Summary:A process of forming an electronic device can include forming a stack including a tunnel barrier layer. The tunnel barrier layer can have a ratio of the metal atoms to oxygen atoms of greater than a stoichiometric ratio, wherein the ratio has a particular value. The process can also include forming a gettering layer having a composition capable of gettering oxygen, and depositing an insulating layer over the gettering layer. The process can further include exposing the insulating layer to a temperature of at least approximately 60° C. In one embodiment, after such exposure, a portion of the gettering layer is converted to an insulating material. In another embodiment, an electronic device can include a magnetic tunnel junction and an adjacent insulating layer lying within an opening in another insulating layer.
