ABSTRACT:
A protection circuit using point discharge suitable for use in an integrated circuit, protects circuit from damage by electrostatic discharge. The integrated circuit at least comprises an input/output port, a high voltage line, and a low voltage line. The protection circuit has point discharge structures at two ends of the input/output ports, respectively corresponding to the point discharge structures of the high and low voltage lines, and is suitable for use in all semiconductor fabricating processes.
