A semiconductor integrated circuit device may include a target PMOS transistor, a target NMOS transistor, a first stress-applying circuit, a second stress-applying circuit, a third stress-applying circuit and a fourth stress-applying circuit. An inverter may include the target PMOS transistor and the NMOS transistor. The first stress-applying circuit may be configured to apply a first DC level to a gate of the target PMOS transistor. The second stress-applying circuit may be configured to apply a second DC level to a gate of the target NMOS transistor. The third stress-applying circuit may be configured to apply an AC voltage shape to the gate of the target NMOS transistor. The fourth stress-applying circuit may be configured to apply the AC voltage to a drain of the target NMOS transistor.
