Claim 0:
1. A semiconductor device, comprising:
a fin-shaped structure on a substrate;
a gate structure on the fin-shaped structure and an interlayer dielectric (ILD) layer around the gate structure;
a first spacer around and not directly under the gate structure;
a single diffusion break (SDB) structure in the ILD layer and the fin-shaped structure, wherein the SDB structure comprises:
a bottom portion; and
a top portion on the bottom portion, wherein the top portion and the bottom portion comprise different widths and a top surface of the bottom portion is higher than a top surface of the fin-shaped structure; and

a second spacer around the SDB structure, wherein the first spacer and the second spacer comprise same widths and different heights.
