A wire bonding tool for bonding a micro-coaxial wire to a bonding surface includes an electrical-energy application mechanism configured to apply electrical-energy to remove a portion of an electrically conductive shield layer of the micro-coaxial wire to expose a portion of an insulating layer of the micro-coaxial wire, a thermal-energy application mechanism configured to apply thermal-energy to the micro-coaxial wire to remove the exposed portion of the insulating layer of the micro-coaxial wire to expose a portion of a core wire of the micro-coaxial wire, and a bonding head configured to bond the exposed portion of the core wire of the micro-coaxial wire to the bonding surface.

The present disclosure provides a wire bonding apparatus, a wire bonding method and a semiconductor device. The wire bonding apparatus includes: a wire tube for containing the wire and including a wire exit; a wire heating assembly located at a side of the wire exit; and a pre-shaping assembly located at a side of the wire tube and including a wire pre-pressing face; the pre-shaping assembly having a first state in which the wire pre-pressing face of the pre-shaping assembly is configured to abut the wire tube and a second state in which the pre-shaping assembly is configured to disengage from the wire tube. The wire bonding apparatus, the wire bonding method and the semiconductor device as provided in the present disclosure can reduce or eliminate the cratering effect.
