  • Thin film coating and method of fabrication thereof
    Patent number: 11274360
    Abstract: A method and a system for film deposition, the system comprising a substrate and a negatively biased target, the target being mounted on a magnetron sputtering cathode and located at a distance from the substrate, wherein a laser beam from a pulsed laser is focused on the target, thereby triggering a magnetron plasma or ejecting vaporized and ionized material from the target in an existing magnetron plasma, the magnetron plasma sputtering material from the target depositing on the substrate.
    Type: Grant
    Filed: December 13, 2017
    Date of Patent: March 15, 2022
