Publication number: 20230236512Abstract: Methods for training a process model and determining ranking of simulated patterns (e.g., corresponding to hot spots). A method involves obtaining a training data set including: (i) a simulated pattern associated with a mask pattern to be printed on a substrate, (ii) inspection data of a printed pattern imaged on the substrate using the mask pattern, and (iii) measured values of a parameter of the patterning process applied during imaging of the mask pattern on the substrate; and training a machine learning model for the patterning process based on the training data set to predict a difference in a characteristic of the simulated pattern and the printed pattern. The trained machine learning model can be used for determining a ranking of hot spots. In another method a model is trained based on measurement data to predict ranking of the hot spots.Type: ApplicationFiled: March 7, 2023Publication date: July 27, 2023Applicant: ASML NETHERLANDS B.V.Inventors: Youping ZHANG, Maxime Philippe Frederic Genin, Cong Wu, Jing Su, Weixuan Hu, Yi Zou

Patent number: 10304322Abstract: An apparatus comprising a wireless communication device for enabling the remote control of a medical apparatus The apparatus includes a remote control enable device comprising a transmitter and one or more switches, actuatable by enable buttons. The buttons allow an operator to close the switch(es), causing the transmitter to send a status signal related to the status (open or closed) of the switch(es), to a receiver configured to communicate said status signal to a control unit. The control unit verifies the signal on a number of criteria. When all required criteria have been met, remote control of the medical apparatus is allowed. In an embodiment the remote control enable device is configured to maintain the power supply to a transmitting chip sufficiently long, upon opening a switch, so that a check can be performed on the correct functioning of the switch after the switch has been opened.Type: GrantFiled: January 27, 2016Date of Patent: May 28, 2019Assignee: Ion Beam Applications S.A.Inventors: Vincent Bossier, David Wikler, Frédéric Genin, Sofie Gillis, Christophe Bauvir, Henri Bourmorck, Geoffroy Herbin, Olivier Scalbert
