A casual opportunity immediately following the Millennium Café to learn about the breadth of analytical capabilities within the Materials Characterization Laboratory (MCL). These brief (30 minute) multi-technique and interdisciplinary talks will highlight applications (not theory) to provide useful insights to novice and experienced researchers working across various science and engineering challenges.
After Café: Strategies for Better Cross-Sectional Imaging
March 26, 2024
Cross-sectional SEM imaging is commonly used in nanofabrication for coating thickness measurement, process verification, and failure analysis. Cleaving is frequently the method of choice for generating a cross-sectional sample for analysis. However, this approach may inadvertently damage the sample which then poses challenges for accurate imaging. By using a focused ion beam (FIB) instrument it is possible to create highly site specific cross sections with minimal artifacts for almost any structure/device/material. In this talk I will highlight several applications for the efficient use of FIB ross-sectional imaging to accurately characterize a range of devices and layered material systems. - Bangzhi Liu
