ABSTRACT:
Disclosed is a method of testing ultra large area integrated circuits. The circuit has a plurality of individually addressable elements. The method comprises providing a dispersed chargeable powder with the integrated circuit in proximity to and above the powder. At least one device of the integrated circuit is electrically selected. An electrical potential is applied between the integrated circuit and the dispersed powder. The potential causes the chargeable particles to adhere to substantially only functional selected devices of the integrated circuit, thereby differentiating between functional and non-functional devices.
