Patent ID: 7586080

Claim:
A layered structure comprising: a carrier-transporting substructure that includes one or more solution processing artifacts and that, in operation in an application, transports charge carriers in a thickness direction anisotropically, with negligible transport in directions perpendicular to the thickness direction; the carrier-transporting substructure having a facing surface extending approximately perpendicularly to the thickness direction; and a circuitry substructure with surface parts disposed toward the facing surface of the carrier-transporting substructure; the surface parts including: one or more charge-flow surface parts through which charge carriers flow to or from the carrier-transporting substructure's facing surface during operation in the application, each charge-flow surface part being on a respective electrically conductive region of the circuitry substructure; and one or more channel surface parts, each on a respective semiconductive channel region of the circuitry substructure; in operation in the application, each of a set of the channel regions operating as an acceptable switch.
