A mass-production transfer support system has a mass-production transfer source managing computer for managing information generated in a trial-production process of a semiconductor device and a mass-production transfer destination managing computer for managing a mass-production process of the semiconductor device. The mass-production transfer source managing computer comprises: quality/recipe information input accepting means; quality/recipe information sending means; apparatus-difference correction information input accepting means for accepting an input of apparatus-difference correction information for correcting a difference in the quality of the semiconductor device associated with an apparatus-difference between semiconductor manufacturing apparatuses; apparatus-difference correction information storing means; and apparatus-difference correction information providing means for storing the apparatus-difference correction information in a database accessible by the mass-production transfer destination managing computer.
