    • PROBLEM TO BE SOLVED: To provide a technology enabling an SEM device to accelerate inspection speed.SOLUTION: Device manufacturing method using the inspection apparatus with charged particle beam comprises the steps of: moving a stage so that a lower left corner of a first search die in a lower part of a wafer is positioned nearly at a center of a camera, and obtaining a pattern matching template image; when a second search die is in a right adjacent side of the first search die, and a third search die is in an upper adjacent side of the second search die, moving the stage and conducting automatic pattern matching using the template image so that exact coordinate values of patterns for the second search die and the third search die are obtained; calculating moving amount of motion to an upper adjacent die with reference to a relationship between the second search die pattern matching coordinate and the third search die pattern matching coordinate and moving the stage to a coordinate where a pattern of an upper adjacent die to the first search die is expected to exist; and conducting the pattern matching using the template image so that an exact coordinate value of a searching pattern is repeatedly updated and obtained. Consequently, accuracy is improved.
    • 要解决的问题:提供使SEM装置能够加快检测速度的技术。 < P>解决方案:使用带有带电粒子束的检查装置的装置制造方法包括以下步骤:移动台,使得晶片下部的第一搜索管芯的左下角几乎位于晶片的中心 相机,并获得模式匹配模板图像; 当第二搜索模具位于第一搜索模具的右侧,并且第三搜索模具位于第二搜索模具的上部相邻侧时,移动平台并使用模板图像进行自动模式匹配,使得精确坐标 获得第二搜索模具和第三搜索模具的图案的值; 参考第二搜索模具匹配坐标和第三搜索模具匹配坐标之间的关系,将移动的运动量计算到上部相邻模具,并将平台移动到上部相邻模具的图案到第一次搜索的坐标 死亡预计会存在; 并使用模板图像进行图案匹配,使得重复地更新并获得搜索图案的精确坐标值。 因此,精度提高。 版权所有(C)2012,JPO&INPIT
