摘要： An electrostatic discharge (ESD) protection circuit protects a gate oxide of elements in an internal circuit against ESD. During an ESD test, if the sum of driving voltages of ESD protectors connected between a power pad and a ground pad is higher than the gate oxide breakdown voltage of elements in the internal circuit, the structure of the ESD protector is changed or another ESD protector is additionally provided so as to protect the gate oxide of the elements in the internal circuit against ESD.

摘要： An electrostatic discharge protection circuit protects the internal circuits of a semiconductor. The electrostatic discharge protection circuit includes a first electrostatic protection unit connected to a power source supply pad. The first electrostatic protection unit discharges an ESD current into the power source supply pad when an ESD is introduced into the input/output pad, and generates a first driving voltage by utilizing the ESD current flow through a voltage-drop unit. A driver driven by the first driving voltage generates a second driving voltage by an ESD current. A second electrostatic protection unit discharges the introduced ESD current into the power source supply pad by the second driving voltage such that a voltage applied to a gate of the first NMOS transistor is reduced.

摘要： A device to protect a semiconductor device from electrostatic discharge is disclosed. In order to protect an internal circuit from electrostatic discharge, the semiconductor electrostatic protection device includes a transfer unit for transferring static electricity inputted to an input/output terminal to a first power line. A driving unit is also included for outputting a driving voltage corresponding to a potential difference between the input/output terminal and the first power line. Finally, a discharge unit for discharging the static electricity inputted to the input/output terminal to a second power line by way of the driving voltage is provided. The semiconductor electrostatic protection device prevents damage to an internal circuit due to the voltage drop of an intermediate medium by reducing the intermediate medium on a static electricity discharge path.
