A two-terminal circuit has top cells (3) and bottom cells (5) bonded to an insulating substrate (12) with the top cells (3) bonded on top of the bottom cells (5). The bottom cells (5) are wired together in series through ribbon bonds (A). The top cells (3) are in parallel with each other generating a voltage that is equivalent to one larger top cell. The top cells (3) are connected to the circuit through ribbon bonds (B, C, D). The ribbon bonds are connected to the topsides of the top and bottom cells. The substrate (12) contains metal die bonding pads for the base contacts to the bottom cells. Bases are connected to emitters of adjacent bottom cells in series connections. |
