Continuous in-line tracking of wafer carriers is critical in semiconductor manufacturing to ensure accurate material flow, process control, and production efficiency. Wafer carriers such as FOUPs and cassettes move through multiple process stages, where misidentification or tracking loss can lead to process errors, yield loss, and downtime.

A fixed mount code reader enables real-time tracking of wafer carriers by reliably reading 1D and 2D codes during transport and handling. It ensures accurate identification at each process step, supporting automated material handling systems (AMHS) and improving overall production visibility. This enhances process reliability, reduces tracking errors, and supports efficient semiconductor manufacturing operations.
