摘要： A capillary tube used to transfer a liquid sample into a detection cell following separation by a chromatographic system is modified by plugging or otherwise severely restricting its flow. Near its plugged end, said tube is drilled to provide a plurality of holes or ports perpendicular thereto and penetrating into the central flowing core of said tube so as to direct outflow from the tube perpendicularly therefrom. The outer diameter of this so-modified capillary tube is selected to be of a size comparable to, though smaller than, the detection cell diameter into which it transfers the flowing sample. In this manner, fluid transferred into a detection cell by said modified capillary tube will be split into a plurality of smaller streams flowing outwardly therefrom and striking the adjacent detector cell walls almost immediately. Because of the close proximity of the emerging split streams to the walls of the detection cell, the eddies produced thereby will be very small and the contents of the detection cell will be homogenized rapidly.

摘要： A method and apparatus is disclosed for measuring the refractive index difference between a reference and sample liquid based on an interferometric design. The resultant device has an almost unlimited range of operation in contrast to a conventional interferometric refractometer of the so-called polarization type whose dynamic range is restricted to a relatively narrow range of refractive indices. The measurement of the refractive index difference between a sample and reference cell is achieved by measuring the angle through which the plane of polarization of a combined beam has rotated. For the conventional device, this angle is restricted to about .pi. radians which corresponds to a half wavelength shift between the reference and sample components of said combined beam. The extended range device disclosed permits this angle to be tracked and measured accurately over many rotations. The rotation tracking is achieved by one of three embodiments, the preferred of which involves the use of a liquid crystal retarder. The other two techniques incorporate, respectively, a rotating polarizer and a doubly split beam. All three embodiments permit the measurement of both the sine and cosine of the rotation angle and, thereby, allows a four quadrant arctangent calculation to yield the rotation angle directly. The error associated with such measurements is not a function of the rotation angle of the combined beams.

摘要： A corona-microwave system can generate accurate capacitance-voltage (C-V) and resistance-voltage (R-V) curves, thereby allowing the accurate determination of gate film capacitance, sheet resistance of implanted regions, and mobility of a substrate under a gate. The corona-microwave system can combine a corona deposition system, a Kelvin probe, and a microwave probe. The corona deposition system can deposit a corona charge on a surface of the semiconductor. The Kelvin and microwave probes can be used to make first and second electrical measurements of a layer/region of the semiconductor. The steps of charge deposition and probe measurements can be repeated to generate a curve plotting the first and second electrical measurements. Because the first and second electrical measurements can be accurately made, the extracted information from the curve is also accurate.

摘要： A system for characterizing material properties in miniature semiconductor structures performs a scatterometry analysis on inelastically scattered light. The system can include a narrowband probe beam generator and a detector. A single wavelength probe beam from the narrowband probe beam generator produces scattered light from a measurement pattern on a test sample. The scattered light is measured by the detector, and the measurement data (e.g., Raman spectrum) is used in a scatterometry analysis to determine material properties for the measurement pattern. The detector can measure either incoherent inelastically scattered light (e.g., using a spectrometer) or coherent inelastically scattered light (e.g., using an array detector). If the measurement pattern dimensions are substantially similar to actual device dimensions, the material property distributions determined for the measurement pattern can be applied to the actual devices on the test sample.

摘要： An x-ray metrology system includes an e-beam generator to cause a test sample to emit x-rays, x-ray optics for focusing the x-rays, and an x-ray imager to generate an image of the test sample from the focused x-rays. Because the x-ray imager provides a direct representation of the x-ray emission characteristics of the test sample, the resolution of a measurement taken using such a sensor is limited only by the resolution of the sensor (and any focusing optics), rather than by the amount of e-beam spread in the thin film. The x-ray imaging can be performed for object planes at the test sample that are not parallel to the test sample, thereby allowing vertical dimension data to be accurately generated by the x-ray imaging system.

摘要： A spectroscopic ellipsometry system directs a near infra-red (NIR) probe beam at a test sample to allow metrology to be performed on vertical structures within the test sample. Because silicon is relatively transparent to NIR light, structural information can be determined from the polarization effects produced by the test sample, in a manner similar to that used with IR spectroscopic ellipsometry systems. However, unlike IR light, which requires delicate and costly optical and measurement components (e.g., vibration-sensitive Fourier transform sensors), NIR light can be directed and detected using more robust and inexpensive components (e.g., array-based detectors), thereby making a NIR spectroscopic ellipsometry system much more affordable and usable than conventional IR spectroscopic ellipsometry systems.

摘要： A system for analyzing a thin film uses an energy beam, such as a laser beam, to remove a portion of a contaminant layer formed on the thin film surface. This cleaning operation removes only enough of the contaminant layer to allow analysis of the underlying thin film, thereby enhancing analysis throughput while minimizing the chances of recontamination and/or damage to the thin film. An energy beam source can be readily incorporated into a conventional thin film analysis tool, thereby minimizing total analysis system footprint. Throughput can be maximized by focusing the probe beam (or probe structure) for the analysis operation at the same location as the energy beam so that repositioning is not required after the cleaning operation. Alternatively, the probe beam (structure) and the energy beam can be directed at different locations to reduce the chances of contamination of the analysis optics.

摘要： A system for analyzing a thin film simultaneously applies a pulsed cleaning beam and a measurement beam to an analysis location on a test sample to enhance measurement accuracy. The pulsed cleaning beam prevents contaminant regrowth on the analysis location during the actual measurement. To minimize the effects of thermal transients from the pulsed cleaning beam on measurement data, cleaning pulses can be timed to fall between data samples. Alternatively, data sampling can be blocked during each cleaning operation (i.e., each cleaning pulse and subsequent cooldown period) or data levels can be clamped at measurement levels from just before the start of the cleaning operation for the duration of the cleaning operation. Alternatively, data samples taken during each cleaning operation can be discarded or replaced with data samples from just before the cleaning operation using post-processing techniques.
