ABSTRACT:
This invention provides an input protection device having, within a body of semiconductor material, parallel, doped regions providing an input circuit and a charge collection area for protecting against static electricity charges at the input stage of semiconductor devices, the device including a low resistance layer formed on the body overlying the input circuit which is connected to an input pad on the body. Shortening the input signal delay time is thus attained.
