Abstract

In an is-TPG method in which lasers having two different wavelengths are used to generate a wavelength-variable far-infrared light, a far-infrared light (TPG light) having an unstable output at a broad wavelength is also slightly generated at the same time with only one laser light. The generated is-TPG and the TPG light are converted, after passing through a specimen, to near-infrared light inside a nonlinear optical crystal for detection and are observed by a detector. The signal light output of the is-TPG light becomes unstable due to the TPG light. According to the present invention, the TPG light is removed by means of a slit and the like (filter) immediately before the specimen and is not introduced into the nonlinear optical crystal for detection. At this time, by using a change in the emission direction when the frequency of the is TPG light is changed, the filter is moved in accordance with the frequency so that only the is-TPG light passes therethrough (see FIG. 1C).

Abstract

The present invention reduces the turnaround time of an automated analyzer. During a period when cyclic measurement by a measurement unit is unnecessary, a controller washes a reaction vessel using a washing cycle having a cycle time shorter than that of an analysis cycle. A single analysis cycle and a single washing cycle both include a reaction disc stopping period and rotation period. In the washing cycle, there is no time during the stopping period when a sample dispensing mechanism, reagent dispensing mechanism, or stirring mechanism operates but there is a time when a washing mechanism operates. The washing cycle stopping period is shorter than the analysis cycle stopping period. The amount of rotation of the reaction disk in the analysis cycle rotation period is the same as the amount of rotation of the reaction disk in the washing cycle rotation period.

Abstract

The present invention makes it possible for an automated analyzer including two or more types of photometers to obtain suitable output of the measurement results of the plurality of photometers and suitable data alarm output even if there is an abnormality, or the like, at the time of measurement. This automated analyzer includes, for example, two types of photometers having different quantitative ranges and an analysis control unit for controlling analysis that includes measurement of a given sample using the two types of photometers. If two types of data alarms corresponding to abnormalities, or the like, during measurement have been added to the two types of measurement results from the two types of photometers, the analysis control unit selects measurement result and data alarm output corresponding to the combination of the two types of data alarms and outputs the same to a user as analysis results.

Abstract

In order to prevent an erroneous determination of an on-film defect, the sensitivity of the post-inspection is reduced so that a film swelling due to a minute defect would not be detected. Classification is performed to determine whether a defect is at least one of an on-film defect and a film swelling, by performing a coordinate correction on the result of a post-inspection by an actual-defect fine alignment using the result of a pre-inspection performed with two-stage thresholds, and by checking defects against each other. In addition, classification is performed to determine whether a defect is at least one of an on-film defect and a film swelling by, during the post-inspection, preparing instruction data from information of the refractive index and thickness of a film formed on a wafer and comparing the instruction data with a signal intensity ratio of a detection system.

Abstract

In film thickness/depth measurement of a wafer in processing during etching, because the detected light intensity amount fluctuates and the measurement accuracy of the film thickness/depth decreases due to fluctuations in light intensity of the light source and fluctuations in the air of the region through which the light passes, the total light intensity or average light intensity at a given frequency is calculated from the spectroscopic spectrum measured at each time during etching processing; a present-time estimated total light intensity or estimated average light intensity, estimated using the total light intensity or average light intensity measured in the past prior to the present time is calculated; a change ratio is calculated, which is the ratio of the present-time total light intensity and estimated total light intensity, or the ratio of the average light intensity and the estimated average light intensity; the light intensity at each for wavelength at the present time is corrected using the calculated change ratio; and film thickness/depth measurement is carried out using the corrected light intensity at each wavelength.
