  • Patent number: 8404432
    Abstract: A lithography process for manufacturing bit-island storage mediums that results in improved resolution and uniformity between bit-islands. The lithography process includes applying a resist coating polymer to a surface of a substrate. Selected areas of the resist coating polymer are then exposed to an energy source, wherein each selected area is exposed to the energy source multiple times to provide a time-averaged exposure of the selected areas that reduces errors caused by noise associated with the energy source. After exposure of the resist coating to the energy source, a selective developer solution is applied to the resist coating to develop the fully exposed regions of the resist coating while leaving undeveloped the partially exposed regions of the resist coating. A polymer reflow material is applied to the developed resist pattern and heated to a selected temperature.

  • Publication number: 20130010387
    Abstract: A method for forming a magnetic write pole with a trapezoidal cross-section is described. The method consists of first forming a magnetic seedlayer on a base followed by depositing a removable material layer on the seedlayer, and then a resist layer on the removable material layer. A trench is then formed in the resist, and the resist is heated to cause the cross-sectional profile of the trench to assume a trapezoidal shape. The resist is then capped with another resist layer and further heated to cause the width of the trapezoidal trench to become narrower. The cap layer and removable material layer at the bottom of the trench are then removed and the trench filled with magnetic material by electroplating. The resist and seedlayer external to the trench are finally removed to form a write pole with a trapezoidal cross-section.
