Abstract
A structure and method for performing a capacitance extraction on an integrated circuit, includes determining a parallel-plate capacitance between devices on different levels within the integrated circuit, adding extension shapes around each of the devices, reducing an area of overlapping extension shapes, multiplying a remaining area of the extension shapes by a constant to produce a fringe capacitance; and summing the parallel-plate capacitance and the fringe capacitance.
