Abstract:
A semiconductor device manufacturing line for manufacturing a semiconductor device using a container accommodating a semiconductor wafer, comprising:a manufacturing apparatus for performing prescribed processing on a semiconductor wafer; a check apparatus for checking whether the processing performed on said semiconductor wafer by said manufacturing apparatus is appropriate; one container and another container for respectively accommodating a prescribed number of semiconductor wafers; a wafer transport apparatus configured for taking a prescribed semiconductor wafer determined as not being processed appropriately and requiring rework processing out of a prescribed number of said semiconductor wafers checked by said check apparatus and accommodated in said one container to transport said prescribed semiconductor wafer from one container into another container, and returning said prescribed semiconductor wafer transported into said another container and subjected to the rework processing, into said one container; a storage apparatus for storing said one container and said another container; a transfer apparatus for transferring said one container and said another container to said manufacturing apparatus, said check apparatus, said storage apparatus and said wafer transport apparatus; and a control apparatus for controlling operations of said manufacturing apparatus, said check apparatus, said storage apparatus, said wafer transport apparatus, and said transfer apparatus, wherein said control apparatus is configured for providing an instruction of storing said one container to said storage apparatus, specifying said prescribed semiconductor wafer based on a check result by said check apparatus of said semiconductor wafers accommodated in said one container and providing to said wafer transport apparatus an instruction of transporting said specified, prescribed semiconductor wafer into said another container, forming a rework lot for said another container into which said prescribed semiconductor wafer is transported, providing an instruction of performing rework processing on said prescribed semiconductor wafer to said manufacturing apparatus, providing to said wafer transport apparatus an instruction of returning said prescribed semiconductor wafer subjected to the rework processing and accommodated in said another container, into said one container, and regarding said rework lot as being completed after said prescribed semiconductor wafer is transported into said one container.
