An amorphous soft magnetic thin film material for forming shielding and keeper applications in MRAM devices. The amorphous soft magnetic material may be deposited using Physical Vapor Deposition (PVD) in the presence of a magnetic field, in order to form shielding layers and keepers in a multi-layer metallization process. The soft magnetic material may be an amorphous metallic alloy, such as CoZrX, where X may be Ta, Nb, Pd and/or Rh.

Amorphous soft magnetic shielding and keeper for MRAM devices

A method and apparatus for fabricating a conformal thin film on a substrate are disclosed. The method includes introducing a gas from a gas inlet into an expansion volume associated with an atomic layer deposition (ALD) system. The gas is flowed through a diffuser plate adjacent to the expansion volume and a reaction chamber. The diffuser plate includes a protrusion located opposite the gas inlet and the protrusion reduces turbulence in the expansion volume.

Method and apparatus for fabricating a conformal thin film on a substrate

This invention is directed to methods for depositing multilayered thin films onto substrates, for example in making thin film magnetic heads. In accordance with the invention a first film, such as Cr, is deposited onto the substrate at a first pressure and a second layer, such as CoCrPt is deposited at a second pressure.

Method of depositing multilayer thin films

This invention is directed to methods for depositing multilayered thin films onto substrates, for example in making thin film magnetic heads. In accordance with the invention a first film, such as Cr, is deposited onto the substrate at a first angle and a second layer, such as CoCrPt is deposited at a second angle.
