Abstract:
A method for fabricating an electronic multi-output device. A substrate having a pad and pins is provided. A first chip is provided having a first and a second transistor integrated so that the first terminals of the transistors are merged into a common terminal on one chip surface and the patterned second and third terminals are on the opposite chip surface. The common first terminal is attached to the substrate pad. A driver and control chip is attached to the substrate pad adjacent to the first chip. The second terminals of the first and second transistors are connected by discrete first and second gang clips to respective substrate pins. A second chip is provided having a third and a fourth transistor integrated so that the second terminals of the transistors are merged into a common terminal on one chip surface. Patterned first and third terminals are on the opposite chip surface. The second chip is flipped to attach the first terminals vertically to the first and second gang clips. The third terminals are concurrently attached by discrete gang clips to respective pins. A common clip is attached to the common second terminal and connecting the common clip to a pin.
