SEMICONDUCTOR MODULE AND METHOD FOR MANUFACTURING SEMICONDUCTOR MODULE
There are provided a semiconductor module capable of preventing the peeling of a sealing resin on the side where a connection section used for the connection to a semiconductor element is arranged and a manufacturing method for a semiconductor module. 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 through holes where sealing resins are formed, the sealing resins connecting adjacent housing sections and the sealing resin formed in the through hole being continuous with the sealing resins formed in the housing sections.
Enhanced systems and methods for improved heat transfer from semiconductor packages
Enhanced thermal energy transfer systems for semiconductor packages are provided. A thermally conductive member is disposed in the interstitial space between an upper surface of a semiconductor package and a lower surface of a thermal member. The thermally conductive member is disposed above a first portion of the upper surface of the semiconductor package having a relatively higher thermal energy output when the semiconductor package is operating. A thermal interface material is disposed in the interstitial space and a force applied to the thermal member. The thermally conductive member forms a relatively higher pressure region above the first portion of the semiconductor package and a relatively lower pressure region in other portions of the semiconductor package remote from the thermally conductive member. The increased pressure region proximate the thermally conductive member beneficially enhances the flow of thermal energy from the first portion of the semiconductor package to the thermal member.
Power Semiconductor Device and Method of Manufacturing the Same, and Power Conversion Device
A power semiconductor device in which the size of an insulating substrate is reduced and connection failure can be suppressed includes an insulating substrate, a semiconductor element, and a printed circuit board. The semiconductor element is bonded to one main surface of the insulating substrate. The printed circuit board is bonded to face the semiconductor element.

A power module includes an insulating substrate, a case member, a power semiconductor element, a base member, a sealing member, and an adhesive member. The insulating substrate has a first surface and a second surface opposite to the first surface. The case member surrounds the insulating substrate when viewed in a direction perpendicular to the first surface. The power semiconductor element faces the first surface.

The adhesive member fixes the base member and the case member, and surrounds the insulating substrate when viewed in the direction perpendicular to the first surface.
SEMICONDUCTOR PACKAGING
Disclosed is a semiconductor packaging. The semiconductor packing comprises a substrate on which a semiconductor device is arranged on a front surface; a channel member disposed on a rear surface of the substrate and forming a cooling flow path through which a refrigerant moves; and a porous diamond layer covering an outer surface of the channel member.
Thermally Enhanced FCBGA Package
A semiconductor device has a heat spreader with an opening formed through the heat spreader. The heat spreader is disposed over a substrate with a semiconductor die disposed on the substrate in the opening. A thermally conductive material, e.g., adhesive or an elastomer plug, is disposed in the opening between the heat spreader and semiconductor die. A conductive layer is formed over the substrate, heat spreader, and thermally conductive material.
SEMICONDUCTOR DEVICE AND MANUFACTURING METHOD THEREFOR
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.
