Methods and systems for analyte detection and analysis
Provided are systems and methods for analyte detection and analysis. A system can comprise an open substrate configured to rotate. The open substrate can comprise an array of immobilized analytes. A solution comprising a plurality of probes may be directed, via centrifugal force, across the array during rotation of the substrate, to couple at least one of the plurality of probes with at least one of the analytes to form a bound probe. A detector can be configured to detect a signal from the bound probe via continuous rotational area scanning of the substrate.
METHOD OF IMAGING A SURFACE USING A SCANNING PROBE MICROSCOPE
A method includes scanning a probe laterally across a surface so that the probe follows a scanning motion across the surface and steering a detection beam onto the probe via a steering mirror, the detection beam reflecting from the probe in the form of a return beam. The method also includes moving the steering mirror so that the detection beam follows a tracking motion which is synchronous with the scanning motion and the detection beam remains steered onto the probe by the steering mirror and using the return beam to obtain image measurements, each indicative of a measured height of a respective point on the surface. An associated height error measurement is obtained for each point on the surface, each measurement being indicative of a respective error in the measured height. The height error measurements are used to correct the image measurements so as to generate corrected image measurements.
SYSTEMS AND APPROACHES FOR SEMICONDUCTOR METROLOGY AND SURFACE ANALYSIS USING SECONDARY ION MASS SPECTROMETRY
Systems and approaches for semiconductor metrology and surface analysis using Secondary Ion Mass Spectrometry (SIMS) are disclosed. In an example, a secondary ion mass spectrometry (SIMS) system includes a sample stage. A primary ion beam is directed to the sample stage. An extraction lens is directed at the sample stage. The extraction lens is configured to provide a low extraction field for secondary ions emitted from a sample on the sample stage. A magnetic sector spectrograph is coupled to the extraction lens along an optical path of the SIMS system. The magnetic sector spectrograph includes an electrostatic analyzer (ESA) coupled to a magnetic sector analyzer (MSA).

Thermally stable, drift resistant probe for a scanning probe microscope and method of manufacture
A probe assembly for a surface analysis instrument such as an atomic force microscope (AFM) that accommodates potential thermal drift effects includes a substrate defining a base of the probe assembly, a cantilever extending from the base and having a distal end, and a reflective pad disposed at or near the distal end. The reflective pad has a lateral dimension (e.g., length) between about twenty-five (25) microns, and can be less than a micron. Ideally, the reflective pad is patterned on the cantilever using photolithography. A corresponding method of manufacture of the thermally stable, drift resistant probe is also provided.
