摘要： A perpendicular write head having a wrap around shield and a conformal side gap. In fabricating the write head, the leading edge shield may be chemical mechanical polished down to a level that is substantially even with a chemical mechanical polishing stop layer. Because the leading edge shield and the chemical mechanical polishing stop layer are used as RIE stop for trench RIE, a fully conformal side shield may be formed with a LTE/LES.

摘要： A magnetic write head having a tapered trailing edge and having a magnetic layer formed over a trailing edge of the write pole at a location recessed from the ABS, the magnetic layer being separated from the trailing edge of the write pole by a thin non-magnetic layer. The thin non-magnetic layer is preferably sufficiently thin that the magnetic layer can function as a portion of the write pole in a region removed from the ABS. A trailing magnetic shield is formed over the write pole and is separated from the write pole by a non-magnetic trailing gap layer. A non-magnetic spacer layer can be formed over the magnetic layer to provide additional separation between the magnetic layer and the trailing magnetic shield.

摘要： Methods for fabrication of leading edge shields and tapered magnetic poles with a tapered leading edge are provided. The leading edge shield may be formed by utilizing a CMP stop layer. The CMP stop layer may aid in preventing over polishing of the magnetic material. For the tapered magnetic poles with a tapered leading edge, a magnetic material is deposited on a planarized surface, a patterned resist material is formed, and exposed magnetic material is etched to form at least one tapered surface of the magnetic material.

摘要： The present disclosure describes a method for manufacturing a full wraparound shield damascene write head through the implementation of a three layered (tri-layered) hard mask. According to an embodiment of the invention, the various layers of hard mask are used for different purposes during the formation of a write head. The wraparound shield head of the present invention exhibits improved physical characteristics that further result in improved performance characteristics. Use of the hard mask layers according to the present invention allows for use of manufacturing processes that can be more closely controlled than those processes used in other processes. For example, smaller dimension lithographic techniques can be used. Also, reliance on certain CMP processes is not necessary where the use of CMP processes is not as well-controlled as deposition or lithographic techniques as is possible using the present invention.
