Abstract:
1. A method of forming an energy assisted magnetic recording (EAMR) writer, the method comprising: providing a structure comprising a bottom cladding layer and a near field transducer (NFT); forming a patterned sacrificial layer over the structure; depositing a top cladding layer over the patterned sacrificial layer and a remaining region of the structure not covered by the patterned sacrificial layer; forming a patterned resist over the top cladding layer; and performing a first etching operation on the top cladding layer via the patterned resist, whereby a top cladding having a sloped region is formed, wherein the patterned sacrificial layer provides an etch stop for the first etching operation; and wherein the NFT is disposed in a groove formed in the bottom cladding layer, wherein a to surface of the NFT is coplanar with a top surface of the bottom cladding layer.
