    Abstract: Various embodiments of the invention provide techniques to ensure a layout for an integrated circuit is split-able. In a method embodiment, a layout is generated in a customer site having a layout library as inputs wherein the library provides exemplary layouts that have been verified to be spit-able and that can be used and layouts that can cause conflicts to avoid. A real-time odd cycle checker is also provided in which the checker identifies in real time conflict areas and odd cycles as they arise during layout generation. To reduce memory usage layouts of various devices may be separated so that each individual layout or a small number of layouts, rather than a large layout for the whole application circuit, can be checked against conflicts. Once the layout is ready at the customer site, it is sent to the foundry site to be decomposed into two masks and taped-out. Other embodiments are also disclosed.

Otherwise, assigning the via to a second via mask, wherein the second via mask aligns with a second metal mask different from the first metal mask.

    Abstract: 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.
