  • Near field transducer with template layer for improved reliability
    Patent number: 12288568
    Abstract: A method of fabricating a near field transducer (NFT) in a thermally assisted magnetic recording (TAMR) head is disclosed. In some embodiments, the method includes: depositing a dielectric layer and a template layer on a waveguide core; patterning the template layer to form a template; depositing an Au NFT layer; planarizing the Au NFT layer to generate a planar layer; depositing an upper NFT layer; applying a peg patterning mask; etching the upper NFT layer and the planar layer that includes the Au NFT layer; removing the template; and depositing a dielectric material and planarizing an upper surface that includes the upper NFT layer.
