    Abstract: A method of making a semiconductor device includes separating a conductive structure of a leadframe into interior conductive leads using an etching process. The method includes forming a first molded structure by applying a first molding compound to a leadframe having a conductive structure, separating the conductive structure into at least two interior contact portions, attaching a semiconductor die to at least one of the interior contact portions, the at least two interior contact portions being supported by the first molding compound, and forming a second molded structure by applying a second molding compound to at least part of the semiconductor die and at least two interior contact portions.

    Abstract: A packaged transistor device (100) comprises a semiconductor chip (101) including a transistor with terminals distributed on the first and the opposite second chip side; and a slab (110) of low-grade silicon (l-g-Si) configured as a ridge (111) framing a depression including a recessed central area suitable to accommodate the chip, the ridge having a first surface in a first plane and the recessed central area having a second surface in a second plane spaced from the first plane by a depth (112) at least equal to the chip thickness, the ridge covered by device terminals (120; 121) connected to attachment pads in the central area having the terminals of the first chip side attached so that the terminals (103) of the opposite second chip side are co-planar with the device terminals on the slab ridge.
