rack wafers are located during manufacturing. The location data is forwarded to the company’s dispatch software, which then updates the lot’s status. At any time during manufacturing, the firm can review the physical location history for each lot in the process of being manufactured. Learn how accurate, real-time RFID data improved efficiencies and increased on-time delivery.
