Abstract:
An apparatus for testing an integrated circuit structure having a first and second face and a plurality of devices thereon, each device having a first and second terminal, the first terminals of a group of said devices being connected together by a common contact formed on the first face, each device in the group having its second terminal on the second face, the structure being supported on a sheet of flexible material on a supporting surface with the first face of the structure in contact with the sheet, said apparatus comprising:a pedestal interposed between the sheet and the supporting surface so as to protrude above the supporting surface, said pedestal being shorter in a first dimension than the structure, to provide an unsupported portion of the sheet where the structure extends beyond said pedestal;a first probe in contact with the first face above the unsupported portion of the sheet;a second probe in contact with a second terminal of one device in the group, a test signal being applied between the first and second probes; anda sensor constructed and positioned to detect whether said one device operates properly in response to the test signal.
