  • Patent number: 10614953
    Abstract: Various embodiments to mitigate the contamination of electroplated cobalt-platinum films on substrates are described. In one embodiment, a device includes a substrate, a titanium nitride diffusion barrier layer formed upon the substrate, a titanium layer formed upon the titanium nitride diffusion barrier layer, a platinum seed layer, and a cobalt-platinum magnetic layer formed upon the platinum seed layer. Based in part on the use of the titanium nitride diffusion barrier layer and/or the platinum seed layer, improvements in the interfaces between the layers can be achieved after annealing, with less delamination, and with substantial improvements in the magnetic properties of the cobalt-platinum magnetic layer. Further, the cobalt-platinum magnetic layer can be formed at a relatively thin thickness of hundreds of nanometers to a few microns while still maintaining good magnetic properties.
