简介:
Next-generation nano- and quantum devices have increasingly complex 3D structure. As the dimensions of these devices shrink to the nanoscale, their performance is often governed by interface quality or precise chemical or dopant composition. Here, we present the first phase-sensitive extreme ultraviolet imaging reflectometer. It combines the excellent phase stability of coherent high-harmonic sources, the unique chemical sensitivity of extreme ultraviolet reflectometry, and state-of-the-art ptychography imaging algorithms.

报告人介绍:
Steve Shu is an Associate Professor at the School of Electrical and Computer Engineering in The University of Sydney. He received his B. Eng degree from Shanghai Jiaotong University in 2002, M.Eng from Nanyang Technological University in 2004, and Ph.D from The University of Melbourne in 2007, all in electrical and electronic engineering. Before returning to academia, he had worked more than a decade in the microelectronics industry (e.g., microelectronics research institute IMEC, the world's leading semiconductor equipment supplier ASML in Netherlands).
