  • Publication number: 20240145381
    Abstract: In some embodiments, the present disclosure relates an integrated chip including a substrate. A conductive interconnect feature is arranged over the substrate. The conductive interconnect feature has a base feature portion with a base feature width and an upper feature portion with an upper feature width. The upper feature width is narrower than the base feature width such that the conductive interconnect feature has tapered outer feature sidewalls. An interconnect via is arranged over the conductive interconnect feature. The interconnect via has a base via portion with a base via width and an upper via portion with an upper via width. The upper via width is wider than the base via width such that the interconnect via has tapered outer via sidewalls.

  • Publication number: 20240099150
    Abstract: A method includes forming Magnetic Tunnel Junction (MTJ) stack layers, which includes depositing a bottom electrode layer; depositing a bottom magnetic electrode layer over the bottom electrode layer; depositing a tunnel barrier layer over the bottom magnetic electrode layer; depositing a top magnetic electrode layer over the tunnel barrier layer; and depositing a top electrode layer over the top magnetic electrode layer. The method further includes patterning the MTJ stack layers to form a MTJ; and performing a passivation process on a sidewall of the MTJ to form a protection layer. The passivation process includes reacting sidewall surface portions of the MTJ with a process gas comprising elements selected from the group consisting of oxygen, nitrogen, carbon, and combinations thereof.
