摘要:
Array circuitry formed at the surface of a substrate includes M scan lines that cross N data lines. The array circuitry also includes cell circuitry connected to the mth scan line and the nth data line. The cell circuitry includes a component with a data lead for receiving signals from or providing signals to the nth data line. The cell circuitry also includes connecting circuitry with first and second semiconductor lines. The first semiconductor line has a channel between the nth data line and the data lead of the component. The second semiconductor line is connected to the mth scan line and crosses the first semiconductor line at the channel. Because the second semiconductor line is conductive, signals on the mth scan line control conductivity of the channel. The semiconductor lines can be polysilicon, and the scan lines can be aluminum. The component can include a capacitive element with one electrode under the (m+1)th scan line, part of which forms the other electrode of the capacitor. The channel can be under the nth data line, leaving the cell area free. The component can also include a light transmissive cell electrode in the cell area, and the array circuitry can be used in a display, with liquid crystal material positioned along the cell electrode. The display can also include peripheral circuitry outside the boundary of the array circuitry, connected to the scan lines and data lines.

Array circuitry formed at a surface of a substrate includes a first conductive layer with M scan lines, a second conductive layer with N data lines, and cell circuitry for a region in which the mth scan line and the nth data line cross. The cell circuitry includes a component with a data lead for receiving signals from or providing signals to the nth data line. A first semiconductor layer of the cell circuitry includes a first line with a channel between a connecting point to the nth data line and a connecting point to the component's data lead. A second semiconductor layer includes a second line extending from a connecting point to the mth scan line and crossing the first line at the channel. The first and second conductive layers and the cell circuitry are formed with electrical connections at the connecting points so that signals on the mth scan line control conductivity of the first line between the nth data line and the data lead. The semiconductor layers can be polysilicon. The first semiconductor layer can be formed before the second, with the first line electrically connected to the data lead by implanting a dopant. The connections to the mth scan line and the nth data line can be metal/semiconductor interfaces, with the first conductive layer deposited on the second line and with the second conductive layer deposited on the first line through an opening in an insulating layer.
摘要:
A thin film SOI CMOS device wherein the suitably doped deposited layers of an n-channel transistor and a p-channel transistor are simultaneously deposited. The source and drain elements of one transistor and the gate element of the other transistor are formed in a lower, highly doped, semiconductor layer and are separated from the corresponding gate element and source and drain elements formed in an upper, highly doped, semiconductor layer. The layer levels are separated by two intrinsic or lightly doped semiconductor layers sandwiching a dielectric layer, so that the intrinsic or lightly doped semiconductor layer lying contiguous to the source and drain elements serves as an active channel layer and the intrinsic or lightly doped semiconductor layer lying contiguous to the gate element serves to extend the gate layer.
摘要:
A method of forming large grain polycrystalline films by deep ion implantation into a composite structure, comprising a layer of amorphous semiconductor material upon an insulating substrate. Implantation is of a given ion species at an implant energy and dosage sufficient to distrupt the interface between the amorphous layer and the substrate and to retard the process of nucleation in subsequent random crystallization upon thermal annealing.
