ABSTRACT:
A repair structure for an array with first and second sets of lines that cross includes a repair line extending within the array, approximately parallel to at least one line in the first set and crossing a subset of the lines in the second set. The repair line is separated from the lines it crosses by an insulating layer but a repair operation can form an electrical connection between the repair line and an open line it crosses by operating on the region where they cross. For example, the insulating layer can be melted so that molten metal from the lines mixes to form an electrical connection. The repair structure also includes a connecting lead outside the array through which the repair line can be electrically connected to the signal circuitry for the open line, so that the open line receives signals from or provides signals to its signal circuitry as though it were continuous. The connecting lead can be connected to the signal circuitry through a highly conductive line on a printed circuit board or through a highly conductive line on the substrate but peripheral to the array. The repair line can cross all the lines in the second set. Or the repair structure can also include a second repair line collinear with the first. A split array with scan lines and data lines can therefore include two repair structures with a total of four repair lines, allowing four repairs to be made.
