Abstract:
A process control method for a semiconductor device fabrication line, using a lot-base management host computer that performs management for each lot by managing a process condition for each lot, a correspondence between a carrier ID and a lot ID, and a correspondence between a slot ID and a wafer ID in each lot; a wafer-base management host computer that performs management for each wafer in a lot by managing a process condition corresponding to a wafer number in a lot; and a converted condition instructing section that transmits data acquired from the lot-base management host computer and the wafer-base management host computer to a semiconductor fabrication apparatus,said method comprising the steps of: inquiring to the converted condition instructing section about lot information based on the ID of a carrier loaded into the semiconductor fabrication apparatus; and acquiring from the converted condition instructing section a process condition for the lot, slot ID information and wafer ID information from the lot-base management host computer, and in a case where wafers in process are experimental wafers, not only acquiring information of each wafer in the lot from the wafer-base management host computer, but also transmitting a process condition corresponding to the slot ID to the semiconductor fabrication apparatus.
