Abstract:
1. A packaged leadless semiconductor device comprising: a heat sink flange having an upper surface and a lower surface spaced apart by a flange thickness; a semiconductor die physically coupled to said upper surface of said heat sink flange; a frame structure having a perimeter that defines a cavity and terminal pads surrounding said cavity, each of said terminal pads including a first surface and a second surface, said first surface being spaced apart from said second surface by a distance that is greater than said flange thickness, and said heat sink flange is positioned in said cavity such that said lower surface of said heat sink flange and said second surface of each of said terminal pads are in coplanar alignment, and at least a portion of said first surface of said each of said terminal pads overlies said upper surface of said heat sink flange; interconnects electrically connecting said semiconductor die with said first surface of said terminal pads; and an encapsulant substantially encasing said frame structure, said heat sink flange, said semiconductor die, and said interconnects with at least said lower surface of said heat sink flange and said second surface of said each of said terminal pads remaining exposed from said encapsulant.
