Abstract

A method of fabricating a variable resistance memory device includes: forming a bottom electrode on a substrate; forming a dielectric layer on the substrate, wherein the dielectric layer has a first trench that exposes the bottom electrode; forming a variable resistance layer in the first trench; and irradiating the variable resistance layer with a laser, wherein the variable resistance layer is irradiated by the laser for a time of about 1.8 μs to about 54 μs.
