Integrated circuit including multiple height cell and method of fabricating the integrated circuit

An integrated circuit comprising:

• a first cell in a first row extending in a first horizontal direction;
• a second cell in a second row extending in the first horizontal direction adjacent to the first row;
• and
• a third cell continuously extending in the first row and the second row,
• wherein the third cell comprises a first active region of a first conductivity type and a second active region of a second conductivity type extending parallel to each other in the first horizontal direction,
• wherein the first active region comprises at least a portion thereof in the first row, and the second active region comprises at least a portion thereof in the second row.

An integrated circuit comprising:

• a single height cell in a first row extending in a first horizontal direction, the single height cell comprising a first active region of a first conductivity type extending in the first horizontal direction;
• and
• a multiple height cell continuously extending in the first row and in a second row that extends in the first horizontal direction adjacent to the first row, the multiple height cell comprising a second active region of a second conductivity type extending in the first horizontal direction,
• wherein the first active region comprises a portion thereof facing the second active region in the first horizontal direction.
