Method for adopting positive electronic corrosion-resistant to prepare metal nano electrode

Abstract

A method uses the positive electron anticorrosion agent to prepare metal nano electrode. The main features of the invention is to use the neighboring effect of electron band, use the EBL to gain a pair or a group of the positive electron anticorrosion agent groove figures that have line, hole and other various shapes at the space that is measured by nano on various underlay, and then use secondly the metal deposition and peel off technology to prepare various metal material nano electrode. The main procedures of which include coating the positive electron anticorrosion agent on the interlay; baking frontally; expose by direct electron band; develop; to fix; vaporize or sputtering metal; to peel off in the acetone. The distance between the metal nano electrode that is prepared by such method can be 30~100mm, is suitable to make various quanta component, nano line, nano tube component, single electronic component and various components or circuit. The method has many advantages, such as: less technology procedure, simple, stable and reliable, multiple uses and can be compatible with the traditional CMOS technology.

Description

technical field [0001] The invention belongs to the technical field of nano processing, in particular to a method for preparing a metal nano electrode. Background technique [0002] For more than half a century, semiconductor integrated circuits with CMOS as the mainstream technology have been developing rapidly following "Moore's Law".
