摘要:
본발명은짧은시간에정밀도좋게웨이퍼의가공면의연마불량을검사하는것을목적으로한다. 웨이퍼검사방법은, 웨이퍼(W)의가공면을촬상하는공정과, 촬상데이터의소정의픽셀중, 주변픽셀보다화소값이높은픽셀을특징점으로서추출하여제1 화상을작성하는공정과, 촬상데이터의소정의픽셀중, 주변픽셀보다화소값이낮은픽셀을특징점으로서추출하여제2 화상을작성하는공정을가지며, 제1, 제2 화상으로부터웨이퍼의가공면을검사한다.

本发明的目的是在短时间内精确地检查晶片的经处理表面的抛光故障。 晶片检查方法包括:对晶片的经处理表面进行成像的工艺; 通过从成像数据的每个预定区域中的像素中提取具有比周边像素高的像素值作为特征点的像素来形成第一图像的处理; 以及通过从成像数据的每个预定区域中的像素中提取具有比周边像素的像素值低的像素作为特征点的像素来形成第二图像的处理。 第一和第二图像用于检查晶片的经处理的面。
摘要(英):
An object of the present invention is to accurately in a short time to check the polishing defects in the machined surface of the wafer.
Wafer inspection method comprising the steps of creating a first image by extracting a predetermined pixel value is higher than one pixel, the surrounding pixels of pixels of the step of imaging data for imaging the processed surface of the wafer (W) as the feature points, the captured image data the predetermined has a step of creating a second image by extracting a, a feature point is a pixel value is lower than the surrounding pixels, pixels of the pixel, the first and determines the processing surface of the wafer from the second image.
