Abstract:
A chuck for testing an integrated circuit includes an upper conductive layer having a lower surface and an upper surface suitable to support a device under test. An upper insulating layer has an upper surface at least in partial face-to-face contact with the lower surface of the upper conductive layer, and a lower surface. A middle conductive layer has an upper surface at least in partial face-to-face contact with the lower surface of the upper insulating layer, and a lower surface.
