Publication number: 20250385101Abstract: Embodiments described herein relate to a method that includes forming a patterning stack over a substrate, wherein the patterning stack includes an underlayer over the substrate that includes an extreme ultraviolet (EUV) sensitive material with —OH terminated chains, and a resist layer over the underlayer. The method further includes exposing regions of the patterning stack with EUV electromagnetic radiation, and increasing a temperature of the patterning stack, wherein OH and/or H2O is released from exposed regions of the underlayer and diffuses into the resist layer. The method may also include developing the resist layer.Type: ApplicationFiled: May 21, 2025Publication date: December 18, 2025Inventors: NANCY FUNG, CHI-I LANG, MICHAEL STOLFI, HIDEYUKI KANZAWA, LEQUN LIU

Patent number: 12363948Abstract: Horizontal gate-all-around devices and methods of manufacturing same are described. The hGAA devices comprise an oxide layer and a semiconductor material layer between source regions and drain regions of the device. The method includes growing a conformal epitaxial layer on a nanosheet channel layer, followed by radical plasma oxidation (RPO) to oxidize the conformal epitaxial layer. An alternative method includes growing a conformal epitaxial layer on a nanosheet channel layer, followed by a surface treatment, and then radical plasma oxidation (RPO) to oxidize the conformal epitaxial layer.Type: GrantFiled: October 11, 2021Date of Patent: July 15, 2025Assignee: Applied Materials, Inc.Inventors: Myungsun Kim, Andy Lo, Eric Davey, Michael Stolfi, Benjamin Colombeau
