摘要： The present invention relates to nonaqueous electrolyte secondary batteries and durable anode materials and anodes for use in nonaqueous electrolyte secondary batteries. The present invention also relates to methods for producing these anode materials. In the present invention, a metal-semiconductor alloy layer is formed on an anode material by contacting a portion of the anode material with a displacement solution. The displacement solution contains ions of the metal to be deposited and a dissolution component for dissolving a part of the semiconductor in the anode material. When the anode material is contacted with the displacement solution, the dissolution component dissolves a part of the semiconductor in the anode material thereby providing electrons to reduce the metal ions and deposit the metal on the anode material. After deposition, the anode material and metal are annealed to form a uniform metal-semiconductor alloy layer.

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.
