In recent years a major improvement was achieved allowing the acquisition of the time-resolved temperature responses of weak thermal spots that enhances defect localization in 3D stacked semiconductor architectures. The assessment of a defect's depth based on the numerical estimation of the delay between excitation and thermal response by analyzing the value of the lock-in phase is often prone to thermal noise and parasitic effects. In sample structures that contain partial or full transparence for the infrared signal between the origin and the sample surface, the interference of the direct (radiated) and the conducted signal component largely falsifies the phase value on which the classical depth estimation relies. In the present study blind source separation based on independent component analysis of the thermal signals was successfully applied to separate interfering signal components arising from direct thermal radiation and conduction for a precise estimation of the defect depth.","PeriodicalId":188323,"journal":{"name":"ISTFA 2021: Conference Proceedings from the 47th International Symposium for Testing and Failure Analysis","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130682038","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}

Focused Ion Beam (FIB) is one of the most powerful techniques for precise location sampling in nanometer-scale for Transmission Electron Microscope (TEM) sample preparation. As semiconductor technology improves continuously, 3D NAND is requiring higher stacks to increasing the capacity of storage. In general, an operator counts the cell layer manually to reach the desire layer on TEM sample before thinning. It is not easy way to make TEM samples at the exact desired layer. To make it easier, automatic cell layer counting workflow is introduced in this paper. This progress is carried out until the desired target cell is reached. Furthermore, marking is performed on the target cell layer. This automation recipe is able to offer simple process to count the desired cell layer without manual action and make TEM sample preparation easily.","PeriodicalId":188323,"journal":{"name":"ISTFA 2021: Conference Proceedings from the 47th International Symposium for Testing and Failure Analysis","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114668237","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 synergy, the ps-laser is used to quickly remove large volumes of bulk material while the SEM/Xe Plasma FIB is used for precise end-pointing to the feature of interest and fine surface polishing after laser. The concept of having a stand-alone laser tool obeys the logic of maximizing productivity as both systems can work simultaneously and continuously. As application examples we first present a full workflow to prepare an artefact-free, delamination-free cross-section in an AMOLED mobile display. We also present applications examples that require cm-sized long cuts to cut through whole microelectronic devices, or removal of cubic-mm of material to prepare mm-sized cross-sections in packages. We discuss a way how to implement correlation data across the laser and FIBSEM platforms through SYNOPSYS Avalon SW allowing precise navigation to the area of interest using layout circuit overlays.
