    摘要: In a semiconductor device design method performed by at least one processor, first and second electrical components are extracted from a layout of a semiconductor device. The semiconductor device has a semiconductor substrate and the first and second electrical components in the semiconductor substrate. Parasitic parameters of a coupling in the semiconductor substrate between the first and second electrical components are extracted using a first tool. Intrinsic parameters of the first and second electrical components are extracted using a second tool different from the first tool. The extracted parasitic parameters and intrinsic parameters are combined into a model of the semiconductor device. The parasitic parameters of the coupling are extracted based on a model of the coupling included in the second tool.

    摘要: A method includes determining model parameters for forming an integrated circuit, and generating a techfile using the model parameters. The techfile includes at least two of a C_worst table, a C_best table, and a C_nominal table. The C_worst table stores greatest parasitic capacitances between layout patterns of the integrated circuit when lithography masks comprising the layout patterns shift relative to each other. The C_best table stores smallest parasitic capacitances between the layout patterns when the lithography masks shift relative to each other. The C_nominal table stores nominal parasitic capacitances between the layout patterns when the lithography masks do not shift relative to each other. The techfile is embodied on a tangible non-transitory storage medium.

    摘要: A method includes providing a layout of an integrated circuit design, and generating a plurality of double patterning decompositions from the layout, with each of the plurality of double patterning decompositions including patterns separated to a first mask and a second mask of a double patterning mask set. A maximum shift between the first and the second masks is determined, wherein the maximum shift is a maximum expected mask shift in a manufacturing process for implementing the layout on a wafer. For each of the plurality of double patterning decompositions, a worst-case performance value is simulated using mask shifts within a range defined by the maximum shift. The step of simulating the worst-case performance includes calculating capacitance values corresponding to mask shifts, and the capacitance values are calculated using a high-order equation or a piecewise equation.
