Abstract:
A method for performing surface modeling of an integrated circuit substrate for the purpose of characterizing the integrated circuit substrate, comprising:initially dividing a representation of said integrated circuit substrate surface into a plurality of local partitions; thereafter forming divisions from said plurality of local partitions; positioning a representation of a first component at a first location on said representation of said integrated circuit substrate surface, thereby creating additional divisions within one of said plurality of local partitions; and if a number of divisions within said one of said plurality of local partitions exceeds a predefined value, promoting said one of said plurality of local partitions to a global partition and forming local partitions within said one of said plurality of local partitions; wherein forming divisions from said plurality of local partitions comprises applying an overgridding factor and an overgridding resolution, the overgridding factor defining a number of divisions to be created for each distance defined by the overgridding resolution.
