Abstract:
In a semiconductor device, the marginal edge of a resist member on the side closer to a substrate is between first and third positions on a metal base plate. The third position is directly under an outer side surface of a metal plate. The first position is outside the third position and is away from a second position on the metal base plate directly under an outer side surface of the electrical insulating board, by a distance calculated by dividing “the height from a principal surface of the metal base plate to the front surface of the electrical insulating board” by “the tangent of the contact angle of solder created by the marginal edge stopping solder flow”. This makes it possible to ensure sufficient insulation distances between conductive patterns and the solder and to reduce creepage distances of the conductive patterns over the electrical insulating board.

Claim (Index 2):
A semiconductor device comprising:\n a substrate having a front surface and a rear surface, and including\n a conductive pattern having a first side surface, \n an electrical insulating board having the conductive pattern on a front surface thereof, and having a second side surface parallel to the first side surface, and \n a metal plate disposed on a rear surface of the electrical insulating board, having a third side surface parallel to the first and second side surfaces, the metal plate having a size that is smaller than a size of the electrical insulating board in a plan view so that the electrical insulating board extends beyond the metal plate; \n a base plate having a principal surface to which the metal plate in the substrate is joined by a joining member; and a resist member formed in a stripe shape on the base plate in parallel to the first side surface in a plan view, wherein the base plate has first, second, and third positions defined thereon in a cross-sectional view, the first position being outwardly away from the third position, the second position being directly under the second side surface, the third position being directly under the third side surface, wherein the resist member has a marginal edge on a side closer to the substrate, and the marginal edge is located between the third position and the first position in the cross-sectional view, and wherein the first position is away from the second position by a distance calculated by multiplying \u201ca height from the principal surface of the base plate to the front surface of the electrical insulating board\u201d by \u221a{square root over (3)}.
