Abstract
A first layer that includes a metal seed layer, a refractive seed or a refractive dopant is formed on a dielectric substrate. A peg of a near-field transducer is formed on the first layer such that a first surface of the peg is formed on and is in contact with the metal seed. An adhesive layer is formed over the peg using atomic layer deposition. The adhesive layer includes alumina and is 4 nm or less in thickness. A silicon dioxide overcoat is deposited over the adhesive layer. The alumina bonds the silicon dioxide to the peg.
