A semiconductor component including: a substrate, at least one semiconductor chip arranged on the substrate and at least one passive device likewise arranged on the substrate. The passive device is mounted with its underside on the substrate. The semiconductor component further includes an interspace disposed between the underside of the passive device and the substrate. The interspace is filled with an underfilling material. In order to avoid the solder pumping effect, the upper side and the lateral sides of the passive device are also embedded in a plastic compound.

A semiconductor device includes a plastic housing and a semiconductor chip, wherein the semiconductor chip includes an active top side and a rear side. An interposer is arranged on the active top side of the semiconductor chip. At least a portion of the interposer is embedded into the plastic housing, while the top side of the interposer forms the top side of the semiconductor device. A top side fitting shape is arranged on the top side of the interposer, where the top side fitting shape has a predetermined radius of curvature that is free of plastic housing composition, and the top side fitting shape has a convex or concave lens-shaped sphere segment shape.

A method of assembling a semiconductor device includes providing a chip attached to an elastic carrier, and supporting the elastic carrier with a stiffener. The method additionally includes removing the stiffener from the elastic carrier after attaching the elastic carrier to a board.

Semiconductor device

A semiconductor module and a method for producing the same is disclosed. In one embodiment, the semiconductor module has adjacent regions on a common wiring substrate in a common plastic housing composition. The regions are thermally decoupled by a thermal barrier. Semiconductor chips whose evolution of heat loss differs are arranged in these thermally separate regions, the thermal barrier ensuring that the function of the more thermally sensitive semiconductor chip is not impaired by the heat-loss-generating semiconductor chip.

A heat sink for surface-mounted semiconductor devices is provided on a superordinate circuit board of an electronic module. The heat sink includes a three-dimensionally structured thermally conductive plate with a press-on region and snap-action hooks. The snap-action hooks are arranged approximately at right angles with respect to the press-on region and are spring-elastically connected to the press-on region of the heat sink via a spring-elastic connecting region of the heat sink. The snap-action hooks engage with edge regions of a thermally conductive coupling plate with the press-on region generating pressure. The coupling plate is fixed to a rear side of a semiconductor chip of the surface-mounted semiconductor device.

A semiconductor assembly includes a module holder and a semiconductor module, which has a board substrate with conductor tracks and one or more unpackaged semiconductor chips mounted on the substrate, which are connected to conductor tracks on the substrate by electrical contacts. The substrate has at one edge at least one contact strip with connection contact areas, which are connected to at least some of the conductor tracks. The module holder has a plug-in connection for the electrical connection to other components, at least one mating contact strip for the connection to the contact strip of the at least one semiconductor module and electrical conductors between the contact areas of the at least one semiconductor module and electrical contacts of the plug-in connection. The configuration allows semiconductor modules to be connected to the outside world in an economical way.
