A semiconductor device includes a substrate, a power device, a protection circuit, a dielectric layer, a drain pad, a source pad, and a gate pad. The power device and the protection circuit are disposed on the substrate. The power device includes a drain electrode, a source electrode, and a gate electrode. The protection circuit has a first terminal electrically connected with the source pad and asecond terminal electrically connected with the gate pad. The dielectric layer is disposed on the power device and the protection circuit. The drain pad, the source pad, and the gate pad are disposedon the dielectric layer and respectively electrically connected with the drain electrode, the source electrode, and the gate electrode. At least part of the protection circuit is disposed under the source pad, the gate pad, or the drain pad. The semiconductor device does not waste layout area, and maintains small layout area.
