A gate structure of a semiconductor memory device capable of preventing a poly void generation by forming a hard mask and maintaining a hysteresis area within a certain value. By reading ID from the portable information terminal, the notebook PC is able to identify a network address of the portable information terminal so as to establish a network connection with the portable information terminal. The package is published to an intermediate holding area. The volumetric change of the sensing element causes the deflectable arm to deflect. The adhesive complex coacervates described herein exhibit good interfacial tension in water when applied to a substrate. As a result, the cross-sections of the veins in that region are not reduced, but are maintained such that the circulation of the blood is not impeded, significantly reducing the risk of thrombosis.
