Abstract
PURPOSE:To prevent fusion of electrode wirings by providing a current limiting resistance before the diffusion resistance of a gate protecting device. CONSTITUTION:A MOS type transistor 20 and a gate protecting device 30 are formed in the same substrate 21. The gate protecting device 30 formed the diffusion region 31 of N type having been simultaneously formed with source and drain as well as impurity concentration regulating regions 33', 33'' and is constituted by the Gl wiring 35 form the gate electrode 29 of the transistor 20 and the Al wiring 34 to input. The ohmic contact resistance between the Al wirings 34, 35 is suitably selected by regulating the impurity concentrations of the regions 33', 33'' and since this results in the form that an ohmic contact resistance 33R' has been inserted before the protection diode 33D, overcurrent may be limited.
