显微镜不同观察方法下的快速半导体检测
已刻蚀的晶圆和集成电路(IC)在生产过程中的半导体检测对于识别和减少缺陷非常重要。
高质量EBSD样品制备
本文介绍了一种使用宽离子束研磨技术为“混合”晶体材料制备可靠且有效的EBSD(电子背散射衍射)样品的方法。该方法产生的横截面具有高质量表面,这对于EBSD分析至关重要。电子背散射衍射(EBSD)材料分析是通过扫描电子显微镜(SEM)进行的。制备混合材料(CPU或铝(Al)、金刚石和石墨(C)的复合材料)的横截面,使其具有适合EBSD分析的高质量表面,可能是一个挑战。
先进的细胞超微结构研究
冷冻断裂和冷冻蚀刻是研究柔性膜相关结构(如紧密连接或肠道糖萼)的有用工具。冷冻断裂和冷冻蚀刻是两种互补的方法,通过样品玻璃化来保护目标结构,然后断开冷冻标本以揭示内部结构。冷冻蚀刻是一个后续步骤,在真空下表面冰升华以揭示更多细节。在这些技术中,喷镀金属或碳使样品能够直接在冷冻扫描电子显微镜(SEM)中成像,或作为复制膜在透射电子显微镜(TEM)中成像。这对技术用于研究细胞器、膜、层和乳液,特别适用…
