    摘要: The embodiments of via mask splitting methods for double patterning technology described enable via patterning to align to a metal layer underneath or overlying to reduce overlay error and to increase via landing. If adjacent vias violate the G0-mask-split-rule for space or pitch (or both) between vias, the mask assignment of end vias are given higher priority to ensure good landing of end vias, since they are at higher risk of mislanding. The metal correlated via mask splitting methods enable better via performance, such as lower via resistance, and higher via yield.

    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.
