Abstract
A semiconductor device structure is provided. The semiconductor device structure includes a semiconductor substrate and a gate disposed on the semiconductor substrate. The semiconductor device structure also includes a source doped region and a drain doped region on two opposite sides of the gate. The semiconductor device structure further includes a source protective circuit and a drain protective circuit. From a side perspective view, a first drain conductive element of the source protective circuit partially overlaps a first source conductive element of the drain protective circuit.
