Abstract
A method of forming a near field transducer (NFT) layer, the method including depositing a film of a primary element, the film having a film thickness and a film expanse; and implanting at least one secondary element into the primary element, wherein the NFT layer includes the film of the primary element doped with the at least one secondary element.
Claims9
A method of forming a peg of a near field transducer (NFT), the method comprising:
- depositing a primary element to form a primary element film or layer;
- defining a peg of the NFT from the primary element film or layer;
- forming the peg of the NFT;
- encapsulating the peg with an encapsulation layer;
- defining an implant;
- and
- implanting at least one secondary element in the implant area of the primary element film to form the peg of the NFT.
4 more elements
A method of forming a plurality of magnetic heads, each of the magnetic heads comprising an alloyed peg of a NFT, the method comprising:
- depositing a primary element on a substrate to form a primary element film or layer;
- forming a plurality of pegs of the NFTs;
- slicing the substrate into rows, each row containing a plurality of pegs;
- depositing head overcoat material on each row;
- and
- implanting at least one secondary element in the primary element film of the peg to form an alloyed peg of a NFT.
