Abstract: Resistivity probes can be used to test integrated circuits. In one example, a resistivity probe has a substrate with multiple vias and multiple metal pins. Each of the metal pins is disposed in one of the vias. The metal pins extend out of the substrate. Interconnects provide an electrical connection to the metal pins. In another example, a resistivity probe has a substrate with a top surface and multiple elements extending from the substrate. Each of the elements curves from the substrate to a tip of the element such that each of the elements is non-parallel to the top surface of the substrate.

Abstract: A continuous variable spacing probe pin device, including first and second probe pins. The first and second probe pins are configured to measure a property of a conductive layer. In a first configuration, the first and second probe pins include respective first portions arranged to contact the conductive layer to measure the property. In a second configuration, the first and second probe pins include respective second portions arranged to contact the conductive layer to measure the property. A first area for each respective first portion is different from a second area for each respective second portion.

Abstract: Metal film thickness can be determined using the sheet resistance, resistivity, and temperature coefficient of resistivity for the metal film. Variation in film thickness measurements caused by resistivity can be reduced or eliminated. A probe head may be used for some of the measurements of the metal film. The probe head can include a temperature sensor used during sheet resistance measurements. A wafer on a chuck is heated, such as using the chuck or the probe head, for the measurements.

Abstract: Multiple pin probes and methods for controlling such multiple pin probes to support parallel measurements are disclosed. The method may include: establishing electrical contact between a multiple pin probe and a subject of measurement; selecting two pins out of a plurality of pins included in the multiple pin probe as current-carrying pins; selecting more than two additional pins out of the plurality of pins included in the multiple pin probe as voltage-metering pins; injecting a current through the current-carrying pins; simultaneously measuring voltage signals through the voltage-metering pins; calculating a simulated voltage distribution curve at least partially based on the voltage signals simultaneously measured through the voltage-metering pins; and determining one or more processor monitor parameters of the subject of measurement at least partially based on the simulated voltage distribution curve.
