Title:
SWITCHING ELEMENT AND METHOD FOR MANUFACTURING SWITCHING ELEMENT
Document Type and Number:
WIPO Patent Application WO/2013/190988
Kind Code:
A1
Abstract:
The present invention provides a non-volatile switching element that can be applied to a programmable-logic wiring changeover switch and in which an electrochemical reaction is used. Of the two electrodes for applying a bias voltage to the variable resistance layer of the non-volatile switching element, the electrode that does not feed metal ions to the variable resistance layer when the switch is in the ON state is made from a ruthenium alloy. The ruthenium alloy comprises ruthenium and a metal in which the standard Gibbs energy of formation ΔG when metal ions are generated from the metal is higher in the negative direction than ΔG of ruthenium. As a result, it becomes possible to maintain the low-resistance state in the ON state for a longer period of time without increasing the amount of electrical current required when a switch is made between the ON state and the OFF state.
