| titleOfInvention | Method of making ESD protection circuit with three stages |
| abstract | An MOS electrostatic discharge, ESD, protection circuit for protecting semiconductors from ESD damage is formed on a doped silicon substrate. The circuit includes three stages. The first stage includes a first MOSFET transistor and a grounded region formed in the substrate. The first MOS transistor has a source/drain circuit connected between the first node and ground, and has a control gate electrode connected to ground. The second stage includes a string of MOSFET transistors connected in a series string. The transistors in the string are in sufficient number to provide a circuit which will conduct at a high current level to protect the output circuit from overvoltage when the voltage exceeds a critical value. The third stage includes a third stage MOSFET device with a control gate connected to the second stage output and to the output of the circuit. The source and drain circuit of the third stage device are connected between the third node and the ground connection. |
