Protective circuit for electrostatic discharge and method for manufacturing the same

Abstract

The present invention provides an electrostatic discharge protection circuit and its preparing method. The electrostatic discharge protection circuit includes a silicon substrate, an iron film, a nano-carbon tube layer and a transparent cover, the iron film and the nano-carbon tube layer are overlapped on the surface of the silicon substrate in turns, the transparent cover contains the iron film and the nano-carbon tube layer, and sealed with the silicon substrate, the inner surface of the transparent cover is coated with phosphor.

Description

technical field [0001] The invention relates to an electrostatic discharge protection circuit and a manufacturing method thereof. Background technique [0002] Electrostatic discharge (Electro Static Discharge, ESD) is the main factor that causes most electronic components or electronic systems to be damaged by electrical overstress (Electrical Overstress, EOS). Electrostatic discharge may cause permanent damage to semiconductor components, etc., thus affecting the circuit function of integrated circuits and making electronic products work abnormally. The generation of electrostatic discharge generally lies in the accumulation of static electricity in the human body, instruments or storage equipment during the manufacturing, production, assembly, testing, storage or handling of electronic components or systems, and even the electronic components themselves will have static electricity accumulation . When the human body, instruments or storage equipment come into contact wi...
