Patent ID: 7923737

Claim:
A combined semiconductor device comprising: a substrate comprised of crystalline silicon, the substrate including a first surface; a dielectric film bonded to the first surface of the substrate; a three-terminal switch array having a plurality of three-terminal light-emitting switching elements formed from a thin semiconductor film comprised of a compound semiconductor, the three-terminal light-emitting switching elements being arranged in an array from a first three-terminal light-emitting switching element to an N-th three-terminal light-emitting switching element on the first surface of the substrate, N being an integer greater than unity, each three-terminal light-emitting switching element having a first electrode, a second electrode, and a control electrode, and wherein the thin semiconductor film is bonded to the dielectric film such that the dielectric film is between the substrate and the three-terminal switch array; a shift register circuit with first to N-th output terminals for output of logic signals, N being an integer greater than unity; wherein the shift register circuit is formed in the substrate; a driving controller outputting driving current in synchronization with output of the logic signals from the shift register circuit; a ground electrode; a layer of control electrode wiring formed from a thin film, the control electrode wiring conducting the logic signal from the N-th output of the shift register circuit to the control electrode of the N-th three-terminal light-emitting switching element, for each integer N from one to N, and extending along the first surface of the substrate and a surface of the thin semiconductor film; a layer of power-supply wiring formed from a thin film, the power-supply wiring connecting the first electrode of each three-terminal light-emitting switching element to the driving controller, and extending along the first surface of the substrate and the surface of the thin semiconductor film; and a layer of ground wiring formed from a thin film, the ground wiring connecting the second electrode of each three-terminal light-emitting switching element to the ground electrode, and extending along the first surface of the substrate and the surface of the thin semiconductor film.
