    Abstract: Methods and systems for determining a configuration for an optical element positioned in a collection aperture during wafer inspection are provided. One system includes a detector configured to detect light from a wafer that passes through an optical element, which includes a set of collection apertures, when the optical element has different configurations thereby generating different images for the different configurations. The system also includes a computer subsystem configured for constructing additional image(s) from two or more of the different images, and the two or more different images used to generate any one of the additional image(s) do not include only different images generated for single collection apertures in the set. The computer subsystem is further configured for selecting one of the different or additional configurations for the optical element based on the different images and the additional image(s).

    Abstract: The present invention is thus directed to an automated system of varying the optical path length in a sample that a light from a spectrophotometer must travel through. Such arrangements allow a user to easily vary the optical path length while also providing the user with an easy way to clean and prepare a transmission cell for optical interrogation. Such path length control can be automatically controlled by a programmable control system to quickly collect and stores data from different path lengths as needed for different spectrographic analysis. Moreover, the system utilizes configured wedge shaped windows to best minimize the reflections of light which cause periodic variation in transmission at different wave lengths (commonly described as “channel spectra”). Such a system, as presented herein, is able to return best-match spectra with far fewer computational steps and greater speed than if all possible combinations of reference spectra are considered.

    Abstract: An approach for IR-based metrology for detecting stress and/or defects around TSVs of semiconductor devices is provided. Specifically, in a typical embodiment, a beam of IR light will be emitted from an IR light source through the material around the TSV. Once the beam of IR light has passed through the material around the TSV, the beam will be analyzed using one or more algorithms to determine information about TSV stress and/or defects such as imbedded cracking, etc. In one embodiment, the beam of IR light may be split into a first portion and a second portion. The first portion will be passed through the material around the TSV while the second portion is routed around the TSV. After the first portion has passed through the material around the TSV, the two portions may then be recombined, and the resulting beam may be analyzed as indicated above.

    Abstract: A liquid sample is dropped onto the upper surface of a transparent and cylindrical light-transmitting body (22), and the liquid sample is maintained as a droplet by the surface tension. From above the liquid sample, a transparent cover plate (25) is lowered down to the position where the lower surface thereof touches a spacer (23) in order that the liquid sample is held in the small gap formed between the upper surface of the light-transmitting body (22) and the lower surface of the transparent cover plate (25). A measurement light is provided into the liquid sample held in this manner from immediately above it, and passes through the liquid sample. The transmitted light emitted downwards through the light-transmitting body (22) is introduced into a spectro-detecting unit to be spectro-measured. The measurement optical path length can be adjusted by the height of the spacer (23). This enables an easy transmission spectro-measurement of an extremely small amount of liquid sample.

    Abstract: An optical absorption gas analyser for determining the concentration of a target gas in a sample is disclosed. The analyser comprises a chamber for containing the sample in use; a radiation source assembly arranged to emit radiation into the chamber; a first radiation detector assembly arranged to detect radiation transmitted along a first optical path through the chamber and a second radiation detector assembly arranged to detect radiation transmitted along a second optical path through the chamber, wherein the length of the second optical path which the sample can intercept is shorter than that of the first optical path. The analyser further comprises a processor adapted to generate a sensing signal SS based on the detected radiation transmitted along the first optical path and a reference signal SR based on the detected radiation transmitted along the second optical path. The processor determines the concentration of the target gas in the sample based on a comparison of the sensing signal with the reference signal.

    Abstract: A method and device for measuring a concentration of a preselected gas in a gas sample are disclosed. The device comprises a Herriott type multipass cell (10) having a center axle (74) and a housing (80A, 80B) surrounding and spaced from the axle to provide a tubular sample cavity (84). The gas sample is pumped through the sample cavity via apertures (154, 156) provided in opposed ends of the axle. A first mirror (44) and a second mirror (46) are supported at opposed ends of the axle. A light source, e.g. a laser or LED, is provided for emitting a light beam into the sample cavity via an entry aperture (30) in the first mirror, the light beam having a wave length at which the preselected gas strongly absorbs. The beam is reflected between the mirrors for a number of times before exiting the cell via an exit aperture (48) in the second mirror and impinging on a detector (52). The device further comprises a reference detector (32) for monitoring the intensity of the unattenuated light beam and a detector for detecting the intensity of light transmitted through the second mirror after a single pass through the cell. The light source is operatively connected to a heat control assembly having a heat sink and the gas sample is passed said heat sink to augment temperature control of the light source.
