    摘要: A read sensor for a transducer is fabricated. The transducer has a field region and a sensor region corresponding to the sensor. A sensor stack is deposited. A hybrid mask including hard and field masks is provided. The hard mask includes a sensor portion covering the sensor region and a field portion covering the field region. The field mask covers the field portion of the hard mask. The field mask exposes the sensor portion of the hard mask and part of the sensor stack between the sensor and field regions. The sensor is defined from the sensor stack in a track width direction. Hard bias layer(s) are deposited. Part of the hard bias layer(s) resides on the field mask. Part of the hard bias layer(s) adjoining the sensor region is sealed. The field mask is lifted off. The transducer is planarized.

    摘要: A method of forming a near field transducer (NFT) for energy assisted magnetic recording is disclosed. A structure comprising an NFT metal layer and a first hardmask layer over the NFT metal layer is provided A first patterned hardmask is formed from the first hardmask layer, the first patterned hardmask disposed over a disk section and a pin section of the NFT to be formed. An etch process is performed on the NFT metal layer via the first patterned hardmask, the etch process forming the NFT having the disk section and the pin section.

    摘要: A method of forming an energy assisted magnetic recording (EAMR) writer is disclosed. A structure comprising a bottom cladding layer and a near field transducer (NFT) is provided. A patterned sacrificial layer is formed over the structure. A top cladding layer is deposited over the patterned sacrificial layer and a remaining region of the structure not covered by the patterned sacrificial layer. A patterned resist is formed over the top cladding layer. A first etching operation is performed on the top cladding layer via the patterned resist, whereby a top cladding having a sloped region is formed. The patterned sacrificial layer provides an etch stop for the first etching operation.
