摘要： 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.

摘要： A multilayer ceramic repair process which provides a new electrical repair path to connect top surface vias. The repair path is established between a defective net and a redundant repair net contained within the multilayer ceramic substrate. The defective net and the repair net each terminate at surface vias of the substrate. A laser is used to form post fired circuitry on and in the substrate. This is followed by the electrical isolation of the defective net from the electrical repair structure and passivation of the electrical repair line.

摘要： An electroless Cu layer is formed on each side of a packaging substrate containing a core, at least one front metal interconnect layer, and at least one backside metal interconnect layer. A photoresist is applied on both electroless Cu layers and lithographically patterned. First electrolytic Cu portions are formed on exposed surfaces of the electroless Cu layers, followed by formation of electrolytic Ni portions and second electrolytic Cu portions. The electrolytic Ni portions provide enhanced resistance to electromigration, while the second electrolytic Cu portions provide an adhesion layer for a solder mask and serves as an oxidation protection layer. Some of the first electrolytic Cu may be masked by lithographic means to block formation of electrolytic Ni portions and second electrolytic Cu portions thereupon as needed. Optionally, the electrolytic Ni portions may be formed directly on electroless Cu layers.
