Patent number: 9997566Abstract: Manufacturing an MRAM device may include forming an upper electrode on a magnetic tunnel junction stack, where the stack may include a lower electrode layer, a magnetic tunnel junction layer and a middle electrode layer that are sequentially formed on an insulating interlayer and a lower electrode contact on a substrate. The upper electrode may be formed on the middle electrode layer. An upper electrode protective structure may be formed to cover at least a sidewall and an upper surface of the upper electrode. The middle electrode layer, the magnetic tunnel junction layer and the lower electrode may be patterned by an etching process to form a middle electrode, a magnetic tunnel junction pattern and a lower electrode, respectively. The upper electrode protective structure may isolate the upper electrode from exposure during the patterning, and the upper electrode protective structure may remain on the upper electrode subsequently to the patterning.Type: GrantFiled: May 23, 2017Date of Patent: June 12, 2018Assignee: Samsung Electronics Co., Ltd.Inventors: Sang-Kuk Kim, Jong-Kyu Kim, Jong-Chul Park, Jong-Soon Park, Hye-Ji Yoon, Woo-Hyun Lee
