Abstract

See full text

Microfeature workpieces having alloyed conductive structures, and associated methods are disclosed. A method in accordance with one embodiment includes applying a volume of material to a bond pad of a microfeature workpiece, with the volume of material including a first metallic constituent and the bond pad including a second constituent. The method can further include elevating a temperature of the volume of material while the volume of material is applied to the bond pad to alloy the first metallic constituent and the second metallic constituent so that the first metallic constituent is alloyed generally throughout the volume of material. A thickness of the bond pad can be reduced from an initial thickness T1 to a reduced thickness T2.
