Abstract:
Methods that include depositing a first layer over the entire surface of a structure, the structure having a magnetic reader and a magnetic writer, wherein the magnetic reader and the magnetic writer are positioned adjacent to each other on a substrate and the magnetic writer includes a near field transducer (NFT); depositing a second layer over the entire surface of the first layer; depositing a photoresist material layer over the entire surface of the second layer, the photoresist material layer having a bottom surface in contact with the second layer and an opposing top surface; exposing the photoresist material layer to radiation through the bottom surface of the photoresist material layer via the NFT to form a first exposed region; and exposing the photoresist material layer to radiation through the top surface of the photoresist material layer to form a second exposed region.
