Abstract
The integrated circuit (IC) structure includes a semiconductor substrate, a first active region, a dummy fill region, a second active region, first metal gate structures, and second metal gate structures. The first active region is on the semiconductor substrate. The dummy fill region is on the semiconductor substrate. The second active region is on the semiconductor substrate and spaced apart from the first active region by the dummy fill region. The first metal gate structures extend in the first active region and have a first gate pitch and a first gate width. The second metal gate structures extend in the second active region and have a second gate width greater than the first gate width and a second gate pitch being an integer times the first gate pitch, and the integer being two or more.
