Abstract

Disclosed is a method of fabricating a magnetic memory device. The method of a fabricating a magnetic memory device includes forming an interlayer dielectric layer on a substrate, forming a sacrificial pattern in the interlayer dielectric layer, forming a magnetic tunnel junction pattern on the sacrificial pattern, after forming the magnetic tunnel junction pattern, selectively removing the sacrificial pattern to form a bottom contact region in the interlayer dielectric layer, and forming a bottom contact in the bottom contact region.
