ABSTRACT:
Disclosed is an electrostatic discharge (ESD) protecting circuit, capable of consuming a high voltage or overcurrent applied to a semiconductor circuit device and thereby protecting the circuit device from the instant ESD impact. The ESD protecting circuit according to this invention has only two wells and a highly doped region which brings an N-well into an electrical connection with the P-well. Accordingly, the present invention provides effects of reducing the area of the ESD protecting circuit and removing an instant ESD impact.
