Abstract: PURPOSE:To obtain a semiconductor device where an electrostatic breakdown strength of a MOS transistor is improved and an operation speed is not adversely affected by providing a resistor and a capacitor at a power supply wire of an input protection circuit. CONSTITUTION:An n-channel MOS transistor Q1 with an LDD structure is formed of a gate electrode 5 and diffusion layers 8 and 9. Also, an n-channel MOS transistor Q2 with the LDD structure is formed of a gate electrode 6 and the diffusion layers 9 and 10. On the other hand, for example a p<+>-type diffusion layer 11 and an n<+>-type diffusion layer 12 are formed within an activation region at different parts of MOS transistors Q1 and Q2. Then, a capacity c2 is formed of p<+>-n<+> junction consisting of the diffusion layers 11 and 12. The capacity c1 is formed of the p<+>-n<+> junction which is similar to a capacitor c2. Further, a resistor R consisting of, for example, a polycrystalline silicon film is formed on a field oxide film 3, thus enabling influence due to excessive voltage input to be suppressed.
