  • Patent number: 6884335
    Abstract: A negative bias is applied to an integrated circuit wafer immersed in an electrolytic plating solution to generate a DC current. After about ten percent to sixty percent of the final layer thickness has formed in a first plating time, biasing is interrupted during short pauses during a second plating time to generate substantially zero DC current. The pauses are from about 2 milliseconds to 5 seconds long, and typically about 10 milliseconds to 500 milliseconds. Generally, about 2 pauses to 100 pauses are used, and typically about 3 pauses to 15 pauses. Generally, the DC current density during the second plating time is greater than the DC current density during the initial plating time. Typically, the integrated circuit wafer is rotated during electroplating. Preferably, the wafer is rotated at a slower rotation rate during the second plating time than during the first plating time.

    Abstract: Disclosed is a method of electroplating a Ni—Fe—P alloy using a sulfamate solution and, in particular, a method of electroplating a Ni—Fe—P alloy using a plating solution containing nickel sulfamate, iron sulfamate, phosphorous acid, and a buffer agent. The method is advantageous in that a residual stress of a deposited layer is very low and has stable mechanical properties, and excellent thermal and corrosion resistance because the deposited layer is obtained by electroplating the Ni—Fe—P alloy using the sulfamate solution useful in a high rate plating process. Furthermore, the method can be applied to various parent metals such as stainless steel, Inconel and iron alloys, and to various fields because the chemical compositions of the deposited layer are readily controlled by varying the concentration of the plating solution.

  • Patent number: 6773828
    Abstract: An electroplating process reduces the whisker formation rate that results from an interruption of the electroplating process for an alloy. The process forms a tin strike or a thin layer of a pure(>99.9%) metal on the alloy during an activation operation, so that an interruption in the electroplating process during which the lead frame or other work piece remains in an activation solution etches the pure metal layer rather than the alloy and thus does not unacceptably roughen the surface of the work piece. An exemplary embodiment forms a tin strike on a predominantly copper lead frame during an activation operation and forms an Sn—Pb solder layer on the tin strike during a plating operation. The solder layer is generally more than five times as thick as the tin strike layer.

Electroplating compositions of the invention are characterized in significant part by a grain refiner/stabilizer additive comprising one or more non-aromatic compounds having &pgr; electrons that can be delocalized, e.g., an &agr;, &pgr; unsaturated system or other conjugated system that contains a proximate electron-withdrawing group. Compositions of the invention provide enhanced grain refinement and increased stability in metal plating solutions, particularly in tin and tin alloy plating formulations.

  • Publication number: 20040050706
    Abstract: The present invention provides a copper electroplating method using an insoluble anode, including: using an insoluble anode and a copper electroplating solution which contains a compound having a —X—S—Y— structure (where X and Y are each independently selected from the group consisting of a hydrogen atom, a carbon atom, a sulfur atom, a nitrogen atom, and an oxygen atom, and X and Y can be the same only where they are carbon atoms); and using direct current to plate a substrate. By this method, even a certain time period after the initial make-up of the electrolytic bath, stable deposition of the plated metal and formation of a filled via can be achieved, and an MVH can be filled up with the metal with no void left.

  • Patent number: 6699579
    Abstract: We make particulates, especially magnetic Fe—Co alloys having high magnetic permeability, of controlled dimensions, especially those having a narrow thickness size distribution centered around a median or target thickness in the range of about 0.1-1.0 &mgr;m, using electrodeposition typically on a smooth (polished) titanium cathode. Our preferred continuous process uses a rotating drum cathode inside a fixed anode to grow flakes and to produce them automatically by inherent instability in the deposited film. The drum preferably rotates about a substantially vertical axis. The particulates shed (slough off) into the electrolyte (because of mismatch between the cathode surface and the plated metal or alloy at the molecular level) where they are separated in a magnetic separator or other suitable device. If the flakes are soft iron or iron-cobalt alloys, the drum generally is titanium or titanium alloy.

  • Patent number: 6673467
    Abstract: A metallic component exposed to high temperature steam is provided with a coating comprising a thin primer layer deposited on the surface of the metallic component and a thicker overlay layer on top of the primer layer. The primer layer consists of highly ductile, oxidation resistant material such that it remains free of any defects over a long period of exposure. The overlay layer consists of an oxidation resistant, less ductile, and low-cost material. It protects the thin primer layer from mechanical damage and chemical degradation. The primer layer protects the base material of the metallic component from oxidizing steam that may penetrate through cracks of the overlay layer. Due to suitable choice of coating materials and thicknesses of the layers the coating is low-cost.

  • Patent number: 6656606
    Abstract: The invention provides a pretreatment process for electroplating aluminum parts or strip, in which the zincating solution is modified to improve the adhesion of the subsequent electroplate to the substrate. The aluminum part or strip, such as an aluminum coin blank or strip for coin blanks, is pretreated with an improved zincate solution which provides hydroxide ions in an amount in the range of 75-175 gpl, zinc ions in an amount in the range of 15-40 gpl, nickel ions in an amount in the range of 2-10 gpl and copper ions in an amount in the range of 1.5-5 gpl. The pretreatment process preferably includes a copper strike applied from a copper cyanide strike bath at a pH in the range of 8.5-9.5, using a current density in the range of 0.1-10 A/dm2. The pretreatment and electroplating steps are preferably conducted by barrel plating, in accordance with another aspect of the invention.
