A semiconductor fabrication enterprise includes fabrication equipment,
transportable containers for work--in--process and an enterprise
information system. The transportable containers have associated radio
frequency tags having identification codes uniquely identifying the
carriers in the fabrication process. The enterprise information system
contains data corresponding to each such identification code. The
identification codes are read by a radio frequency interrogation device,
and the radio frequency interrogation device carries out transactions
with the enterprise data system to transfer the data corresponding to the
identification codes to the radio frequency interrogation device. The
radio frequency tags may be adapted for read/write functionality allowing
for writing data to the radio frequency tags and synchronization of radio
frequency tag data and enterprise information system data.
