    摘要: A method of patterning magnetic devices and sensors by double etching, which includes forming a layer of dielectric on a substrate; depositing a thin adhesion layer and a thin seed layer; applying a thin resist frame to pattern a structure; cleaning the metal surface to prepare for plating; electroplating to fill up the structure and the uncovered field area, which uses a paddle cell with a permanent magnet providing magnetic field to induce magnetic orientation; stripping the resist frame; etching the seed layer/adhesion layer exposed below the resist frame down to the dielectric surface; etching the rest of magnetic materials and the seed layer using electrolytic etching in the field; etching the adhesion layer in the field, and repeating the steps for building structures with multiple levels.

    摘要: A fixture for supporting a workpiece in a processing cell includes a frame and cooperating workpiece holder. The frame includes a head having a hole therein which receives an integral plateau of the holder. The holder plateau includes an annular seal adjacent a perimeter thereof with a vacuum port disposed therein. The workpiece rests on the seal so that vacuum drawn in the vacuum port fixedly holds the workpiece against the plateau. Assembly of the holder plateau and workpiece thereon through the frame-head hole positions the workpiece coplanar with a front side of the frame. In exemplary embodiments, independent electrical current paths are provided to the workpiece and a surrounding auxiliary electrode.

    摘要: An integrated inductive write, magnetoresistive (MR) read thin film magnetic head comprising an open magnetic yoke having outside legs each having a winding thereon and a central leg having an opening across which the MR element is coupled. The outer legs are overlapped at one end to form confronting pole pieces having a transducing gap between the pole pieces, and the central leg is positioned between the pole pieces at one end and joined with the outer legs at the other end to form a symmetrical magnetic yoke structure. The windings are wound in a direction so that the flux produced by equally energizing the windings is equal and opposite in each of the outside legs, is additive at the transducing gap between the pole pieces, and produces no net flux through the central leg.
