Abstract:
A method of forming a bond between a wire and a semiconductor device at a bond site thereon, comprising:(a) feeding said wire through a capillary having a lumen adapted to receive said wire therethrough such tat a distal end of said wire extends out of a bonding end of said capillary; (b) forming a ball on said distal end of said wire; (c) bringing said ball into contact with said semiconductor device at said bond site; (d) generating ultrasonic vibration energy; (e) applying a first portion of said ultrasonic vibration energy directly to said capillary in a first direction; (f) redirecting a second portion of said ultrasonic vibration energy along a medium capable of transmitting said ultrasonic vibration energy; (g) applying said second portion of said ultrasonic vibration to said capillary in a second direction different than said first direction.
