Abstract
Various examples of integrated circuit layouts with line-end extensions are disclosed herein. In an example, a method includes receiving an integrated circuit layout that contains: a first and second set of shapes extending in parallel in a first direction, wherein a pitch of the first set of shapes is different from a pitch of the second set of shapes. A cross-member shape is inserted into the integrated circuit layout that extends in a second direction perpendicular to the first direction, and a set of line-end extensions is inserted into the integrated circuit layout that extend from each shape of the first set of shapes and the second set of shapes to the cross-member shape. The integrated circuit layout containing the first set of shapes, the second set of shapes, the cross-member shape, and the set of line-end extensions is provided for fabricating an integrated circuit.
