An upper portion of the preliminary first free layer pattern is removed to form a first free layer pattern. A second free layer and a tunnel barrier layer are sequentially formed on the first free layer pattern. The second free layer is partially oxidized to form a second free layer pattern. A fixed layer structure is formed on the tunnel barrier layer."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Magnetoresistive random access memory device and method of manufacturing the same","description":"In a method of manufacturing an MRAM device, a lower electrode and a preliminary first free layer pattern sequentially stacked are formed on a substrate.
