Abstract: A power supply module includes a metallic clip including a plate having an area and a first and a second ridge on opposite sides of the plate. The ridges bent in the same direction away from the plate. The first and the second ridges conductively attached to the substrate, where the substrate is of insulating material integral with metal traces, the plate roofing over the substrate between the ridges. A first MOS field-effect transistor (FET) chip and, horizontally side-by-side, a second MOSFET chip are attached and wire bonded to the substrate under the plate. The drain of the first MOSFET is connected to the input terminal of the module, the source of the first MOSFET is tied to the drain of the second MOSFET, and the source of the second MOSFET, together with the second ridge, is connected to ground. A driver and controller chip is attached to the substrate under the plate and wire bonded to the gates of the first and second MOSFET. A capacitor is attached to the substrate under the clip plate and conductively connected to the first clip ridge and to the drain of the first MOSFET.

Abstract: A method for fabricating packaged semiconductor devices (100) with an open cavity (110a) in panel format; placing (process 201) on an adhesive carrier tape a panel-sized grid of metallic pieces having a flat pad (230) and symmetrically placed vertical pillars (231); attaching (process 202) semiconductor chips (101) with sensor systems face-down onto the tape; laminating (process 203) and thinning (process 204) low CTE insulating material (234) to fill gaps between chips and grid; turning over (process 205) assembly to remove tape; plasma-cleaning assembly front side, sputtering and patterning (process 206) uniform metal layer across assembly and optionally plating (process 209) metal layer to form rerouting traces and extended contact pads for assembly; laminating (process 212) insulating stiffener across panel; opening (process 213) cavities in stiffener to access the sensor system; and singulating (process 214) packaged devices by cutting metallic pieces.
