金融界2025年6月28日消息，国家知识产权局信息显示，ASML荷兰有限公司申请一项名为“具有低串扰的多带电粒子射束设备”的专利，公开号CN120221358A，申请日期为2020年05月。
专利摘要显示，本公开涉及一种具有低串扰的多带电粒子射束设备。公开了通过减少多射束设备中的二次带电粒子检测器的检测元件之间的串扰，来增强成像分辨率的系统和方法。多射束设备包括用于将来自样品的多个二次带电粒子射束投射到带电粒子检测器(140)上的电光系统。该电光系统包括第一预限制孔径板(155P)和射束限制孔径阵列(155)，第一预限制孔径板(155P)包括被配置为阻挡多个二次带电粒子射束的外围带电粒子的第一孔径；射束限制孔径阵列(155)包括被配置为修整多个二次带电粒子射束的第二孔径。带电粒子检测器可以包括多个检测元件(140_1、140_2、140_3)，其中多个检测元件中的一个检测元件与多个二次带电粒子射束中的对应修整后的射束相关联。
