B: Handling Process Identification - A semiconductor CIDRW reader reads the CID tag station information on the overhead crane track, monitors the crane's real-time position, and plans and dispatches routes based on its own location, ensuring safe operating distances and transport efficiency.

C: Cassette Storage Management - A semiconductor CIDRW reader, installed in an E-Rack or wafer cassette stocker, identifies the specific storage time, removal time, and storage location of a wafer cassette in real time. It can also quickly and accurately locate the storage location of the desired wafer cassette through the management system.
