    摘要： Rhodium solutions, methods for plating structures using such rhodium solutions, and rhodium plated structures are described. The rhodium solutions can contain an increased concentration of rhodium in the form of a monomer sulfate salt. The rhodium solutions can be formed under conditions of controlled pH and controlled temperatures that increase the uniformity of the chemical composition from one rhodium solution to another. As a result, the shelf life of the rhodium solutions and plating baths using these rhodium solutions can be increased. Rhodium platings formed from these solutions can contain a low degree of dendrites, or even no dendrites. The rhodium platings can also exhibit less internal stress and can be less susceptible to cracking.

    摘要： Improved methods and systems for electroplating wafers are described herein. The method includes the acts of introducing a wafer which is coupled to an electrode into an electroplating cell having a counter electrode; maintaining a flow of a plating solution through the cell for electroplating the wafer; removing the wafer from the cell; stopping the flow of the plating solution through the cell; maintaining a volume of plating solution within the cell sufficient to keep the counter electrode submerged during stoppage of flow; removing the plating solution within the cell; and repeating the above steps for a subsequent wafer. By stopping the flow of plating solution after completion of plating one or more wafers, a consumption rate of additives enhancing electroplating properties is reduced, a production rate of breakdown products produced during electroplating is reduced, plating solution useable life is increased, and a need for plating solution analysis is reduced.

    摘要： A first magnetic shield layer of the read head sensor is deposited upon a slider substrate surface. A patterned photoresist is then photolithographically fabricated upon the first magnetic shield layer with openings that are formed alongside the location at which the read sensor will be fabricated. An ion milling step is performed to create pockets within the surface of the magnetic shield layer at the location of the openings in the photoresist layer. The photoresist layer is then removed, and a fill layer is deposited across the surface of the magnetic shield layer in a depth greater than the depth of the pocket. Thereafter, a polishing step is conducted to remove portions of the fill layer down to the surface of the magnetic shield layer. A G1 insulation layer is deposited and a magnetic head sensor element is then fabricated upon the insulation layer.

    摘要： The present invention includes three-dimensional secondary battery cells comprising an electrolyte, a cathode, an anode, and an auxiliary electrode. The cathode, the anode, and the auxiliary electrode have a surface in contact with the electrolyte. The anode and the cathode are electrolytically coupled. The auxiliary electrode is electrolytically coupled and electrically coupled to at least one of the anode or the cathode. Electrically coupled means directly or indirectly connected in series by wires, traces or other connecting elements. The average distance between the surface of the auxiliary electrode and the surface of the coupled cathode or the coupled anode is between about 1 micron and about 10,000 microns. The average distance means the average of the shortest path for ion transfer from every point on the coupled cathode or anode to the auxiliary electrode.

    摘要： A method for reducing plated pole height loss in the formation of a write pole for a magnetic write head is disclosed. The method includes forming a conductive layer on a thin film substrate, forming a photoresist layer on the conductive layer and forming a trench in the photoresist layer. A thick seed layer is then placed on the trench and on the photoresist layer surface using a collimator. Moreover, the process includes plating while applying a voltage to the thin film substrate where the electrically isolated seed layer is removed and the trench is filled with plating material, removing the photoresist layer, and removing the exposed portions of the conductive layer on the thin film substrate.
