Abstract:
An electronic component array includes a backplane substrate, and a plurality of integrated circuit elements on the backplane substrate. Each of the integrated circuit elements includes a chiplet substrate having a connection pad and a conductor element on a surface thereof. The connection pad and the conductor element are electrically separated by an insulating layer that exposes at least a portion of the connection pad. At least one of the integrated circuit elements is misaligned on the backplane substrate relative to a desired position thereon. A plurality of conductive wires are provided on the backplane substrate including the integrated circuit elements thereon, and the connection pad of each of the integrated circuit elements is electrically connected to a respective one of the conductive wires notwithstanding the misalignment of the at least one of the integrated circuit elements. Related fabrication methods are also discussed.
