摘要: Provided are semiconductor devices and methods of fabricating the same. The semiconductor device may include lower wires, upper wires crossing the lower wires, select elements provided at intersections between the lower and upper wires, and memory elements provided between the select elements and the upper wires. Each of the memory elements may include a lower electrode having a top width greater than a bottom width, and a data storage layer including a plurality of magnetic layers stacked on a top surface of the lower electrode and having a rounded edge.

摘要: A magnetic memory device and a method of fabricating the same are provided. The method includes forming a first magnetic layer on a substrate, forming a tunnel barrier layer on the first magnetic layer, and forming a second magnetic layer on the tunnel barrier layer. The forming of the tunnel barrier layer includes forming a first metal oxide layer on the first magnetic layer, forming a first metal layer on the first metal oxide layer, forming a second metal oxide layer on the first metal layer, and performing a first thermal treatment process to oxidize at least a portion of the first metal layer.
