Abstract:
An insulating gate semiconductor device includes an insulating gate semiconductor element, an insulating circuit board, and a main-current path member. A main-current of the insulating gate semiconductor element flows toward a first external terminal in the main-current path member; and a gate-current path member, being patterned so as to have a linearly extending portion arranged in parallel to a linearly extending portion of the main-current path member in a planar pattern on the insulating circuit board, being provided to connect between a second external terminal and a gate electrode of the insulating gate semiconductor element. A current which is induced in the gate-current path member by mutual induction caused by a change in magnetic field implemented by the main-current is used for increasing the gate-current in a turn-on period of the insulating gate semiconductor element.

Claim (Index 1):
An insulating gate semiconductor device comprising:\n an insulating gate semiconductor element, being a semiconductor chip; an insulating circuit board, having a first external terminal and a second external terminal provided in a periphery of the insulating circuit board, the semiconductor chip is mounted on the insulating circuit board; a main-current path member, being patterned so as to have a linearly extending portion in a planar pattern on the insulating circuit board, being provided to connect between the first external terminal and a main electrode region of the insulating gate semiconductor element, and a main-current of the insulating gate semiconductor element flows toward the first external terminal in the main-current path member; and a gate-current path member, being patterned so as to have a linearly extending portion arranged in parallel to the linearly extending portion of the main-current path member in a planar pattern on the insulating circuit board, being provided to connect between the second external terminal and a gate electrode of the insulating gate semiconductor element, and a gate-current which controls the main-current flow in a direction opposite to the main-current in the portion arranged in parallel in the gate-current path member, wherein a current which is induced in the gate-current path member by mutual induction caused by a change in magnetic field implemented by the main-current is used for increasing the gate-current in a turn-on period of the insulating gate semiconductor element.
