Abstract: Current Voltage and Capacitance Voltage (IV and CV) measurements are critical in measurement of properties of electronic materials especially semiconductors. A semiconductor testing device to accomplish IV and CV measurement supports a semiconductor wafer and provides a probe for contacting a surface on the wafer under control of an atomic Force Microscope or similar probing device for positioning the probe to a desired measurement point on the wafer surface. Detection of contact by the probe on the surface is accomplished and test voltage is supplied to the semiconductor wafer. A first circuit for measuring capacitance sensed by the probe based on the test voltage and a complimentary circuit for measuring Fowler Nordheim current sensed by the probe based on the test voltage are employed with the probe allowing the calculation of characteristics of the semiconductor wafer based on the measured capacitance and Fowler Nordheim current.

Abstract: A semiconductor wafer processing tool has a support structure for a coarse motion positioning system. A measurement head having a rigid super structure is supported from the support structure by vibration isolators and a top plate is mounted to the super structure. A vacuum transfer chuck is releasably carried by the coarse motion positioning system and releasably adherable to the top plate by application of vacuum. The vacuum transfer chuck supports a semiconductor wafer.

Abstract: A diode is formed at the tip of a pointed portion of a probe of a scanning probe microscope. When the diode is forward biased, the current through the diode varies with the temperature of the diode. The magnitude of the current is an indication of the temperature of the tip of the probe. If the tip is scanned over a surface, a thermal map of the surface can be made and hot spots on the surface located. In some embodiments, the pointed portion of the probe is made of a semiconductor material (for example, silicon). A layer of a metal (for example, platinum) is made to contact the semiconductor material of the pointed portion only at the tip of the pointed portion, thereby forming a very small temperature sensing Schottky diode at the tip of the pointed portion.

Abstract: An accurate method of measuring the two-dimensional doping profile of a semiconductor by measuring an electrical parameter along a path of a dopant iso-concentration. Thin vertical or horizontal slices of the semiconductor integrated circuit are provided and are probed to allow the electrical parameter to be measured through a single concentration area.
