Abstract

A method involves forming a metal layer on a metal seed layer, the metal seed layer formed on a carrier wafer. A surface of the metal layer defines a first metal bonding layer. A second metal bonding layer is provided on a target substrate having recording head subassemblies. Mating surfaces of the first and second metal bonding layers are activated and the carrier wafer is flipped and joined with the target substrate such that the first and second metal bonding layers are bonded and the metal layer is integrated with the recording head as a near-field transducer.
