Abstract
Disclosed is a wirebond pin having a star-shaped anchor, collar and paddle. The collar prevents passivation material, used to make a sealed semiconductor device, from leaking out of the package. The collar also helps to eliminate the resonant vibration of the pin during ultrasonic wirebonding at the paddle.
