    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： 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： A method for reducing plated pole height loss in the formation of a write pole for a magnetic write head is disclosed. The method includes forming a conductive layer on a thin film substrate, forming a photoresist layer on the conductive layer and forming a trench in the photoresist layer. A thick seed layer is then placed on the trench and on the photoresist layer surface using a collimator. Moreover, the process includes plating while applying a voltage to the thin film substrate where the electrically isolated seed layer is removed and the trench is filled with plating material, removing the photoresist layer, and removing the exposed portions of the conductive layer on the thin film substrate.

    摘要： An apparatus for patterning a self-aligned coil using a damascene process is disclosed. Coil pockets are formed in a first insulation layer disposed over a first pole layer. A barrier/seed layer is deposited along walls of the coil pockets in the insulation layer. Copper is formed in the coil pockets and over the insulation layer. The copper is planarized down to the insulation layer. The self-aligned coil process packs more copper into the same coil pocket and relaxes the coil alignment tolerance. Protrusions are prevented because of the more efficient and uniform spacing of the coil to reduce heat buildup in the head during a write.

    摘要： After defining the P2 pole of a magnetic read head, alumina is deposited over it and planarized by CMP, with the portion of the alumina overlaying the ABS region of the P2 pole subsequently being masked by a photoresist layer and with the portions of the alumina overlaying the flare area, back gap region, and center tap regions of the P2 pole not being masked. A reactive ion mill is performed to expose the flare area, back gap region, and center tap regions of the P2 pole by removing the alumina over these portions, so that subsequent steps such as forming a layer of coiled conductors, forming a return pole, and forming stud connections along with removing the respective seed layers can be executed with the ABS region protected by the alumina and with the flare area, back gap region, and center tap region exposed.
