Patent ID: 7504733

Claim:
A clip-less packaged semiconductor device, said packaged semiconductor device having top and bottom surfaces and side surfaces therebetween, comprising: at least one semiconductor die, said die having a bottom surface and a top surface, said bottom surface having at least one electrode, said top surface having at least one electrode; a leadframe, said leadframe comprising a sheet of conductive material having top and bottom surfaces, said top surface being substantially planar, said bottom surface having a recessed region having a thickness less than the thickness of said sheet of conductive material formed in said sheet and defining a plurality of planar lead contacts; wherein said die is electrically coupled to said leadframe with said top surface of said die electrically coupled to the bottom surface of said leadframe in said recessed region; and an encapsulating layer, said encapsulating layer partially enclosing said leadframe and die, wherein said encapsulating layer occupies portions of said recessed region not occupied by said die, wherein said bottom surface of said die and said plurality of planar lead contacts are exposed through said encapsulating layer, at said bottom surface of said packaged semiconductor device.
