System of manufacturing semiconductor intergrated circuit

A system of manufacturing a semiconductor integrated circuit, comprising:

• a data-managing center comprising:
• a cost/number-of-days database containing data representing courses for manufacturing the semiconductor integrated circuit, each of which has attributes of costs and the number of days in fields of product types and urgency degrees of the semiconductor integrated circuit;
• a reservation status database containing data of an acceptable reservation quantity in fields of the product types and the urgency degrees of the semiconductor integrated circuit and in fields of chip-completion dates;
• and a design/manufacture status database containing data representing statuses of ordering, releasing, designing, and manufacturing in fields of a client;
• said data-managing center communicating wit said client to thereby perform data management;
• a designing center communicating with said client and performing designing of the semiconductor integrated circuit on the basis of release data from said client, to output layout data as a product of the designing;
• a manufacturing center which performs manufacturing of the semiconductor integrated circuit according to manufacture data that is released from one of said designing center and said client and that is intended for use in the manufacturing;
• wherein:
• said data-managing center, said designing center, and said manufacturing center are connected together via the Internet;
• and
• each of said centers uses information contained in said databases of said data-managing center, performs two-way communication with said client, and thereby progresses the production of the semiconductor integrated circuit.
