Abstract
A semiconductor device includes a power supply semiconductor chip that has a plurality of current passing electrodes and a plurality of control electrodes. Conductive plates are disposed on the current electrodes and the control electrodes, and extend to regions for external connections. The conductive plates also includes connecting regions that are suspended between the chip and the external connection regions and suppers vibration propagating to the chip. One conductive plate unit for the current passing electrodes and another conductive plate unit for the control electrodes are separately soldered on the corresponding electrodes. Alternatively, only one unit may be soldered on the semiconductor chip, and portions of the unit may be removed to fabricate the device. Because of the absence of wire-bonding steps, the semiconductor chip does not receive impact of wire-bonding during the manufacturing process.
