| description | A measuring apparatus for measuring a semiconductor wafer, or a film or coating thereon, includes an electrically conductive wafer chuck and a probe having a probe body defining an internal cavity in fluid communication with an electrically conductive and elastic or resilient membrane. The membrane and a topside of the semiconductor wafer are moved into spaced relation when the semiconductor wafer is supported by the wafer chuck. A pressure of fluid supplied to the internal cavity of the probe body is selectively controlled whereupon the membrane expands into contact with the topside of the semiconductor wafer. A suitable test stimulus is applied to the membrane and the semiconductor wafer and the response of the semiconductor wafer to the test stimulus is measured. |
