  • Patent number: 8572537
    Abstract: A system and method for extracting the parasitic contact/via capacitance in an integrated circuit are provided. Parasitic extraction using this system can lead to an improved accuracy on contact/via parasitic capacitance extraction by taking into account of the actual contact/via shape and size variation. The common feature of the various embodiments includes the step of generating a technology file, in which the contact/via capacitance in the capacitance table is derived from an effective contact/via width table. Each element of the effective contact/via width table is calibrated to have a parasitic capacitance matching to that of an actual contact/via configuration occurring in an IC.

  • Publication number: 20130275927
    Abstract: 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.

    Abstract: A method of generating a bias-adjusted layout design of a conductive feature includes receiving a layout design of the conductive feature. If a geometry configuration of the layout design is within a first set of predetermined criteria, the bias-adjusted layout design of the conductive feature is generated according to a first layout bias rule. If the geometry configuration of the layout design is within a second set of predetermined criteria, the bias-adjusted layout design of the conductive feature is generated according to a second layout bias rule.

  • Publication number: 20130139121
    Abstract: The present disclosure relates to methods and apparatuses for generating a through-silicon via (TSV) model for RC extraction that accurately models an interposer substrate comprising one or more TSVs. In some embodiments, a method is performed by generating an interposer wafer model having a sub-circuit that models a TSV. The sub-circuit can compensate for limitations in resistive and capacitive extraction of traditional TSV models performed by EDA tools. In some embodiments, the sub-circuit is coupled to a floating common node of the model. The floating common node enables the interposer wafer model to take into consideration capacitive coupling within the interposer. The improved interposer wafer model enables accurate RC extraction of an interposer with one or more TSVs, thereby providing for an interposer wafer model that is consistent between GDS and APR flows.
