发明名称 Method of forming a magnetic tunnel junction structure
摘要 In a particular illustrative embodiment, a method of forming a magnetic tunnel junction (MTJ) device is disclosed that includes forming a trench in a substrate. The method further includes depositing a magnetic tunnel junction (MTJ) structure within the trench. The MTJ structure includes a bottom electrode, a fixed layer, a tunnel barrier layer, a free layer, and a top electrode. The method also includes planarizing the MTJ structure. In a particular example, the MTJ structure is planarized using a Chemical Mechanical Planarization (CMP) process.
