Wire bonding is the method of making interconnections between an integrated circuit (IC) or other semiconductor device and its packaging during semiconductor device fabrication. Although less common, wire bonding can be used to connect an IC to other electronics or to connect from one printed circuit board (PCB) to another. Wire bonding is generally considered the most cost-effective and flexible interconnect technology and is used to assemble the vast majority of semiconductor packages. Wire bonding can be used at frequencies above 100 GHz.

Aluminum wire bonding is a process similar to gold wire bonding but with the critical distinction that the surface does not need to be heated to 150°C or even anything above room temperature. Force and ultrasonics are vital to the formation of aluminum bonds. The creation of an aluminum wire bond is the same as for gold wire, which consists of two attachment points and a specific loop shape. During the attachment steps for the wire, the only factors needed for the bond are force and ultrasonics, as the surface does not need to be heated.

Aluminum bonding wire, like gold wire, provides a strong electrical path for connections between components in an assembly but has some key advantages. Aluminum bonding allows for interconnections to be formed on temperature-sensitive assemblies where the materials cannot withstand the temperatures usually required for gold bonding. Aluminum wire is also much preferred over gold wire on Aluminum surfaces in hermetically sealed packages as the temperatures needed for hermetic sealing can compromise the integrity of Au on Al bonds.
