Patent ID: 6954907

Claim:
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 course having attributes of cost 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 status of ordering, releasing, designing, and manufacturing in fields of a client; said data-managing center communicating with 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 being connected together via the Internet; and each of said centers uses information contained in said databases of said data-managing center, performing two-way communication with said client, and thereby progressing the production of the semiconductor integrated circuit.
