Abstract

The invention provides a thin film material for overvoltage protection of input and output pins of integrated circuits and a using method. The thin film material is a compound formed by five elements:60-90% of silicon, 35-5% of selenium, and the balance of nitrogen, germanium and arsenic; and the thin film material can be prefabricated into an alloy target through ion vapor deposition, and has athickness between 10 nm and 10 um. The using method is a low-cost strong inhibitor device design scheme for making the thin film material at pin areas of integrated circuits in a form of an overvoltage protection tape or an overvoltage protection ring, so as to prevent lightning and static impact for all the pins. By utilizing a specific threshold value breakover characteristic of the compound material, overvoltage protection is realized, so that the thin film material is novel in concept and simple in structure, and is an overvoltage protection material and device with extremely high overvoltage protection response speed and extremely strong overvoltage inhibition ability.

Description

technical field [0001] The invention relates to the field of overvoltage protection in circuits, in particular to a compound film overvoltage protection material and device used in integrated circuits. Background technique [0002] In today's information age, computer networks and communication equipment are becoming more and more sophisticated, and the requirements for their working environment are also getting higher and higher, and lightning and instantaneous overvoltage of large electrical equipment will be sent and received more and more frequently through power supplies, antennas, and radio signals. Equipment and other lines intrude into indoor electrical equipment and network equipment, causing damage to equipment or components, casualties, interference or loss of transmitted or stored data, and even misoperation or temporary paralysis of electronic equipment, system pause, data transmission interruption, LAN Even the wide area network is damaged. Overvoltage protect...
