Abstract

The embodiment of the invention discloses a novel electrostatic protection method. The method comprises the following steps that an integrated circuit is arranged on a first chip; an electrostatic protection circuit is arranged on a second chip, and the electrostatic protection circuit comprises a first input output port, a second input contact port, a first diode, a first resistor, a first N-type field effect transistor and a ground end output port, and further comprises a second diode, a capacitor and a second N-type field effect transistor; and the first input output port is connected with the input port of the integrated circuit, so that the electrostatic protection method can realize dual protection on the integrated circuit, and the reliability of the integrated circuit is effectively ensured. Moreover, the integrated circuit and the electrostatic protection circuit are arranged on different chips, thereby avoiding the electrostatic protection design on the chip where the integrated circuit is located, and solving a problem that the electrostatic protection design cannot be carried out because of the limitation of the substrate material of the chip where the integrated circuit is located. And the electrostatic protection of a novel material integrated circuit which is sensitive to static electricity can be realized.
