In semiconductor manufacturing, FOUPs and wafer cassettes continuously move through Automated Material Handling Systems (AMHS) between process tools, stockers, and workstations. Accurate identification of each carrier is essential to ensure correct routing, process control, and uninterrupted production flow.

A fixed mount code reader enables real-time reading of 1D and 2D codes on FOUPs and cassettes as they move through the AMHS network. It ensures reliable identification at transfer points such as load ports and stockers, allowing seamless communication with factory automation systems. This improves material flow accuracy, reduces handling errors, and supports stable semiconductor production operations.
