Abstract: A discrete tapering interconnection is disclosed that forms an interconnection between a first electronic circuit and a second electronic circuit within an integrated circuit. The discrete tapering interconnection includes a first set of multiple parallel conductors situated in a first metal layer of the metal layers of a semiconductor layer stack and a second set of multiple parallel conductors situated in a second metal layer of the metal layers of the semiconductor layer stack. The first set of multiple parallel conductors effectively taper the discrete tapering interconnection as the discrete tapering interconnection traverse between the first electronic circuit and/or the second electronic circuit. This tapering of the discrete tapering interconnection can be an asymmetric tapering or a symmetric tapering. The second set of multiple parallel conductors is arranged to form various interconnections between various parallel conductors from among the first set of multiple parallel conductors.

Abstract: In some embodiments, an initial circuit arrangement is provided. The initial circuit arrangement includes cells that include default-rule lines and non-default-rule lines. Line widths of the default-rule lines are selectively increased for a first cell in the initial circuit arrangement, thereby providing a first modified circuit arrangement. A first maximum capacitance value is calculated for the first cell of the first modified circuit arrangement. A second modified circuit arrangement is provided by selectively increasing line widths of the non-default-rule lines in the first modified circuit arrangement. A second maximum capacitance value is calculated for the first cell of the second modified circuit arrangement. A line width of a first non-default-rule line is selectively reduced based on whether the first maximum capacitance value adheres to a predetermined relationship with the second maximum capacitance value. The second modified circuit arrangement is manufactured on a semiconductor substrate.
