Abstract:
A pressure assembled semiconductor package comprising:a first die having a metallized top surface and a metallized bottom surface;a second die having a metallized bottom surface;a first conductive lead, a bottom of the first conductive lead being in direct contact with the top metallized surface of first die and adapted to provide an electrical connection to the first die;at least a second conductive lead in direct contact with the bottom metallized surface of first die and adapted to provide another electrical connection to the first die; anda spring element adapted to bias the first die and second die against their respective leads;a third conductive lead, a top of the third conductive lead being in direct contact with the metallized bottom surface of the second die and adapted to provide an electrical connection to the second die;an electrically insulating material located on top of the first conductive lead and on a bottom of the third conductive lead, the insulating material adapted to electrically isolate the first and third conductive leads; anda heat sink having walls that create a cavity such that the pressure assembled semiconductor package can be readily pressed into the cavity and that the walls of the cavity provide a stop against which the insulation material is pressed by the springing element.
