As the temperature increases during the TEM sample preparation, it may lead to deformation and shrinkage in PR profiles. In this study, we analyze the impact when performing the sample preparation at a cold temperature using a cryo-FIB to minimize deformation and shrinkage issues. To test this methodology, the TEM sample preparation process was performed under different conditions. From these experiments, the TEM results with full cryo conditions showed that the PR line to space ratio was closest to the target, which is the sample’s real line to space ratio (1:1), and the bottom anti-reflective coating (BARC) shrinkage was minimized.","PeriodicalId":20443,"journal":{"name":"Proceedings","volume":"100 3","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-11-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136352359","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The author explains how the consistency was achieved by adopting important changes such as (1) application of the 1-volt electrochemical bias, (2) optimization of etching solution agitation at 3.5 RPM, and (3) adoption of a symmetrical stainless-steel cathode. With the power of consistency, the added benefit of the adoption changes is the correct measurement of wire bond integrity tests such as wire pull, wire diameter, and magnitude of etch. The paper also discusses additional improvements to address the issue of long cycle time via laser ablation.","PeriodicalId":20443,"journal":{"name":"Proceedings","volume":"101 4","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-11-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136352539","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this work, the process of preparation of ultrathin planar-to-cross-section conversion transmission electron microscopy (TEM) samples using a gallium dual-column focused ion beam (FIB)/scanning electron microscope (SEM) system is examined. Sample preparation technique in this paper is aimed at repeatably isolating features in the 5-30 nm range, while limiting common issues such as amorphization, lamella warpage, and the curtain effect (or “curtaining”). This can be achieved through careful selection of FIB parameters including ion beam energy, ion beam current, stage tilt, and deposited protective layer materials and thicknesses, which are all discussed in this work.","PeriodicalId":20443,"journal":{"name":"Proceedings","volume":"98 15","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-11-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136353338","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

While optical probing has been used extensively for semi-invasive/non-invasive attacks, its resolution limits and obsolescence in advanced technologies have necessitated exploring other techniques. Electron-beam probing (EBP) has emerged as a powerful method, offering 20x better spatial resolution than optical probing, and applies to sub- 7nm flip-chips and advanced 3D architecture systems. However, the increased resolution of EBP also poses a threat to sensitive information on these advanced chips, calling for developing countermeasures to secure assets. By understanding the capability of EBP, the potential of using EBP to extract sensitive data such as encryption keys, soft IP, neural network parameters, and proprietary algorithms will be discussed. This paper delves into the principles behind EBP, its capabilities, challenges for this technique, and potential applications in failure analysis and potential attacks. It highlights the need for developing effective countermeasures to protect sensitive information on advanced node technologies.","PeriodicalId":20443,"journal":{"name":"Proceedings","volume":"98 4","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-11-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136353349","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
