US 8,426,935 B2 · Electronic device, memory device, and method of fabricating the same

Abstract

Provided are an electronic device, a memory device, and a method of fabricating the devices for preventing physical distortion of functional elements from generating and improving electric contact properties between the functional elements and electric elements connecting to the functional elements. At least two grooves are formed in a substrate, and a conductive material is filled in the grooves to obtain electric elements having a surface at the same height as that of the substrate. In addition, a functional material layer (functional layer) is formed on an entire upper surface of the substrate and is patterned so as to obtain a functional element having both bottom surfaces contacting the electric elements.

A method of fabricating an electronic device having a pair of electrodes and a functional layer positioned between the electrodes and providing a current path between the electrodes, the method comprising:

forming a pair of grooves in a surface of a substrate;
forming a pair first material layers for the pair of electrodes by filling a first electronic material in the pair of the grooves;
and
forming a second material layer for the functional layer between the pair of the electrodes by using a second electronic material that is oxidized easier than the first electronic material, so as to contact the first material layers on the substrate,
wherein the first material layer is a conductive material, and the second material is a ferromagnetic material.
