  • Publication number: 20090134036
    Abstract: An electrolytic processing method makes it possible to preferentially process a diffusion barrier layer while suppressing processing of an interconnect metal, thereby enabling omission of CMP or a lowering of processing pressure in CMP. The electrolytic processing method comprises: bringing a surface of a substrate (W) into contact with an electrolytic solution (48) comprising an organic solvent, such as propylene carbonate, and an electrolyte, such as lithium hexafluorophosphate, dissolved into the organic solvent, and optionally an inhibitor composed of a heterocyclic compound; and applying an electric potential, for example, a positive electric potential which is controlled at a value less than the decomposition voltage of the organic solvent, to the surface of the substrate (W) to carry out electrolytic processing of the substrate surface.

  • Publication number: 20090057159
    Abstract: Bipolar current electrodeposits a nanocrystalline grain size. Polarity Ratio relates the absolute value of time integrated amplitude of negative polarity and positive polarity current. Grain size can be controlled in alloys of two or more components, one of which being a metal, and one of which being most electro-active. Typically the more electro-active material is preferentially lessened in the deposit during negative current. The deposit is relatively crack and void free. Grain size is typically a function of deposit composition, which is typically a function of Polarity Ratio. Specified grain size can be achieved by selecting a corresponding Polarity Ratio. Coatings can be in layers, each having a grain size, which can vary layer to layer and also in a graded fashion. A finished article may be built upon a substrate of electro-conductive plastic, or metal, including steels, aluminum, brass. The substrate may remain, or be removed.

  • Patent number: 7459198
    Abstract: An electroplated film is deposited over a substrate with a plating frame pattern that includes a plating field defined by a plurality of individual features. By dividing the plating field into a plurality of individual features, the delamination force at any location on the plating field is greatly reduced. Thus, a film with a large stress, such as a high moment film, may be plated to a greater thickness than is possible with conventionally plated films.

A metallurgical bond has been formed between the layers. Thereby oxidation of the refractory metal layer, and thereby passivation of the object, can be avoided even with small amounts of precious metal. This lowers the material costs while ensuring desired corrosion resistant properties. The object is suitable for an electrode to be used in a corrosive environment, in particular when a large conductivity is needed. Also a method of manufacturing the object. The metallurgical bond is provided by heating the object.

    Abstract: Disclosed are embodiments of an electroplating system and an associated electroplating method that allow for depositing of metal alloys with a uniform plate thickness and with the means to alter dynamically the alloy composition. Specifically, by using multiple anodes, each with different types of soluble metals, the system and method avoid the need for periodic plating bath replacement and also allow the ratio of metals within the deposited alloy to be selectively varied by applying different voltages to the different metals. The system and method further avoids the uneven current density and potential distribution and, thus, the non-uniform plating thicknesses exhibited by prior art methods by selectively varying the shape and placement of the anodes within the plating bath. Additionally, the system and method allows for fine tuning of the plating thickness by using electrically insulating selectively placed prescribed baffles.

  • Patent number: 6852210
    Abstract: To provide a plating method, which enables wide industrial use of the redox system electroless plating method having excellent characteristics, and a plating bath precursor which is preferable for the plating method. The plating method comprises a process oxidizing first metal ions of a redox system of a plating bath from a lower oxidation state to a high oxidation state, and second metal ions of said redox system are reduced and deposited onto the surface of an object to be plated, wherein a process is provided in which by supplying the electrical current to the plating bath, the first metal ions are reduced from said lower oxidation state to thereby activate the plating bath. The plating bath precursor is formed stabilizing the plating bath so that reduction and deposition of the second metal ions substantially do not occur in order to improve its storing performance.

  • Publication number: 20040241833
    Abstract: The invention concerns a method wherein the substrate (5) to be coated is immersed in an autocatalytic chemical deposit bath (4), for example nickel, contained in a stainless steel vessel (1) and wherein can be optionally mixed a suspended MCrAlY alloy, so as to form a metal deposit (nickel) wherein are optionally included powder particles. The invention is characterised in that, to provide a prolonged operation of the bath, it consists in measuring with a voltmeter (8) the difference of potential between the substrate (5) and a reference electrode (6) immersed in the bath (4), and in imposing between the substrate (5) and the vessel (1) an electric current produced by a generator (10), said current being adjusted by a regulator (11) so as to maintain said potential difference at a selected value.

  • Patent number: 6805786
    Abstract: A relatively simple and inexpensive process for plating precious alloyed metals, such as AuSn, AuSnIn, AgSn, AuIn and AgIn. Anodes are formed from each of the metal components in the alloy and disposed in a conducting solution. The mass of each metal components is determined by Faraday's law. The target is also disposed in the conducting solution. Plating current is independently applied to each anode. The plating is conducted under an ultraviolet light sources to optimize the process. The plating alloys can be used for various purposes including attaching a semiconductor die to a substrate. Since the process does not involve exposure of the semiconductor die to a relatively high temperature for a relatively long time, the process does not pose a risk of contamination of the semiconductor by the adhesive or wax used to hold the die in place on the carrier during processing.
