Abstract:
1. A method comprising: identifying a modular resistance-capacitance (RC) structure from a plurality of metal schemes wherein the modular RC structure has an interconnect configuration similar to interconnect configurations of the plurality of metal schemes; calculating, using a processor, one or more capacitance values of the modular RC structure by using a field solver; calculating, using a processor, a first equivalent dielectric constant and a first equivalent height of the modular RC structure based upon a variety of interconnect layers not having interconnects; calculating, using a processor, a second equivalent dielectric constant and a second equivalent height for each of the plurality of metal schemes; determining, using a processor, differences between the first and second equivalent dielectric constants and the first and second equivalent heights; deriving, using a processor, capacitance values of each of the plurality of metal schemes from the capacitance values of the modular RC structure and from the differences between the first and second equivalent dielectric constants and the first and second equivalent heights; and storing the derived capacitance values in a computer-readable memory.
