  • Patent number: 7576297
    Abstract: A bonding apparatus including a capillary 40 having a high-frequency coil 50 on its tip end portion and allowing a bonding wire 2 to pass therethrough, a position changing unit for changing the position of the tip of the bonding wire, a gas supply unit for supplying gas into the capillary, and a high-frequency power supply unit for supplying high-frequency power to the high-frequency coil. When the bonding wire is outside a plasma region 52 in the capillary, a microplasma generated in the plasma region is ejected out of the capillary and removes foreign matter or contaminants on the surface of a bonding subject. When the bonding wire is inside the plasma region, the material of the bonding wire is turned into fine particles, and a microplasma 303 containing sputtered fine particles is ejected from the capillary, allowing the material the same as the bonding wire to be deposited on the bonding subject.

  • Patent number: 7370785
    Abstract: A wire bonding apparatus and method involving a computer 41 that has a height position counter 44 that produces height position signals for a capillary 5 by processing signals from a position sensor 29 that detects the position of the bonding arm 20 in the vertical direction. This computer 41 includes a memory 60, which stores the detected position of the capillary 5 at the time that secondary bonding is performed on a bump that is formed in a normal manner on the second conductor, and a comparator circuit 61, which outputs a “bump not-adhered” signal in cases where the output value of the height position counter 44 is outside the permissible error range of the detected position that is stored in the memory 60.
