Integrated circuits including standard cells and methods of manufacturing the integrated circuits

An integrated circuit comprising a plurality of standard cells, the integrated circuit comprising:

• a plurality of active region pairs, each active region pair comprising, a first active region of a first conductive type and a second active region of a second conductive type extending in a first horizontal direction, wherein the first active region and the second active region of each active region pair are adjacent to each other;
• and
• a plurality of gate lines extending in a second horizontal direction that is orthogonal to the first horizontal direction,
• wherein the plurality of active region pairs comprises a first active region pair and a second active region pair arranged adjacent to each other such that a distance between the first and second active region pairs is greater than a distance between the first active region and the second active region in the first active region pair.

An integrated circuit comprising a plurality of standard cells aligned in a plurality of rows, the integrated circuit comprising:

• first and second active regions extending in a first horizontal direction in a first row;
• and
• third and fourth active regions extending in the first horizontal direction in a second row adjacent to the first row,
• wherein the second active region and the third active region are adjacent to each other, and wherein a distance between the second active region and the third active region is greater than a distance between the first and second active regions, and greater than a distance between the third and fourth active regions.
