ABSTRACT:
An installation for processing a semiconductor wafer includes a semiconductor fabrication device having a load port, on which an identity code that can be read optically or through an effective electromagnetic field is stored. A mobile device, for example, a container communicating with the load port or a vehicle for transporting such a container, contains a corresponding reader to determine the identifier. The configuration makes the flexible determination of position within a fabrication facility possible. Also provided is a method for operating the installation.
