摘要： A magnetic write head and method of manufacture thereof that has a first pole structure having a notched structure configured with a steep shoulder portion and a narrow vertical notch portion extending from the top of the steep shoulder portion. The write head also includes a second pole structure (P2) that has a very narrow width (track width) and that is self aligned with the narrow vertical notch structure of the first pole structure. The write head provides excellent magnetic properties including a very narrow track width and minimal side writing, while avoiding magnetic saturation of the poles.

摘要： A method and apparatus for integrating a stair notch and a gap bump at a pole tip in a write head is disclosed. A protective plated layer is formed over the bump to prevent the bump form being damaged during formation of the notch at the pole tip. The flux from the second pole outside of the track will be effectively channeled to the first pole piece under the alumina bump.

摘要： One preferred method for use in making a magnetic write head with use of the resist channel shrinking solution includes the steps of forming a first pole piece layer of a first pole piece; forming a gap layer over the first pole piece layer; forming a patterned resist over the first pole piece layer and the gap layer; electroplating a first pedestal portion of a second pole piece over the gap layer within a channel of the patterned resist; forming an oxide layer over the first pedestal portion; applying the resist channel shrinking solution comprising the resist channel shrinking film and the corrosion inhibitors over the patterned resist; baking the resist channel shrinking solution over the patterned resist to thereby reduce a width of the channel; removing the resist channel shrinking solution; electroplating a second pedestal portion of the second pole piece within the reduced-width channel of the patterned resist; removing the patterned resist; and milling the structure. Advantageously, the oxide layer and the corrosion inhibitors of the resist channel shrinking solution reduce corrosion in the pole piece during the act of baking the resist channel shrinking solution.

摘要： The present invention discloses a method for the production of sub-micron structures on magnetic materials using electron beam lithography. A subtractive process is disclosed wherein a portion of a magnetic material layer is removed from the substrate using conventional lithography, and the remaining portion of the magnetic material layer is patterned by e-beam lithography. A additive process is also disclosed wherein a thin magnetic seed layer is deposited on the substrate, a portion of which is removed by conventional lithography and replaced with a non-magnetic conducting layer. The remaining portion of magnetic seed layer is patterned by e-beam lithography and the final magnetic structure produced by electroplating.
