ABSTRACT:
A resin-coated, bonding fine wire for use in forming bonded electrical connections on a semiconductor device, wherein the wire is characterized as having a tensile strength exceeded when the wire is further elongated in length in a range of 0.5% to 3.5% of its original length by breaking of the wire during tension testing. It has been determined that an insulated bonding fine wire exhibiting such relatively low ductility produces a loop profile maintainable in a stable condition during a bonding operation while providing reliable bonding strength.
