    摘要: A method for fabricating a magnetic head with a trapezoidal shaped pole piece tip is described. The body of the main pole piece is deposited; then one or more layers for the pole piece tip are deposited. A bed material is deposited over the pole piece tip material. A void is formed in the bed material over the area for the pole piece tip. The void is filled with an ion-milling resistant material such as alumina preferably using atomic layer deposition or atomic layer chemical vapor deposition. The excess ion-milling resistant material and the bed material are removed. The result is an ion-milling mask formed over the area for the pole piece tip. Ion milling is then used to remove the unmasked material in the pole piece tip layer and to form a beveled pole piece tip and preferably a beveled face on the main pole piece.

    摘要: A contact magnetic transfer (CMT) master template is made by first adhering a plastic film to a first surface of a silicon wafer. A resist pattern is then formed on the polyimide film and the polyimide is reactive-ion-etched through the resist to form recesses. The resist is removed and a chemical-mechanical-polishing (CMP) stop layer is deposited over the non-recessed regions of the polyimide, and optionally into the bottoms of the recesses. A layer of magnetic material is then deposited over the polyimide film to fill the recesses. A CMP process is then performed to remove magnetic material above the recesses and above the non-recessed regions and continued until the CMP stop layer is reached. The resulting upper surface of the polyimide film is then a continuous planar film of magnetic islands and regions of CMP stop layer material that function as the nonmagnetic regions of the template.

    摘要: A method for nano-patterning includes imprinting features in a resist with an imprint mold to form one or more topographic surface patterns on the imprinted resist. A a block copolymer (“BCP”) material is deposited on the imprinted resist, wherein a molecular dimension L0 of the BCP material correlates by an integer multiple to a spacing dimension of the one or more topographic surface patterns on the imprinted resist. The deposited BCP is annealed and at least a portion of the annealed BCP is removed, forming a template having discrete domains.

    摘要: A narrow track-width magnetoresistive sensor by defining a trench formed between first and second hard bias layers and depositing the sensor into the trench. The sensor can include a sensor stack sandwiched between first and second electrically conductive lead layers. First and second electrically insulating side walls are formed at either side of the sensor stack. First and second hard bias layers extend from the sides of the sensor stack, being separated from the sensor stack by the first and second electrically insulating side walls. First and second physically hard insulation layers are provided over each of the hard bias layers.
