A semiconductor production system has storage devices for storage of all kinds of information including, but not limited to, the information concerning semiconductor design and information as to semiconductor manufacture along with information relating to semiconductor inspection processes, while representing as a class an instance added with meta data indicative of the role of the information in accordance with a logical expressive form. The system has a network for the storage device use, called the storage area network or “SAN”. The SAN is for interconnection between respective ones of the storage devices, semiconductor manufacturing apparatuses and a semiconductor inspection apparatus. The storage devices are seamlessly accessible from any one of the semiconductor manufacture apparatuses and the semiconductor inspection apparatus and also from a semiconductor design environment associated therewith.
