That includes the whole spectrum of techniques: chemical, physical, electrical, magnetic, optical, in-situ, and real-time control and monitoring. As such, there is likely to be a topic of interest to almost anyone engaged in the metrology and analysis of semiconductor products and manufacturing, and beyond.<\/p>\n\n\n\n<p><br>After the plenary session starting the conference, the breadth of the conference can be seen in the session titles \u2013 AI, Machine Learning, and Hybrid Metrology; and Microscopy (<strong>Tuesday<\/strong>), Magnetics\/Spintronics; Metrology for Patterning; 7-10 nm Metrology and Defect Inspection; Nanoscale and Interfacial Compositional Characterization and Metrology (<strong>Wednesday<\/strong>), Metrology for Advanced Packaging; Emerging Characterization and Metrology; \u201cGeneral\u201d; TCAD; and Metrology for Silicon Photonics and Sensors (<strong>Thursday<\/strong>). Over the three days, there are 34 presentations, and unlike some conferences, no parallel sessions. <\/p>\n\n\n\n<p><br>On the Tuesday and Wednesday evenings there are formal poster sessions, but they are also available for viewing in the coffee and lunch breaks through to the Thursday lunchtime; with 46 papers to view, there\u2019s good opportunity to talk with the authors. <\/p>\n\n\n\n<p><br>Socially, there is the opening reception at 6.30 on Monday 1st April, the conference banquet on Tuesday evening, and drinks and snacks will be served at the evening poster sessions.<\/p>\n\n\n\n<p><br><strong>Tuesday<\/strong><br>After the conference opening, by long-term conference chair David Seiler, we have three keynote talks:<\/p>\n\n\n\n<ul class=\"wp-block-list\"><li><em>Beyond CMOS Computing<\/em>, from Ian Young of Intel<\/li><li><em>Frontiers in Memory Technology and Metrology Drivers<\/em>, by Gurtej Sandhu of Micron<\/li><li><em>Impact of Quantum Information Science on the Future of Nanoelectronics<\/em>, by Carl Williams, NIST<br><\/li><\/ul>\n\n\n\n<p>In the first session, <strong>AI, Machine Learning, and Hybrid Metrology<\/strong>, which is spread over lunch, we have three papers on deep learning\/machine learning\/AI, from imec, Oakridge Labs, and Nova Instruments.<br><\/p>\n\n\n\n<ul class=\"wp-block-list\"><li><em>Machine Learning and Deep Learning Opportunities for Metrology and Process Control<\/em>, Phillip Leray, Imec<\/li><li><em>Deep Learning in Atomically Resolved Imaging: from Learning Physics to Atom by Atom Fabrication<\/em>, Sergei Kalinin, Oakridge<\/li><li><em>AI and Machine Learning for Advanced Semiconductor Metrology and Process Control<\/em>, Shay Wolfling, Nova <\/li><\/ul>\n\n\n\n<p>Then we get into the <strong>Microscopy<\/strong> session, with a variety of techniques:<\/p>\n\n\n\n<ul class=\"wp-block-list\"><li><em>What Does Near-line TEM Bring to the Table for the CMOS Manufacturing Industry?<\/em> Paul van der Heide, imec<\/li><li><em>When Ion or Electron Channeling meets Crystal Orientation Mapping<\/em>, Anne Delobbe, Tescan Orsay<\/li><li><em>Low Energy Electron Resist Exposures<\/em>, Rudolf Tromp, IBM<\/li><li><em>Accurate and Precise Analysis of Nanoscale Semiconductor Devices with Atom-probe Tomography: a Physicist\u2019s Dream or an Analyst\u2019s Nightmare?<\/em> Wilfried Vandervorst, imec <\/li><\/ul>\n\n\n\n<p>The last paper of the session is a must-see for me, since looking at the current generation of 7-nm going down to 5-nm devices, we are literally counting atoms when we try and analyse them, and the atom probe is the last resort for trying to do chemical analysis of the doping of these parts. I suspect the answer is closer to the nightmare, since there are so many opportunities for contamination and error; but I have known Wilfried for years, and he is an engaging speaker with likely some tantalising information for us. <\/p>\n\n\n\n<p>After the last paper we have posters (I will detail them after going through the spoken presentations), hors d\u2019oeuvres and drinks, followed by the banquet.<br><\/p>\n\n\n\n<p><strong>Wednesday<\/strong><\/p>\n\n\n\n<p>First up, we start with <strong>Magnetics\/Spintronics<\/strong>; MRAM was one of the significant topics at last year\u2019s IEDM conference, so it will be interesting to see the characterization techniques required:<\/p>\n\n\n\n<ul class=\"wp-block-list\"><li><em>Metrology for the Manufacturing Needs of MRAM<\/em>, Daniel Worledge, IBM<\/li><li><em>Metrology for Topological Spintronics Materials and Devices<\/em>, M.
