Title:
VARIABLE-RESISTANCE ELEMENT USING AN ELECTROCHEMICAL REACTION, AND MANUFACTURING METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2011/071009
Kind Code:
A1
Abstract:
Provided is a structure for a variable-resistance element that uses an electrochemical reaction. Said structure limits the position at which metal cross-linking breaks to the position where it is preferable that said cross-linking breaks: namely, the part of an ion conduction layer closest to a first electrode. Also provided is a method for manufacturing the variable-resistance element. The variable-resistance element has a first electrode (11) which serves as a source for metal ions, a second electrode (12) which is less ionizable (i.e. has a higher redox potential) than the first electrode, and an ion conduction layer (23) which is interposed between the first and second electrodes and can conduct the metal ions. There is a first region in the ion conduction layer, adjacent to the first electrode, that has a diffusion coefficient that increases continuously towards the first electrode right up to the first electrode (fig. 6).
