Abstract:
1. A method comprising: forming a first photoresist mask on a substrate, the first photoresist mask comprising inside edges, the inside edges of the first photoresist mask defining a first aperture, the first aperture having a first maximum width; forming a second photoresist mask on the first photoresist mask, the second photoresist mask comprising inside edges, the inside edges of the second photoresist mask defining a second aperture, wherein the second aperture has a second maximum width that is smaller than the first maximum width; depositing near field transducer (NFT) material in at least the second aperture; directionally depositing a cover material on at least the inside edges of the first and second photoresist masks forming a third aperture, the third aperture having a third maximum width, the third maximum width being smaller than the second maximum width; depositing heat sink materials in at least the third aperture; and removing at least a portion of the first photoresist mask, at least a portion of the second photoresist mask, at least a portion of the NFT material, at least a portion of the cover material, and at least a portion of the heat sink material.
