Abstract
A semiconductor device includes a substrate and a plurality of fin structures. A first fin structure and a second fin structure are spaced at a distance D. A first dummy fin structure is adjacent to the first fin structure, and a second dummy fin structure is adjacent to the second fin structure. The device further includes an isolation layer over the substrate and the first and second dummy fin structures, and surrounding the first and second fin structures. The fin structures are arranged such that a distance Dbetween the first fin structure and the first dummy fin structure is greater than the distance D
