Patent number: 6972081Abstract: A process for fabricating a vertical spiral inductor within a multichip module package is disclosed. The process consists of depositing a pattern of bottom lines by electroplating copper on a substrate and then depositing an insulation pattern. Next, depositing a pattern of permeable material to form a core and then depositing polyimide to define vias and permeable core insulation. The vias are filled by electroplating copper. The vertical spiral inductor is formed and defined by next depositing a pattern of top metal (e.g. copper) lines by electroplating wherein the top metal lines are staggered with respect to the bottom metal lines. Lastly a top protective layer is deposited. The core is made from a permeable or non-permeable material.Type: GrantFiled: February 5, 2003Date of Patent: December 6, 2005Assignee: Xerox CorporationInventor: Kaiser H. Wong

Patent number: 6821879Abstract: The invention is directed to a fabrication method of copper interconnects using dual damascene processing. Using silicon to provide an active surface, palladium can be selectively deposited on silicon by an immersion plating technique. After palladium deposition (about 1000 Å thick), either a layer of cobalt phosphorus or alloy cobalt/nickel phosphorus or nickel phosphorus is deposited on the palladium layer using an electroless plating technique. This cobalt phosphorus, cobalt/nickel phosphorus alloy, or nickel phosphorus layer serves as a copper diffusion barrier. The via and trenches are filled with copper by an electroless copper plating method and CMP is used to remove the excess copper and planarize-/-polish the copper/dielectric surface.Type: GrantFiled: October 30, 2002Date of Patent: November 23, 2004Assignee: Xerox CorporationInventor: Kaiser H.
