PROBLEM TO BE SOLVED: To materialize the rise of the manufacture efficiency of an LSI or the reduction of manufacture cost, by integrating and utilizing the information about both design division and a manufacture division. SOLUTION: A computer unit (60) receives the input of the element property information of a semiconductor element from manufacture divisions (10-12) and also receives the input of design information of a semiconductor integrated circuit from manufacturing divisions (13-16) via a network, and creates the response information requested by a request source concerned, based on the above input information, in response to the request from the supply source of the above design information, and returns the created response information to the above request source. For example, the response information is the forecast yield information, at the time of having supposed that the semiconductor integrated circuit is constituted, making use of the element specified by the element property information. Hereby, the design division can be previously informed of the yield of products at the time of having placed an order with the manufacture division with products, and it becomes possible to properly select the manufacture division. The enhancement of the manufacture efficiency of LSI or the reduction of manufacture cost can be materialized by using the properly selected manufacture division.
