  • Patent number: 9275978
    Abstract: A layer of microscopic, 3-terminal transistors is printed over a first conductor layer so that bottom electrodes of the transistors electrically contact the first conductor layer. A first dielectric layer overlies the first conductor layer, and a second conductor layer over the first dielectric layer contacts intermediate electrodes on the transistors between the bottom electrodes and top electrodes. A second dielectric layer overlies the second conductor layer, and a third conductor layer over the second dielectric layer contacts the top electrodes. The devices are thus electrically connected in parallel by a combination of the first conductor layer, the second conductor layer, and the third conductor layer. Separate groups of the devices may be interconnected to form more complex circuits. The resulting circuit may be a very thin flex-circuit.
