Frank Ogletree of Lawrence Berkeley National Labs.\u00a0 As our industry barrels towards implementing UEV lithography in manufacturing, we still lack answers to very fundamental questions about the exposure mechanisms for EUV resists.\u00a0 Ogletree described one way to study the complicated interactions of a high-energy photon with a resist material by interacting those photons with model compounds in the gas phase.\u00a0 Simplifying the interactions allows for much more detailed measurements and easier interpretation of results.\u00a0 The surprising outcome was how high-energy EUV photons could cause massive fragmentation of the resist molecules.\u00a0 The full implications for resist chemistry are still unknown.<\/p>\n<p>Dr. Nishikawa of the University of Tokyo gave an interesting talk on directly exposing and cutting DSA (directed self-assembly) patterns using direct-write e-beam lithography.\u00a0 The results looked very promising.\u00a0 My favorite student paper was by Yao Luo of Texas A&amp;M, who is working on my favorite topic \u2013 stochastic-induced line-edge roughness.\u00a0 In a technique that I have also successfully employed, she used a Monte Carlo simulator to create simulated scanning electron micrographs of simulated rough features with known statistical characteristics.\u00a0 She then examined the impact on SEM noise on the ability to properly measure feature roughness.\u00a0 Great work.<\/p>\n<p>The multi-beam maskwriter company IMS gave an update on their tool development.\u00a0 They are currently shipping a maskwriter tool with 262,144 programmable electron beams, each with 20-nm resolution capability.\u00a0 This enables the printing of a state-of-the-art photomask in about 10 hours, limited mostly by the data path (275 TB of data for one mask).\u00a0 This is great progress for mask making, but we all want to know, how much faster can this tool become?<\/p>\n<p>There were several interesting papers on DSA (from MIT and NIST, among others), but little progress on its application to the semiconductor industry.\u00a0 Carolien Boeckx of Imec discussed the healing properties of DSA for contact holes.\u00a0 Unfortunately, you still can\u2019t heal a missing contact.<\/p>\n<p>I gave the last paper of the last day of the conference.\u00a0 My thanks to the 25 hearty souls who persevered to the end and sat through my talk on how SEM errors influence line-edge roughness measurements.\u00a0 I then made a mad rush to the airport to catch the last plane to Austin.\u00a0 I needn\u2019t have rushed.\u00a0 Thanks to weather my flight was canceled and I found myself captive in Orlando for one more night.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>61st International Conference on Electron, Ion, and Photon Beam Technology and Nanofabrication Orlando, FL, May 30 \u2013 June 2, 2017 Unlike some conferences, the 3-beams conference moves to a new location each year.\u00a0 This means that some years it is in a location I like better than other years. \u00a0Last year was Pittsburg (liked it), [&hellip;]<\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[2],"tags":[],"class_list":["post-535","post","type-post","status-publish","format-standard","hentry","category-microlithography"],"_links":{"self":[{"href":"https:\/\/lithoguru.com\/life\/index.php?rest_route=\/wp\/v2\/posts\/535","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/lithoguru.com\/life\/index.php?rest_route=\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/lithoguru.com\/life\/index.php?rest_route=\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/lithoguru.com\/life\/index.php?rest_route=\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/lithoguru.com\/life\/index.php?rest_route=%2Fwp%2Fv2%2Fcomments&post=535"}],"version-history":[{"count":1,"href":"https:\/\/lithoguru.com\/life\/index.php?rest_route=\/wp\/v2\/posts\/535\/revisions"}],"predecessor-version":[{"id":536,"href":"https:\/\/lithoguru.com\/life\/index.php?rest_route=\/wp\/v2\/posts\/535\/revisions\/536"}],"wp:attachment":[{"href":"https:\/\/lithoguru.com\/life\/index.php?rest_route=%2Fwp%2Fv2%2Fmedia&parent=535"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/lithoguru.com\/life\/index.php?rest_route=%2Fwp%2Fv2%2Fcategories&post=535"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/lithoguru.com\/life\/index.php?rest_route=%2Fwp%2Fv2%2Ftags&post=535"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
