Semiconductor device comprising PN junction diode and schottky barrier diode
A semiconductor device includes a MOSFET including a PN junction diode. A unipolar device is connected in parallel to the MOSFET and has two terminals. A first wire connects the PN junction diode to one of the two terminals of the unipolar device. A second wire connects the one of the two terminals of the unipolar device to an output line, so that the output line is connected to the MOSFET and the unipolar device via the first wire and the second wire. In one embodiment the connection of the first wire to the diode is with its anode, and in another the connection is with the cathode.

SEMICONDUCTOR MODULE AND SEMICONDUCTOR PACKAGE
A semiconductor module includes: a control circuit for controlling first and second transistors operating complementarily; and an internal controller receiving a data signal including a set value of an operating characteristic from an external controller to store the data signal in a memory and then transferring the set value of the operating characteristic to the control circuit. The data signal is sent to the internal controller in the order of the set value of the operating characteristic and a specific trigger value. The internal controller transfers the set value of the operating characteristic to the control circuit in timed relation to writing of the specific trigger value into the memory. The control circuit includes first and second drivers. The control circuit changes settings of the first and second drivers to thereby change the operating characteristic of the semiconductor module.

METHOD OF MANUFACTURING SEMICONDUCTOR DEVICE
A flat plate frame is formed, which is flat plate-shaped, which has an opening penetrating its front and rear surfaces and groove terminal patterns formed on its front surface, and which contains a semi-cured thermosetting resin. Then, an insulating substrate is disposed on the rear surface so as to cover the opening of the flat plate frame, external connection terminals are disposed on the terminal patterns, and heating is carried out. As a result, a terminal package to which the insulating substrate and external connection terminals are firmly joined is produced using the flat plate frame. The external connection terminals included in the terminal package are reliably and firmly joined to the terminal package. Therefore, the external connection terminals are not displaced when wires are bonded to the external connection terminals.
