    摘要: Embodiments of the present invention pertain to forming a head with reduced pole tip recession. According to one embodiment, a pole tip element is formed from a platinum containing material. During diamond like carbon (DLC) processing, hydrogen and hydrogen containing compounds are removed from a vacuum plasma processing environment that contains the head so that an amount of material that is removed from the pole tip element and other non-platinum containing elements associated with the head are approximately the same.

    摘要: A method of physical vapor deposition (PVD) is disclosed in which xenon is used as the operating gas in the vacuum chamber in the deposition of an adhesion layer, preferably silicon, which allows the adhesion layer to be ultra-thin with improved durability over prior art films. The use of argon as is typical in the prior art results in argon atoms being incorporated into the ultra-thin silicon film with deleterious results. In films that are only several angstroms thick, the contamination of the film with argon or other elements can yield a film with reduced adhesion performance and in some cases noble atoms such as argon can escape the film leaving voids or pinholes. The use of the larger and heavier xenon atoms in the vacuum chamber produces a substantially purer film with reduced risk of voids and pinholes. In a preferred embodiment the use of xenon as the operating gas for deposition of the silicon adhesion layer is combined with the use of a filtered cathodic arc (FCA) process to deposit the protective overcoat, preferably carbon based, on a magnetic recording head.

    摘要: A method for manufacturing a magnetic write head having a write pole with a tapered leading edge formed on a substrate having a tapered surface and a wrap-around, trailing magnetic shield. The method uses a multi-layer anti-reflective coating prior to formation of the shield so that reflection from the tapered surface of the substrate does not affect the lithography of the mask used to form the trailing shield. The multi-layer antireflective coating is constructed of materials that can be left in the finished head, thereby eliminating problems associated with removal of the anti-reflective coating.

    摘要: A method for manufacturing a magnetoresistive sensor that results in the sensor having a very flat top magnetic shield. The process involves depositing a plurality of sensor layers and then depositing a thin high density carbon CMP stop layer over the sensor layers and forming a mask over the CMP stop layer. An ion milling is performed to define the sensor. Then a thin insulating layer and magnetic hard bias layer are deposited. A chemical mechanical polishing is performed to remove the mask and a reactive ion etching is performed to remove the remaining carbon CMP stop layer. Because the CMP stop layer is very dense and hard, it can be made very thin. This means that when it is removed by reactive ion etching, there is very little notching over the sensor, thereby allowing the upper shield (deposited there-over) to be very thin.

    摘要: An improved method of fabricating thin-film magnetic recording heads is disclosed. For the method, one or more layers for a feature (such as a read element, a write element, etc) are deposited and patterned. A layer of adhesion material is then deposited on the layers of the feature. The adhesion material provides better adhesion to a Diamond-Like Carbon (DLC) layer and to the underlying feature surface, such as monolithic Silicon (Si) or Titanium (Ti). A layer of DLC material is then deposited on the layer of adhesion material. The steps of depositing the layer of adhesion material and the layer of DLC material are repeated more than one time. Thus, more than one set of alternating layers of adhesion material and DLC material are deposited on the layers of the feature to form a multi-layer protective coating on the feature.

    摘要: A magnetic recording head with reduced thermally induced protrusion. In one embodiment, a thermal expansion constraining layer comprising silicon dioxide for instance overlays a magnetic recording head. The thermal expansion constraining layer has a very low coefficient of thermal expansion. A sealant layer comprising aluminum oxide overlays the thermal expansion constraining layer. The thermal expansion constraining layer prevents deleterious deformation of underlying head structures that can degrade performance of a storage system. The sealant layer protects the thermal expansion constraining layer from propagation of surface defects therein by protection from shock, including shock during fabrication, as well as moisture, increasing manufacturing yield and reliability.
