Abstract: Apparatus for electrical and optical nanoprobing at resolution beyond optical diffraction limit. Navigation microscope is configured for navigation to a region of interest. A probe spatial positioner supports a fork and an oscillating piezotube is attached to the free end of the fork and provides an output indicating of a distance to the sample. A single-mode optical fiber having a near-field transducer formed at an end thereof is attached to the oscillating piezotube such that the near-field transducer extends below the oscillating piezotube towards the sample. A photodetector is positioned to detect photons collected from the sample. The near-field transducer may be formed as a tapered section formed at the end of the single-mode optical fiber, a metallic coating formed at a tip of the tapered section, and an aperture formed in the metallic coating so as to expose the tip of the tapered section through the metallic coating.

Abstract: A method for testing an integrated circuit (IC) using a nanoprobe, by using a scanning electron microscope (SEM) to register the nanoprobe to an identified feature on the IC; navigating the nanoprobe to a region of interest; scanning the nanoprobe over the surface of the IC while reading data from the nanoprobe; when the data from the nanoprobe indicates that the nanoprobe traverse a feature of interest, decelerating the scanning speed of the nanoprobe and performing testing of the IC. The scanning can be done at a prescribed nanoprobe tip force, and during the step of decelerating the scanning speed, the method further includes increasing the nanoprobe tip force.

Abstract: A charged particle beam, such as an electron beam or an ion beam, scans a device while a signal is applied to the device. As the particle beam scans, it locally heats the device, altering the local electrical characteristics of the device. The change in electrical characteristic is detected to and correlated to the position of the electron beam to localize a defect.

Abstract: A system for analyzing a sample is described. The system for analyzing a sample includes a probe and a controller circuit. The controller circuit configured to control a movement of the probe to at least a first position and a second position on the sample based on navigation data. In response to the movement of the probe, the controller circuit is configured to adjust a force of the probe on the sample at the first position from a first force value to a second force value and the force of the probe on the sample from a third force value to a fourth force value at said second position on the sample. And, the controller circuit is configured to acquire sample data with the probe at the first position on the sample.
