Patent

CA 2178390

An imager array data line repair structure for use in high performance imager arrays includes a first and a second plurality of address lines that are disposed in respective layers with an intermediate layer having at least one insulative material disposed therebetween. The imager device further includes at least one integral address line repair segment that is disposed in the same layer as the first address lines and that is electrically isolated from the first address lines; the integral address line repair segment is disposed so as to underlie a repair portion of the second address line, with the intermediate layer disposed therebetween, and has a width substantially the same as the overlying second address line. In initial fabrication, the integral address line repair segment is electrically isolated from the overlying repair segment of the second address line; in the event a repair has been effected, the repair portion of the second address line is electrically coupled to the underlying integral address line repair segment through laser welds.
