Abstract: A method of manufacturing a magnetic memory device may include forming a bottom electrode layer on a substrate; forming a block structure on the bottom electrode layer; performing a first deposition process on the bottom electrode layer to form a pinned magnetic layer, a tunnel barrier layer, and a free magnetic layer on the bottom electrode layer; performing a second deposition process on the free magnetic layer to form a capping layer on the free magnetic layer; and performing an etching process after forming a hard mask on the capping layer to form magnetic tunnel junction patterns. The first deposition process may include irradiating a first beam toward the substrate. The second deposition process may include irradiating a second beam toward the substrate. The second beam may have a greater angle than the first beam with respect to a normal line perpendicular to an upper surface of the substrate.
