ABSTRACT:
A hybrid IC with a semiconductor power device and a control circuit for controlling the power device being bare-chip mounted on a substrate includes a wiring arranged between a power source line and a gate of the power device whereby the wiring connects the power source line to the gate during a burn-in test and is cut off after the burn-in test. The hybrid IC preferably provides a wiring pattern for disconnecting the control circuit to the gate of the power device during a burn-in test which is shortcircuited after the burn-in test.
