Integrated circuit libraries include a first standard cell having a first left boundary and a first right boundary, and a second standard cell having a second left boundary and a second right boundary. The first standard cell and the second standard cell are of a same cell variant. A first active region in the first standard cell has a different length of diffusion than a second active region in the second standard cell. The first active region and the second active region are corresponding active regions represented by a same component of a same circuit diagram representing both the first standard cell and the second standard cell.

A method of designing a double patterning mask set for a layout of a chip includes designing standard cells. In each of the standard cells, all left-boundary patterns are assigned with one of a first indicator and a second indicator, and all right-boundary patterns are assigned with an additional one of the first indicator and the second indicator. The method further includes placing the standard cells in a row of the layout of the chip. Starting from one of the standard cells in the row, indicator changes to the standard cells are propagated throughout the row. All patterns in the standard cells having the first indicator are transferred to a first mask of the double patterning mask set. All patterns in the standard cells having the second indicator are transferred to a second mask of the double patterning mask set.
