摘要： An improved mold, for use in the formation of a perpendicular magnetic write head, is described, together with a process for its manufacture. Conventional alumina is replaced by tantalum in the yoke portion of the mold. When both the tantalum and the alumina areas are simultaneously subjected to reactive ion etching, sloping sidewalls are obtained in the alumina area (write pole tip portion) whereas the sidewalls are almost vertical in the tantalum (yoke) area, resulting in a uniform neck height.

摘要： A method for independently forming neck height (NH) and pole width dimensions in a main pole layer of a PMR write head is described. A main pole layer with a pole tip region is formed on a bottom yoke. The pole tip region is trimmed by an ion milling process to give a pole width. A bilayer resist is patterned to form an opening with an undercut on the main pole layer. The opening uncovers the pole tip region except for an NH length adjacent to the pole tip. A top yoke comprised of CoFeN with a thickness of about 0.2 microns is deposited in the opening and the bilayer resist is removed by a lift-off process. Thereafter, a write gap layer is formed on the pole tip region and then first, second, and third write shield layers are formed above the write gap layer along the ABS.

摘要： A main pole layer is deposited within an opening in a patterned photoresist layer on a substrate. The photoresist is thinned to expose an upper portion of a pole tip region that is then trimmed to a rectangular shape while a lower portion retains an inverted trapezoidal shape. Thereafter, a second trimming process forms a pole tip with a first width in the upper rectangular portion and a second thickness and second width which is less than the first width in the lower portion. A CMP step subsequently thins the upper portion to a first thickness of 0.04 to 0.08 microns while the second thickness remains at 0.16 to 0.32 microns. The bottom surface of the lower portion along the ABS becomes the trailing edge in a recording operation. The pole tip has a consistent first width (track width) that is not influenced by CMP process variations.
