Patent number: 12437993Abstract: New lithographic compositions for use as EUV adhesion layers are provided. The present invention provides methods of fabricating microelectronics structures using those compositions as well as structures formed by those methods. The method involves utilizing an adhesion layer immediately below the photoresist layer. The adhesion layer can either be directly applied to the substrate, or it can be applied to any intermediate layer(s) that may be applied to the substrate, such as an alpha-carbon, spin-on carbon, spin-on silicon hardmask, metal hardmask, or deposited silicon layer. The preferred adhesion layers are formed from spin-coatable, polymeric compositions. The inventive method improves adhesion and reduces or eliminates pattern collapse issues.Type: GrantFiled: March 18, 2024Date of Patent: October 7, 2025Assignee: Brewer Science, Inc.Inventors: Andrea M. Chacko, Vandana Krishnamurthy, Yichen Liang, Hao Lee, Stephen Grannemann, Douglas J. Guerrero
