Integrated circuits including active patterns with various widths and methods of designing the integrated circuits

An integrated circuit comprising:

• a plurality of first cells in a first row that extends in a first direction;
• and
• a plurality of second cells in a second row that extends in the first direction,
• wherein the plurality of first cells comprise respective ones of a plurality of first active patterns extending in the first direction,
• wherein the plurality of second cells comprise respective ones of a plurality of second active patterns extending in the first direction,
• wherein ones of the plurality of first active patterns have different widths in a second direction that is perpendicular to the first direction, and
• wherein ones of the plurality of second active patterns each have a first width in the second direction.

A method of manufacturing an integrated circuit comprising a plurality of cells, the method comprising:

• obtaining a netlist defining the plurality of cells;
• and
• placing the plurality of cells in a plurality of rows that extend in a first direction based on the netlist,
• wherein the placing the plurality of cells comprises:
• placing a first cell and a second cell in a first row among the plurality of rows to be adjacent to each other;
• and
• placing a third cell and a fourth cell in a second row among the plurality of rows to be adjacent to each other,
• wherein the first cell and the second cell respectively comprise a first active pattern and a second active pattern, the first active pattern and the second active pattern extending in the first direction,
• wherein the third cell and the fourth cell respectively comprise a third active pattern and a fourth active pattern, the third active pattern and the fourth active pattern extending in the first direction,
• wherein the first active pattern and the second active pattern respectively have different widths in a second direction that is perpendicular to the first direction, and
• wherein each of the third active pattern and the fourth active pattern has a first width in the second direction.
