Abstract:
1. A circuit module comprising: a die attach pad having a surface and a plurality of leads surrounding the surface; a nonconductive adhesive on said surface; a first electronic circuit die, having a top surface and a bottom surface with said bottom surface directly on said nonconductive adhesive, said top surface having a plurality of bonding pads, wherein the first electronic circuit die has at least one routing path of a conductive material connecting a first bonding pad to a second bonding pad, wherein said routing path is on said top surface of said first electronic circuit die; a second electronic circuit die, having a top surface and a bottom surface with said bottom surface directly on said nonconductive adhesive, said top surface having a plurality of bonding pads; a first bonding wire connecting a bonding pad of the second electronic circuit die to the first bonding pad of the first electronic circuit die; a second bonding wire connecting the second bonding pad of the first electronic circuit die to a lead, wherein said first electronic circuit die has an electronic circuit component having a first terminal in said first electronic circuit die on said bottom surface of said first electronic circuit die, wherein said second electronic circuit die has an electronic circuit component having a second terminal in said second electronic circuit die on said bottom surface of said second electronic circuit die, wherein each of said first or second electronic circuit die is made of a substantially single crystalline silicon and further comprises: a trench filled with doped polysilicon with said trench extending from said top surface to said terminal, wherein said doped polysilicon extends from said top surface to directly contact said terminal.
