    Abstract: AUTOMATED INTEGRATED CIRCUIT MANUFACTURING SYSTEM A computer controlled manufacturing system for fabricating semiconductor wafers into large scale integrated circuit devices and wherein each semiconductor wafer has scored, or recorded thereon, distinct identifying indicia, such as a machine readable serial number. A plurality of concurrently operable semiconductor wafer processing stations are independently computer controlled. Each of the stations performing at least one discrete fabrication step. A digital computer system operable under stored program control means, said computer system being interconnected with and controlling said processing stations, random access storage means, reading means and conveying means, whereby under computer control selected ones of said semiconductor wafers which are randomly stored in said random access storage means may be selected and fabricated into first part number large scale integrated circuit devices, and selected second ones of said semiconductor wafers randomly stored in said random access storage means may be selected and fabricated into second part number large scale integrated circuit devices, where said first and second part number devices are not identical.
