Abstract:
1. A method for fabricating a semiconductor device comprising the steps of: providing a plate having a flat surface and an opening to a recess in the surface, the opening having an outline suitable for enabling the insertion of a semiconductor chip, and the recess having a depth equal to a first portion of the chip thickness; providing a semiconductor chip having a first surface with terminals, an opposite second surface, and a thickness including a first and a remaining second portion; inserting the chip into the recess so that the first surface faces away from the recess and the second surface touches the recess, whereby the first thickness portion is inside the recess and the remaining second thickness portion projects from the opening; laying a flat metal leadframe on the plate, the leadframe having a plurality of leads surrounding the opening at a distance from the inserted chip, the leads held in place by the frame; connecting the chip terminals to the leads by spanning conductive wires across the distance; packaging the second thickness portion including the first surface and the terminals, the wires and the leads in an encapsulation compound, whereby the first thickness portion and the second surface remain un-packaged, and the leads do not project from the compound; lifting the package from the plate; and trimming the frame from the leads, thereby singulating the packaged device.
