Abstract
There is provided a power semiconductor module with multiple semiconductor chips arranged in parallel on an insulated substrate, allowing for high density mounting of semiconductor chips and highly reliable with less difference in operating characteristics from one semiconductor chip to another. The above module includes an insulated substrate; a first conductive pattern laid out on the insulated substrate; multiple power semiconductor chips arranged on the first conductive pattern; a first wiring formed to bridge and directly connecting respective gate electrodes of the power semiconductor chips; and a second wiring formed to bridge and directly connecting respective source electrodes of the power semiconductor chips, wherein the first wiring is placed alongside of the second wiring and may be angled within 30 degrees with respect to the second wiring.
