Abstract
A package for power semiconductor components permitting high thermal dissipation and current conductance and including a frame assembly bonded to a substrate on which a power semiconductor chip is mounted. The frame assembly has a wirebonding grid for connecting short, uniform length wirebonds to the surface of the chip. The grid is configured so as to have a portion overlaying and spaced from the chip a distance less than a distance required to connect a wirebond of optimal length to each anode cell of the chip. The package allows a high power semiconductor device to be used as a surface mount device or as a hockey puck.
