Semiconductor device having terminals directly attachable to circuit board
Disclosed embodiments relate to a semiconductor device. A semiconductor device is fabricated by attachment of a first chip to a first surface of a pad of a leadframe. Each of one or more terminals of the first chip is connected to a respective lead of the leadframe. The first chip and the first surface of the pad are then encapsulated in a packaging material, while leaving an opposite second surface of the pad exposed. A second chip is attached to a recessed portion of the second surface of the pad so that at least one terminal of the second chip is substantially coplanar with an un-recessed portion of the second surface. In one embodiment, a third chip is also attached to the recessed portion of the second surface so that at least one terminal of the third chip is substantially coplanar with the un-recessed portion of the second surface.
Semiconductor module
A semiconductor module includes a semiconductor element having one and the other surface, a lead terminal connected electrically and thermally to the semiconductor element, a first solder which bonds the lead terminal and the one surface of the semiconductor element together, a circuit layer over which the semiconductor element is disposed and a second solder which bonds the other surface of the semiconductor element and the circuit layer together. The inequality
(A/B)<1 holds, where A and B are the tensile strength of the first and second solder, respectively. As a result, even if the lead terminal which thermally expands because of heat generated by the semiconductor element expands or contracts toward the semiconductor element, a stress applied by the lead terminal is absorbed and relaxed by the first solder. This prevents damage to the surface electrode of the semiconductor element by suppressing the occurrence of cracks.
