Abstract: A semiconductor device includes a fin-shaped structure on a substrate, a single diffusion break (SDB) structure in the fin-shaped structure to divide the fin-shaped structure into a first portion and a second portion, and a gate structure on the SDB structure. Preferably, the SDB structure includes silicon oxycarbonitride (SiOCN), a concentration portion of oxygen in SiOCN is between 30% to 60%, and the gate structure includes a metal gate having a n-type work function metal layer or a p-type work function metal layer.
