摘要： Light of an observation wavelength range is irradiated upon a sample object to measure spectral reflection ratios, and an waveform is developed from the spectral reflection ratios. Based on the total number of peaks and valleys found in the interference waveform and two wavelengths specified within the observation wavelength range, possible ranges for the film thicknesses of the respective transparent films are determined. While changing tentative film thicknesses of the respective transparent films each by a predetermined film thickness pitch within the film thickness ranges, a deviation between theoretical spectral reflectance and measured spectral reflectance with respect to the tentative film thicknesses is calculated to thereby find a film thickness combination which causes the deviation to be minimum.

摘要： A semiconductor wafer (WF) is supported on a movable table mechanism (50). A light (L1) is applied to the surface of the semiconductor wafer to inspect the surface state of the semiconductor wafer. In order to maintain the surface of the wafer at the focal point of an objective lens (11) and maintaining the angle of the wafer in perpendicular to the optical axis of the objective lens, a light beam (B1) is generated and directed to the wafer. The reflected light (B2) is divided into first and second beams (BD1, BD2). The first light beam is received by a one-dimensional PSD (position sensing device), while the second light beam is received by a two-dimensional PSD. In response to respective outputs of the one-dimensional PSD and the two-dimensional PSD, the movable table mechanism is driven so as to maintain an in-focus state of the wafer and the objective lens even when the wafer is moved for scanning of respective regions on the wafer.

摘要： A method of measuring light reflected by a test sample with a microscopic photometric system. The test sample placed in an in-focus position of an objective is irradiated, and light reflected by the test sample is measured. Stray light generated by microscopic optics including the objective is measured with the test sample placed in an out-of-focus position of the objective. Light actually reflected by the test sample is determined from a difference between the reflected light and the stray light measured.

摘要： In a spectroscopic ellipsometer, light emitted from a light source enters a measurement surface of a substrate through an optical system in a lighting part so as to incline to the measurement surface to be directed to a light receiving device, and ellipsometry is performed based on spectral intensity of reflected light reflected on the measurement surface, the spectral intensity being acquired by the light receiving device. In focusing of the spectroscopic ellipsometer, a focus position of the measurement surface is obtained based on a total light amount in a predetermined wavelength band of the reflected light, the total light amount being obtained by the light receiving device. In the spectroscopic ellipsometer, since the optical system for ellipsometry and the optical system for focusing are common, it is possible to eliminate influences of change of the optical systems by temperature change or the like and to achieve high accurate focusing.

摘要： In a trench shape measuring apparatus, a substrate having a trench pattern extending in a predetermined trench direction on a measurement area is held by a holding part. A light emission part applies illumination light to the measurement area and reflected light of the illumination light from the measurement area is spectrally dispersed by a diffraction grating of a spectroscope, to acquire a measured spectral reflectance. Since the diffraction grating is arranged so that an angle formed between a direction on the substrate corresponding to a grating direction of the diffraction grating and the trench direction becomes 45 degrees, even if an oscillation direction of the reflected light from the substrate is limited by influence of the trench pattern, it is possible to accurately obtain a spectral reflectance of the measurement area without influence of polarization of the reflected light and obtain a depth of the trench pattern with accuracy.

摘要： A maximum value of a spectral reflectance at each wavelength with changes in the thickness of a top layer of a multi-layer dielectric film is determined as a maximum reflectance represented by a curve (MLmax) in a graph. In the presence of a residual metal film on the multi-layer dielectric film, the spectral reflectance changes from a curve (A50) to a curve (A5) in the graph with the decrease in the thickness of the residual metal film. In the absence of the residual metal film, the spectral reflectance is represented by a curve (A0) in the graph. Based on the foregoing, a peak wavelength at which the spectral reflectance of a multi-layer film to be judged reaches a peak is determined in a specified wavelength range. When the reflectance of the multi-layer film to be inspected at the peak wavelength is greater than the maximum reflectance, it is concluded that the multi-layer film to be inspected has the residual metal film. When the reflectance of the multi-layer film to be inspected at the peak wavelength is equal to or less than the maximum reflectance, it is concluded that the residual metal film is absent. The presence or absence of the residual metal film on the multi-layer dielectric film is inspected using simple calculation without the need for optical constants of metal.

摘要翻译： 将多层电介质膜的顶层的厚度变化的各波长处的光谱反射率的最大值确定为由曲线图中的曲线（MLmax）表示的最大反射率。 在多层电介质膜上存在残留金属膜的情况下，随着残留金属膜厚度的减小，光谱反射率从图中的曲线（A50）变化到曲线（A5）。 在不存在残留金属膜的情况下，光谱反射率由曲线（A0）表示。 基于上述，在规定的波长范围内确定待判断的多层膜的光谱反射率达到峰值的峰值波长。 当在峰值波长处检查的多层膜的反射率大于最大反射率时，得出结论，待检查的多层膜具有残留的金属膜。 当在峰值波长下检查的多层膜的反射率等于或小于最大反射率时，得出残留金属膜不存在的结论。 使用简单的计算来检查多层电介质膜上残留金属膜的存在或不存在，而不需要金属的光学常数。

摘要： With three-dimensional detecting method and a three-dimensional detecting apparatus, it is possible to accurately detect a surface shape of a sample. While moving a sample, confocal images Fj (where j=1, 2, . . . , n) are taken at a plurality of heights which are different from each other in the direction of height. Based on the confocal images Fj, surface height data H(x, y) with which the quantity of light becomes maximum in the height direction are calculated on each pixel (x, y), and further, a maximum light quantity I(x, y) with the surface height data H(x, y) are calculated. For each pixel, the surface height data H(x, y) of a pixel under noise processing (x, y) are corrected based on surface height data H(a, b) and a maximum light quantity I(a, b) at peripheral pixels which surround the pixel under noise processing (x, y).
