摘要:
A method of making a transducer head disclosed herein includes depositing a spacer layer on an NFT layer of the transducer head, forming an etch stop layer on a spacer layer of a transducer, depositing a cladding layer on the etch stop layer, and milling the cladding layer at a sloped angle such that the milling stops at the etch stop layer.
摘要:
When opaque films are deposited on semi-conductor wafers, underlying alignment marks may be concealed. The re-exposure of such alignment marks is one source of resulting surface topography. In accordance with one implementation, alignment marks embedded in a wafer may be exposed by removing material from one or more layers and by replacing such material with a transparent material. In accordance with another implementation, the amount of material removed in an alignment mark recovery process may be mitigated by selectively ashing or etching above a stop layer.

摘要:
The disclosed methods enable the production of plasmonic near-field transducers that are useful in heat-assisted magnetic recording. The plasmonic near-field transducers have an enlarged region and a peg region. The peg region includes a peg region in proximity to an air-bearing surface above a recording medium and also includes a flared region between and in contact with the enlarged region and the peg region. The flared region can act as a heat sink and can lower the thermal resistance of the peg portion of the near-field transducer, thus reducing its temperature.
