    • A defect inspection method and device for irradiating a linear region on a surface-patterned sample mounted on a planarly movable table, with illumination light from an inclined direction relative to a direction of a line normal to the sample, next detecting in each of a plurality of directions an image of the light scattered from the sample irradiated with the illumination light, then processing signals obtained by the detection of the images of the scattered light, and thereby detecting a defect present on the sample; wherein the step of detecting the scattered light image in the plural directions is performed through elliptical lenses in which elevation angles of the optical axes thereof are different from each other, within one plane perpendicular to a plane formed by the normal to the surface of the table on which to mount the sample and the longitudinal direction of the linear region irradiated with the irradiation light, the elliptical lenses being formed of circular lenses having left and right portions thereof cut.
    • 一种用于照射安装在平面可移动台上的表面图案样品上的线性区域的缺陷检查方法和装置,其具有相对于垂直于样品的线的方向的倾斜方向的照明光,接下来在多个 指示从照射光照射的样品散射的光的图像,然后处理通过检测散射光的图像而获得的信号,从而检测样品上存在的缺陷; 其特征在于,所述检测多个方向的散射光图像的步骤是通过椭圆形透镜进行的,所述椭圆透镜在光学轴的仰角彼此不同的垂直于与所述表的表面法线形成的平面的一个平面内 在其上安装样品和用照射光照射的线性区域的纵向方向,椭圆形透镜由其左侧和右侧部分切割的圆形透镜形成。
