Wire Bonding For Semiconductor Devices
A semiconductor device includes an integrated circuit die having bond pads and a bond wires. The bond wires are connected to respective ones of the bond pads by a ball bond. An area of contact between the ball bond and the bond pad has a predetermined shape that is non-circular and includes at least one axis of symmetry. A ratio of the ball bond length to the ball bond width may be equal to a ratio of the bond pad length to the bond pad width.

MICRO-COAXIAL WIRE BONDING
A method includes attaching a micro-coaxial wire to electrical contacts in a substrate, the micro-coaxial wire including a core wire, a bonded section, and a shield layer, the electrical contacts including a first electrical contact and a second electrical contact. Attaching the micro-coaxial wire to the electrical contacts includes connecting a core wire of the micro-coaxial wire to the first electrical contact including forming a bonded section by bonding the core wire to the first electrical contact, and then depositing solder onto the bonded section of the core wire.
Wire bonding methods and systems incorporating metal nanoparticles
Wire bonding operations can be facilitated through the use of metal nanoparticle compositions. Both ball bonding and wedge bonding processes can be enhanced in this respect. Wire bonding methods can include providing a wire payout at a first location from a rolled wire source via a dispensation head, contacting a first metal nanoparticle composition and a first portion of the wire payout with a bonding pad, and at least partially fusing metal nanoparticles in the first metal nanoparticle composition together to form an adhering interface between the bonding pad and the first portion of the wire payout. The adhering interface can have a nanoparticulate morphology. Wire bonding systems can include a rolled wire source, a dispensation head configured to provide a wire payout, and an applicator configured to place a metal nanoparticle composition upon at least a portion of the wire payout or upon a bonding pad.
