Abstract:
1. A semiconductor composite apparatus, comprising: a first substrate having first and second elongated outer regions and an elongated intermediate region between said first and second outer regions; a semiconductor thin film layer disposed above said second outer region of said first substrate and comprising a first semiconductor material; light emitting elements formed in said semiconductor thin film layer; first driving circuits disposed above said first outer region of said first substrate, said first driving circuits comprising logic circuits that are fabricated on polycrystalline silicon material, that receive input signals from external circuitry, and that generate drive signals based on the input signals, said first driving circuits having a predetermined thickness; connection pads disposed above said first outer region of said first substrate, adjacent said first driving circuits; wiring conductors connecting said connection pads to said first drive circuits, said wiring conductors having a thickness that is smaller than the thickness of said first driving circuits; second driving circuits disposed above said intermediate region of said first substrate, said second driving circuits comprising single crystal silicon material; drive signal wiring means for connecting said first driving circuits to said second driving circuits to convey said drive signals to said second driving circuits; and drive power wiring means for connecting said second driving circuits to said light emitting elements to supply drive power to said light emitting elements.
