  • Patent number: 11594503
    Abstract: A wire bonding method includes bonding a tip of a wire provided through a clamp and a capillary onto a bonding pad of a chip, moving the capillary to a connection pad of a substrate corresponding to the bonding pad, bonding the wire to the connection pad to form a bonding wire connecting the bonding pad to the connection pad, before the capillary is raised from the connection pad, applying a electrical signal to the wire to detect whether the wire and the connection pad are in contact with each other, changing a state of the clamp to a closed state when the wire is not in contact with the connection pad and maintaining the state of the clamp in an open state when the wire is in contact with the connection pad, and raising the capillary from the connection pad while maintaining the state of the clamp.

  • Publication number: 20190157237
    Abstract: A semiconductor device includes a first device having a first pad; a second device having a second pad; and a bonding wire electrically connecting the first device and the second device to each other via the first pad and the second pad. The bonding wire includes: a first bonding structure provided at a first end of the bonding wire, electrically connected to the first device and includes: a first ball bonding region; and a first stitch bonding region; and a second bonding structure provided at a second end opposite of the first end of the bonding wire and electrically connected to the second device.
