    摘要: An indium cap layer is formed by blanket depositing indium onto a surface of metallic interconnects separated by interlayer dielectric, and then selectively chemically etching the indium located on the interlayer dielectric leaving an indium cap layer. Etchants containing a strong acid are provided for selectively removing the indium.

    摘要: A semiconductor device includes a substrate including an M2 patterned area. A VA pillar structure is formed over the M2 patterned area. The VA pillar structure includes a substractively patterned metal layer. The VA pillar structure is a sub-lithographic contact. An MTJ stack is formed over the oxide layer and the metal layer of the VA pillar. A size of the MTJ stack and a shape anisotropy of the MTJ stack are independent of a size and a shape anisotropy of the sub-lithographic contact.
