Abstract: A ribbon, preferably a bonding ribbon for bonding in microelectronics, contains a first layer containing copper, a coating layer containing aluminum superimposed over the first layer, and an intermediate layer. In a cross-sectional view of the ribbon, the area share of the first layer is from 50 to 96% and the aspect ratio between the width and the height of the ribbon in a cross-sectional view is from 0.03 to less than 0.8. The ribbon has a cross-sectional area of 25,000 μm2 to 800,000 μm2. The intermediate layer contains at least one intermetallic phase containing materials of the first and coating layers. The invention further relates to a process for making a wire, to a wire obtained by the process, to an electric device containing the wire, to a propelled device comprising said electric device and to a process of connecting two elements through the wire by wedge-bonding.

Abstract: Wafers include multiple bulk redistribution layers. A terminal contact pad is on a surface of one of the bulk redistribution layers. A final redistribution layer is formed on the surface and in contact with the terminal contact pad. The final redistribution layer is formed from a material other than a material of the plurality of bulk redistribution layers. A solder ball is formed on the terminal contact pad.

Abstract: A wire, preferably a bonding wire for bonding in microelectronics, contains a copper core with a surface and coating layer containing aluminum superimposed over the surface of the copper core. The ratio of the thickness of the coating layer to the diameter of the copper core is from 0.05 to 0.2 μm. The wire has a diameter in the range of from 100 μm to 600 μm and specified standard deviations of the diameter of the copper core and of the thickness of the coating layer. The invention further relates to a process for making a wire, to a wire obtained by the process, to an electric device containing at least two elements and the wire, to a propelled device containing the electric device, and to a process of connecting two elements through the wire by wedge bonding.

Abstract: Wafers and methods of forming solder balls include forming a final redistribution layer over terminal contact pad on a surface of a wafer. The wafer includes multiple bulk redistribution layers. A hole is etched in the final redistribution layer to expose the terminal contact pad. Solder is injected into the hole using an injection nozzle that is in direct contact with the final redistribution layer. The final redistribution layer is etched back. The injected solder is reflowed to form a solder ball.

Abstract: A semiconductor device includes a semiconductor element that is mounted on a substrate, an electrode pad that contains aluminum as a main component and is provided in the semiconductor element, a copper wire that contains copper as a main component and connects a connection terminal provided on the substrate and the electrode pad, and an encapsulant resin that encapsulates the semiconductor element and the copper wire. When the semiconductor device is heated at 200° C. for 16 hours in the atmosphere, a barrier layer containing any metal selected from palladium and platinum is farmed at a junction between the copper wire and the electrode pad.
