PURPOSE:To prevent an input pad from being electrically connected to an output pad via a parasitic element of a substrate, and suppress crosstalks and noise induced via a pad. CONSTITUTION:An n<+> type diffused layer 6 is provided within a surface region of a p<-> type silicon substrate 1 under a pad 3 for use in an input pad. The diffused layer 6 is led out by an extraction electrode 7 formed on an insulated film 2, and connected to an alternating current ground point. |
