  • Publication number: 20250182963
    Abstract: A method of fabricating high magnetic anisotropy materials using a metallic high entropy alloy is described in this disclosure. Targets of metals or targets of alloys comprising at least one elemental ferromagnetic material are used in a sputtering tool to deposit on a substrate thin films of high entropy alloys. The sputtering targets may be elemental targets or they may comprise multiple metals. In addition, targets of materials such as boron, platinum, or aluminum may be included in the sputtering process to enhance magnetic properties of the resultant thin films. The sputtering may take place by co-sputtering multiple targets simultaneously or by alternatively sputtering layers from the targets. After sputtering the materials are heated through a rapid thermal annealing process to a high temperature, which facilitates the formation of the desired crystalline phases which exhibit high magnetocrystalline anisotropy.

  • Publication number: 20250147222
    Abstract: The disclosure describes an improved drop-on-demand, controlled volume technique for dispensing resist onto a substrate, which is then imprinted to create a patterned optical device suitable for use in optical applications such as augmented reality and/or mixed reality systems. The technique enables the dispensation of drops of resist at precise locations on the substrate, with precisely controlled drop volume corresponding to an imprint template having different zones associated with different total resist volumes. Controlled drop size and placement also provides for substantially less variation in residual layer thickness across the surface of the substrate after imprinting, compared to previously available techniques. The technique employs resist having a refractive index closer to that of the substrate index, reducing optical artifacts in the device.
