A semiconductor module includes a first power semiconductor device, a conductive wire, and a resin film. The conductive wire is joined to a surface of a first front electrode of the first power semiconductor device. The resin film is formed to be continuous on at least one of an end portion or an end portion of a first joint between the first front electrode and the conductive wire in a longitudinal direction of the conductive wire, a surface of the first front electrode, and a surface of the conductive wire. The resin film has an elastic elongation rate of 4.5% to 10.0%.

Semiconductor module and power conversion apparatus

The conductive wire is bonded to the front electrode of the semiconductor device at the bonding section. The first resin member covers at least one end portion of two end portions of the bonding section, the first surface of the front electrode, and the second surface of the conductive wire. The second resin member covers the bent portion of the first resin member. The first resin member has a higher break elongation and a higher break strength than the second resin member. The second tensile elastic modulus of the second resin member is greater than the first tensile elastic modulus of the first resin member. Thereby, the reliability of the power semiconductor module is improved.

Power semiconductor module and power converter

A power module which inhibits disjoin between a sealing resin and an adhesive. The power module includes: an insulative substrate having a semiconductor element mounted on the top surface; a base plate joined to the rear surface of the insulative substrate; a case member with the base plate, that surrounds the insulative substrate, the case member having a bottom surface whose inner periphery portion side being in contact with a top surface of the base plate, the bottom surface being provided with an angled surface whose distance to the top surface of the base plate increases toward an outer periphery side of the base plate; an adhesive member filled between the base plate and the angled surface to adhere the base plate and the case member; and a filling member filled in a region bounded by the base plate and the case member.
