Abstract
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.
