摘要: There is provided a semiconductor module capable of preventing the peeling of a sealing resin on the side where connection sections used for the connection to semiconductor elements are arranged. A semiconductor module includes: an outer frame; sealing resins; gate signal output terminals, and partition sections laid across the outer flame to partition a space into a plurality of housing sections, in the partition sections which the gate signal output terminals with connection sections exposed are arranged. The partition sections have first surface sections on the side where the connection sections are arranged and second surface sections formed, on the side where the connection sections are not arranged, such that the peeling strength to the sealing resins is lower than that of the first surface sections.

摘要: A semiconductor device includes a baseplate and a case which includes an external wall surrounding an internal space and a dividing wall extending in a first direction and separating the space into compartments. The dividing wall has a lower end fixed to the principal surface and includes, on a sidewall, a terrace positioned further away from the principal surface than the lower end and hanging out toward the space compared to the lower end in a second direction parallel to the principal surface and perpendicular to the first direction. A terminal's bonding part, to which a wire is bonded, is disposed on the terrace. A ratio of the wire's diameter to the bonding part's width in the first direction is set to ≤0.15, which prevents a situation where bonding power is not sufficiently applied to the bonding part during ultrasonic bonding of the wire, thus increasing the bonding strength.

摘要: A conductive member constituting a wiring structure includes a first bonding section bonded to an electronic component, a second bonding section bonded to a connection target for the electronic component, and a raised section that protrudes upward from the first bonding section and is connected to the second bonding section. The conductive member has a wire member passage through which a wire member passes, and which is provided in at least a part of the raised section. The wire member passage enables the wire member to be disposed along the raised section from the first bonding section to the second bonding section such that the wire member intersects a surface of the raised section.
