摘要:
Using a beam of xenon ions together with a suitable mask, a GMR stack is ion milled until a part of it, no more than about 0.1 microns thick, has been removed so that a pedestal, having sidewalls comprising a vertical section that includes all of the free layer, has been formed. This is followed by formation of the dielectric and conductive lead layers in the usual way. Using xenon as the sputtering gas enables the point at which milling is terminated to be more precisely controlled.

Using a beam of xenon ions together with a suitable mask, a stack is ion milled until a part of it, no more than about 0.1 microns thick, has been removed so that a pedestal having sidewalls, including a vertical section and a shortened taper portion, has been formed. This is followed by formation of conductive lead layers as needed. Using xenon as the sputtering gas enables the point at which milling is terminated to be more precisely controlled.

摘要:
A GMR read pillar formed by ion milling has both vertical and sloping sidewall sections with the free layer normally being located within the latter. Using xenon as the sputtering gas enables the vertical section of the pedestal to be made longer, relative to the sloping portion, without requiring an increase in the sputtering rate, so the free layer can have vertical sidewalls. This allows the point at which milling is terminated to be controlled more precisely and, by more precisely defining the width of the free layer, also improves design tolerances.
摘要:
We describe a family of magnetic read heads that each includes a GMR or MTJ stack. A part, no more than about 0.1 microns thick, has been removed from this stack a to form a pedestal having sidewalls comprising a vertical section that includes all of the free layer.

摘要:
A method for forming a plated magnetic thin film of high saturation magnetization and low coercivity having the general form Co100−a−bFeaMb, where M can be Mo, Cr, W, Ni or Rh, which is suitable for use in magnetic recording heads that write on narrow trackwidth, high coercivity media. The plating method includes four current application processes: direct current, pulsed current, pulse reversed current and conditioned pulse reversed current.
