电子束检测,至关重要
半导体行业观察· 2025-05-10 02:53
如果您希望可以时常见面,欢迎标星收藏哦~ 来源:本文来自 semiengineering ,谢谢。 吞吐量仍然是一个问题,解决方案需要多种技术的结合。 事实证明,电子束检测对于发现 5 纳米以下尺寸的关键缺陷至关重要。现在的挑战是如何加快这 一流程,使其在经济上符合晶圆厂的接受度。 电子束检测因灵敏度和吞吐量之间的权衡而臭名昭著,这使得在这些先进节点上利用电子束进行 全面缺陷覆盖尤为困难。例如,对于英特尔的18A逻辑节点(约1.8纳米级)和三星数百层的3D NAND存储器,缺陷检测已达到极限。 传统检测方法在 5 纳米以下开始遭遇根本性的物理限制。光学检测系统历来是缺陷检测的主力, 但由于衍射极限、复杂材料堆叠导致的对比度降低以及日益细微的缺陷特征,在先进节点上表现 不佳。 电子束检测提供纳米级分辨率,能够捕捉光学工具可能遗漏的微小致命缺陷,但这些优势也伴随 着显著的代价。吞吐量是主要瓶颈。用单束电子束扫描整个300毫米晶圆可能需要数小时甚至数 天,远远超出了现代晶圆厂严格的时间预算。 PDF Solutions先进解决方案副总裁 Michael Yu 表示:"如果想在 7nm 或 5nm 等先进节点的生 产 ...

答:反射光波导在高分辨率、清晰度、色彩均匀性、漏光、光效利用率等指标上具 有非常明显的优势,这是底层的物理学原理决定的,但是其量产性也是全球难题。 反射光波导的显示效果优秀,公司也正在着力攻克反射光波导的量产难题,如果有 里程碑事件我们很愿意和大家交流一号工程的进展情况,欢迎保持持续关注。衍射 光波导纳米压印方案在小视场角、单色方案中,目前具有可量产性、性价比优势, 但是在全彩显示效果上还难以看到很好的方案;衍射光波导碳化硅方案,可以突破 视场角的限制,并且更加轻便,但是在大视场角的漏光、色彩均匀性等基本指标上 还未解决,并且其量产性也受制于材料端成本、供应链开发、工艺制程开发等因素。 两条技术路线各自有各自需要解决的问题,都会持续发展优化,我们认为两条技术 路线大概率会并行,在客户不同的产品定位、不同的应用场景中,各有落地。 5、问:请问反射光波导方案对光机是否有要求? 浙江水晶光电科技股份有限公司投资者关系活动记录表 编号:2025013 | | 特定对象调研 分析师会议 | | --- | --- | | 投资者关系活动 类别 | 媒体采访 业绩说明会 | | | 新闻发布会 路演活动 | ...
