Abstract: A semiconductor module includes: a wiring board including a ceramic substrate and conductor patterns on a first surface of the ceramic substrate; a semiconductor element arranged on at least one of the conductor patterns on the first surface of the ceramic substrate; a sealing insulator that seals the wiring board and the semiconductor element; and an insulating member disposed on the first surface of the ceramic substrate in a gap between the conductor patterns that are adjacent to each other, the insulating member extending in an extending direction of the gap and dividing an area in the gap where the sealing insulator fills the gap so that the insulating member is separate from respective edges of the conductor patterns adjacent to each other.

Abstract: A semiconductor device, including a semiconductor chip having a first electrode on a rear surface thereof, a laminated substrate including a heat dissipation board laminated on a rear surface of an insulating board, and a case. The case includes a frame surrounding an opening penetrating the case from a front surface to a rear surface thereof, the frame being in contact with a periphery of the laminated substrate covering the opening from the rear surface of the case, and a first terminal penetrating the frame. The first terminal includes a first connection part penetrating the frame and extending out of the frame, and a first wiring part provided in the opening. The first wiring part has a wiring rear surface disposed on a front surface of the insulating board, and a wiring front surface mechanically and electrically connected to the first electrode of the semiconductor chip.
