Scanning probe microscopy system for mapping nanostructures on a surface of a sample and metrology frame therefore
A scanning probe microscopy system for mapping nanostructures on a surface of a sample, comprises a metrology frame, a sensor head including a probe tip, and an actuator for scanning the probe tip relative to the sample surface. The system comprises a clamp for clamping of the sample, which clamp is fixed to the metrology frame and arranged underneath the sensor head. The clamp is arranged for locally clamping of the sample in a clamping area underneath the probe tip, the clamping area being smaller than a size of the sample such as to clamp only a portion of the sample. Moreover, a metrology frame for use in scanning probe microscopy system as described includes a clamp for clamping of a sample, wherein the clamp is fixed to the metrology frame such as to be arranged underneath the sensor head.
Electrostatic Force Detector With Improved Shielding And Method Of Using An Electrostatic Force Detector
An electrostatic force detector (EFD) for measuring electrostatic force of a surface under test (SUT) includes a force detector comprising a cantilevered arm and a probe. The EFD has a shield with a hole through which the probe extends and is positioned to prevent electromagnetic energy from the SUT from reaching the cantilevered arm and most of the probe, and preventing light from reaching the SUT. A method for selecting a voltage range for an EFD measuring a charge on an SUT includes measuring with the EFD two voltages at or near the end-points of an estimated voltage-range, and then comparing the polarities. If the polarities differ, the estimated voltage-range is selected. However, if the polarities are the same, then the estimated voltage range is adjusted to provide a new estimated voltage-range, which is then tested for purposes of determining whether the charge on the SUT is within the range.
Structure for achieving dimensional stability during temperature changes
A heated or cooled sample holding stage for use in a nanoindentation measurement system is described. The geometry of the design and the selection of materials minimizes movement of a sample holder with respect to a nanoindentation tip over a wide range of temperatures. The system controls and minimizes motion of the sample holder due to the heating or cooling of the tip holder and/or the sample holder in a high temperature nanoindentation system. This is achieved by a combination of geometry, material selection and multiple sources and sinks of heat. The system is designed to control both the steady state and the transient displacement response.
