    摘要: An interconnect structure including a bottom layer over a substrate, where the bottom layer includes at least one bottom layer line and at least one bottom layer via. The interconnect structure further includes a transition layer over the bottom layer, where the transition layer includes at least one transition layer line and at least one transition layer via. The interconnect structure further includes a top layer over the transition layer, where the top layer includes at least one top layer line and at least one top layer via. The at least one transition layer via has a cross sectional area at least 30% less than a cross sectional area of the at least one top layer via.

    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.
