Claim Text:
1. A solid-state transducer (SST) device comprising: a conductive carrier substrate; a first terminal; a second terminal, wherein the first and second terminals are positioned to couple to a power supply having an output voltage, and wherein at least a portion of the conductive carrier substrate defines the second terminal; a plurality of SST dies electrically connected in series between the first and second terminals, wherein the plurality of SST dies includes a first SST die adjacent to a second SST die, wherein individual SST dies have a forward junction voltage less than the output voltage, and wherein the individual SST dies comprise— an interconnect region between the first and second SST dies, wherein a portion of the second contact of first SST die extends beyond the backside of the first contact and beyond the transducer structure of the first SST die into the interconnect region, and wherein the portion of the second contact of the first SST die electrically couples to the first contact of the adjacent second SST die such that the first and second SST dies are electrically coupled together in series at the interconnect region, wherein the transducer structure of the first SST die and the transducer structure of the second SST die define an opening at the interconnect region that exposes the portion of the second contact that extends beyond the backside of the of the first contact of the first SST die and a portion of the first contact of the second SST die that extends beyond the backside of the second SST die such that the second contact of the first SST die is coupled to the first contact of the second SST die in the opening.
