Abstract:
1. A computer-implemented creation method for database relating to a plurality of semiconductor integrated circuits, the database registering, for the semiconductor integrated circuits, a plurality of function block cells constituting a design data of the corresponding semiconductor integrated circuit and a plurality of evaluation values corresponding to the plurality of function block cells, such that the plurality of function block cells are associated with the plurality of evaluation values, the creation method comprising: judging, by a computer, whether a plurality of function block cells constituting design data of a desired semiconductor integrated circuit include an unregistered function block cell which is not registered in the database; calculating, by a computer, an unregistered evaluation value corresponding to the unregistered function block cell when the plurality of function block cells include the unregistered function block cell, the unregistered evaluation value including verification values of optical proximity effect correction (“OPC”) and process proximity correction (“PPC”) for a pattern corresponding to the unregistered function block cell, a critical area value for a pattern corresponding to the unregistered function block cell, and a probability that hot spot or failure portion causing reduction of yield is included in a pattern corresponding to the unregistered function block cell, wherein: the verification value of OPC or PPC corresponds to a difference between a cell shape after OPC or PPC and a reference cell shape, and the critical area value represents a size of an area in which a fatal defect occurs if particles are present; and updating, by a computer, the database by registering the unregistered function block cell and the unregistered evaluation value.
