Abstract
Methods that include forming at least a portion of a near field transducer (NFT) structure; depositing a material onto at least one surface of the portion of the NFT to form a metal containing layer; and subjecting the metal containing layer to conditions that cause diffusion of at least a portion of the material into the at least one surface of the portion of the NFT; and devices formed thereby.
Claims20
A method comprising:
- forming at least a portion of a near field transducer (NFT) structure;
- depositing a material onto at least one surface of the portion of the NFT to form a metal containing layer;
- subjecting the metal containing layer to conditions that cause diffusion of at least a portion of the material into the at least one surface of the portion of the NFT.
A method comprising:
- forming at least a portion of a near field transducer (NFT) structure;
- depositing a material onto at least an air bearing surface of the NFT to form a metal containing layer;
- subjecting the metal containing layer to conditions that cause diffusion of at least a portion of the material into the at least one surface of the portion of the NFT;
- removing at least a portion of the metal containing layer;
- and
- applying an overcoat layer.

A method comprising:
- forming at least a portion of a near field transducer (NFT) structure;
- depositing a material onto at least an air bearing surface of the NFT to form a metal containing layer;
- removing a portion of the metal containing layer not on the air bearing surface of the NFT;
- subjecting the metal containing layer to conditions that cause diffusion of at least a portion of the material into the at least one surface of the portion of the NFT;
- removing at least a portion of the metal containing layer;
- and
- applying an overcoat layer.
