A semiconductor device includes a substrate; an inter layer dielectric disposed on the substrate; a TSV penetrating the substrate and the ILD. In addition, a plurality of shallow trench isolations (STI) is disposed in the substrate, and a shield ring is disposed in the ILD surrounding the TSV on the STI. During the process of forming the TSV, the contact ring can protect adjacent components from metal contamination.
