Abstract:
1. A system of carrier transport traffic management, comprising: a fabrication tool; a host computer, connected to the fabrication tool, configured to acquire an available capacity of control jobs, process jobs or internal buffer sections for the fabrication tool upon detecting a loadport of the fabrication tool is available; and a material transport system, connected to the host computer, configured to receive the available capacity of the control jobs, process jobs or internal buffer sections corresponding to the fabrication tool, acquire a carrier identity corresponding to a carrier, acquire a required capacity of the control jobs, process jobs or internal buffer sections corresponding to the carrier, and issue a load command to the transport system to transport the carrier to the fabrication tool if the available capacity of the control jobs, process jobs or internal buffer sections exceeds or equals to the required capacity of the control jobs, process jobs or internal buffer sections.
