Semiconductor module

A semiconductor module comprising:

• first to fourth semiconductor chips;
• first to fifth wiring patterns;
• a first power source terminal;
• one second power source terminal;
• an other second power source terminal;
• and a first intermediate point terminal and a second intermediate point terminal thus forming a bridge circuit in the semiconductor module, wherein,
• the bridge circuit is formed where the first semiconductor chip and the third semiconductor chip are chips disposed on a high side, and the second semiconductor chip and the fourth semiconductor chip form chips disposed on a low side, wherein
• the first semiconductor chip and the third semiconductor chip are disposed in symmetry with respect to a center line, the second semiconductor chip and the fourth semiconductor chip are disposed in symmetry with respect to the center line, the first wiring pattern and the third wiring pattern are disposed in symmetry with respect to the center line, and the second wiring pattern and the fourth wiring pattern are disposed in symmetry with respect to the center line, the first intermediate point terminal and the second intermediate point terminal are disposed in symmetry with respect to the center line, and the one second power source terminal and the other second power source terminal are disposed in symmetry with respect to the center line,
• the fifth wiring pattern and the first power source terminal are respectively disposed in symmetry with respect to the center line,
• the first intermediate point terminal and the second intermediate point terminal are disposed adjacently to each other on one side of the semiconductor module,
• the first power source terminal, the one second power source terminal and the other second power source terminal are disposed on an other side of the semiconductor module, and
• the first power source terminal is disposed in a space above the fifth wiring pattern in a non-contact state and connects the first wiring pattern and the third wiring pattern to each other.
