US 5648674 AAbstract
A product such as an x-ray sensor array includes, for each unit of cell circuitry, a capacitor with upper and lower electrodes. A conductive layer that includes highly conductive metal such as aluminum is patterned to include the upper electrode of the capacitor, the contact leads of a switching element, and the data lines of the array. The upper electrode has an exposed area due to an opening in an insulating layer over it. A conductive element, such as an ITO island, is formed over the insulating layer, contacting the exposed area of the upper electrode so that the conductive element is electrically connected to one of the contact leads of the switching element through the upper electrode. The conductive elements of adjacent units can be separated by the minimum spacing necessary to ensure isolation. Or each unit's conductive element can be offset slightly from the data and scan lines and can also be pulled back from the channel of the switching element, which can be a TFT.

The invention addresses complexities that arise in forming circuitry on a substrate. More specifically, the invention addresses complexities that arise in forming an array of cells on a substrate, where each cell includes a storage capacitor that has one electrode connected to a conductive element that lies over the electrode.
The product in which the invention is implemented can be a two-dimensional (2D) array, for example, with two sets of conductive lines extending in perpendicular directions. Each line extending in one direction, referred to as a data line, can provide signals to or receive signals from a column of the array; each line extending in another direction, referred to as a scan line, can provide signals to select a row of the array. The product can be an array with M scan lines and N data lines. For the mth scan line and the nth data line, the array can include (m×n)th cell circuitry near the crossing region where the nth data line crosses the mth scan line, the cell circuitry including a switching element, a capacitive element, and a conductive element as described above.
The conductive element of the (m×n)th cell circuitry can extend beyond the cell area bounded by the mth and (m+1)th scan lines and the nth and (n+1)th data lines, overlapping the mth scan line. The conductive element can be separated from the conductive element of an adjacent cell's circuitry by a spacing just sufficient for isolation. The second insulating layer can be sufficiently thick that coupling between the conductive element and the scan line does not significantly slow propagation of signals on the scan and data lines. Alternatively, the conductive element can be offset from the edges of the scan lines and data lines sufficiently to avoid introducing noise due to charge carrier injection or cross-talk.
FIG. 1 is a schematic layout diagram showing a product, with an array in which a conductive line, first and second contact leads, and a capacitive electrode are all formed in a layer that includes a highly conductive metal.
The act in box 306 then produces first insulating layer 202, conductive semiconductive layer 204, and insulating layer 206 by a sequence of PECVD steps. First insulating layer 202 can be silicon nitride deposited at about 300°-380° C. to a thickness of about 3000 Å. Semiconductive layer 204 can be a layer of intrinsic a-Si that includes 5-12% hydrogen and is deposited at about 230°300° C. to a thickness of about 300-500 Å. Insulating layer 206 can be silicon nitride deposited primarily as an etch stop at 200°-250° C. to a thickness of about 1000-1500 Å.
The act in box 312 deposits semiconductor layer 210. The act in box 312 can deposit heavily n-doped amorphous silicon 62 with 0.5-2% phosphorous and 5-15% hydrogen at 200°-250° C. to a thickness of about 1000 Å. The act in box 312 could also optionally include a preliminary etch to remove some parts of layer 210.
The act in box 322 produces a patterned layer that forms each unit's conductive element 230. The act in box 322 can deposit ITO using reactive sputter techniques in 0.5-1.5% O2 to a thickness of about 500-1000 Å. The act in box 322 can then use photolithographic techniques to mask and then etch the resulting layer to produce conductive element 230. The act in box 322 can also anneal the conductive elements at a temperature of 200°-230° C. for approximately one hour. As noted above, the mask used in box 322 can preserve spacings of 10 μm between adjacent conductive elements, or any spacing of 3-10 μm that is just sufficient to ensure isolation between adjacent conductive elements.
The structure described above has been successfully implemented in an 1536×1280 x-ray sensor array with a pitch for each unit of cell circuitry between 100-150 μm and with a spacing of approximately 10 μm between conductive elements of adjacent cells.
The implementation described above includes 1536×1280 units of cell circuitry with a pitch for each unit between 100-150 μm, but other array sizes and pitches could be used. For example, the implementation could be used with materials like selenium to produce arrays ranging from 8"×10" high resolution arrays with 50-60 μm units to 14"×18" arrays with 60-100 μm units.
