EUV Lithography: Results of Single Particle Volume Charging Processes in EUV Exposure Environment With Focus On Afterglow Effects


A new technical paper titled "Particle charging during pulsed EUV exposures with afterglow effect" was published by researchers at ASML, ISTEQ B.V., and Eindhoven University of Technology. Abstract "The nanoparticle charging processes along with background spatial-temporal plasma profile have been investigated with 3DPIC simulation in a pulsed EUV exposure environment. It is found that the ... » read more

Nova METRION Use Cases


Several use cases that we will explore for the Nova METRION® system include contamination control, process excursion prevention, reactor matching, and uniformity control. The objectives of these use cases are to detect contaminants which can kill devices, improve barrier layer and source/drain function, maintain deposition uniformity that impacts downstream processes, and ensure wafer-to-wafer... » read more
