Patent ID: 8219375

Claim:
A computer readable recording medium that stores therein executable instructions of a plated film thickness calculating program which when executed on a computer perform simulation of a semiconductor integrated circuit producing process in which a plating treatment for plating a surface of a substrate having a plurality of plateaus and grooves with a conductor, a polishing treatment for polishing the plated conductor until a part of the plateaus appears and an over-polishing treatment for polishing until the plated conductor in the plurality of grooves is separated are performed, the executable instructions of the plated film thickness calculating program performing a process comprising: simulating the plating treatment of plating the surface of the substrate with the conductor for a given thickness of the conductor to calculate the thickness distribution of the conductor over the plateaus and grooves; calculating a thickness of the conductor to be removed by the polishing treatment until at least a part of the plateaus appears; calculating a remaining maximum thickness of the conductor on any part of the plateaus after performing the polishing treatment; and repeating the simulating to calculate the thickness distribution, the thickness to be removed calculation and the remaining maximum thickness calculation by changing the given thickness until a minimum of the given thickness is determined in which the remaining maximum thickness of the conductor becomes less than a predetermined level.
