    • A pattern defect inspection apparatus capable of detecting minute defects on a sample with high sensitivity without generating speckle noise in signals is realized. Substantially the same region on a surface of a wafer is detected by using two detectors at mutually different timings. Output signals from the two detectors are summed and averaged to eliminate noise. Since a large number of rays of illumination light are not simultaneously irradiated to the same region on the wafer, a pattern defect inspection apparatus capable of suppressing noise resulting from interference of a large number of rays, eliminating noise owing to other causes and detecting with high sensitivity minute defects on the sample without the occurrence of speckle noise in the signal can be accomplished.
    • 实现能够以高灵敏度检测样品上的微小缺陷而不产生信号中的斑点噪声的图案缺陷检查装置。 通过在相互不同的定时使用两个检测器来检测晶片表面上的基本上相同的区域。 来自两个检测器的输出信号被相加和平均以消除噪声。 由于大量的照明光线不能同时照射到晶片上的相同区域,所以能够抑制由于大量光线的干扰而产生的噪声的图案缺陷检查装置,消除由于其它原因引起的噪声和高检测 可以实现样品上的灵敏度微小缺陷,而不会在信号中发生斑点噪声。

    • A method and apparatus for detecting defects are provided for detecting defects or foreign matter on an object to be inspected. The apparatus includes a movable stage for mounting a specimen, an illumination system for irradiating a circuit pattern with light from an inclined direction, and an image-forming optical system for forming an image of an irradiated detection area on a detector from the upward and oblique directions. With this arrangement, diffracted light and scattered light caused on the circuit pattern through the illumination by the illumination system is collected. A spatial filter is provided on a Fourier transform surface for blocking the diffracted light from a linear part of the circuit pattern. The scattered and reflected light received by the detector is converted into an electrical signal. The converted electrical signal of one chip is compared with that of the other adjacent chip.

    • The invention relates to a device production process for forming a circuit pattern on a substrate such as semiconductor device. To enable a stable inspection of a minute foreign particle and a pattern defect occurring in manufacture of a device at a high speed and with a high sensitivity, an object to be inspected on which a transparent film is formed, is irradiated with a beam which is emitted from an illuminator whose illumination direction and illumination angle are selected from a plurality of choices to be optimum, so that scattered reflected light from a minute foreign particle defect on the object or the transparent film is effectively detected by eliminating a noise from the pattern formed on the object, and a detection optical system is optimized by evaluating and adjusting, with an image forming performance checker, an image forming performance of the detection optical system included in an inspecting apparatus.
