  • Patent number: 10763429
    Abstract: Embodiments of the present invention are directed to a method for fabricating a magnetoresistive random access memory (MRAM) device. A non-limiting example of the method includes depositing a dielectric layer on a contact arranged on a substrate including a magnetic tunnel junction (MTJ) pillar. The method includes reducing a width of the MTJ pillar. The method further includes depositing an encapsulation layer on the dielectric layer and the MTJ pillar.
    Type: Grant

  • Patent number: 5480748
    Abstract: A conductive layer in a semiconductor device is protected against chemical attack by a photoresist developer by forming a protective film overlying the conductive layer. The protective film is formed using a chemical reaction that occurs through defects in a passivation layer that was previously formed overlying the conductive layer. The chemical reaction substantially occurs at the surface of the conductive layer and chemically converts portions thereof in forming the protective film. Preferably, the conductive layer is aluminum or an alloy thereof containing copper and/or silicon, and the protective film is aluminum oxide formed on the aluminum layer to protect it from corrosion by tetramethyl ammonium hydroxide (TMAH). The passivation layer is TiN, and the chemical reaction used is oxidation of the aluminum layer through defects in the overlying TiN layer by placing in an ozone asher.
