摘要: Provided are a magnetic memory device and a method of forming the same. The magnetic memory device includes a magnetic tunnel junction pattern located on a substrate and including magnetic patterns and a tunnel barrier pattern located between the magnetic patterns, and a first crystallinity conserving pattern located on the magnetic tunnel junction pattern and having a higher crystallization temperature than the magnetic patterns. The first crystallinity conserving pattern is amorphous.

摘要: A cleaning method for removing foreign bodies during the fabrication of semiconductor devices including treating a substrate with a cleaning solution including an oxidizer to form a chemical oxide layer and then removing the chemical oxide layer, thereby removing foreign bodies from a surface of the semiconductor substrate. Accordingly, the foreign bodies can be substantially removed from the surface of the substrate without corroding a metal.

摘要: A MRAM device may include a fixed layer pattern on a substrate, a first tunnel barrier layer pattern on the fixed layer pattern, a free layer pattern on the first tunnel barrier layer pattern, a second tunnel barrier layer pattern on the free layer pattern, the second tunnel barrier layer pattern including a metal oxide, and a capping layer pattern on the second tunnel barrier layer pattern. The capping layer pattern including a metal may have an oxide layer formation energy lower than the oxide layer formation energy of tantalum.
