Patent number: 11143961Abstract: The present invention relates to resist compostions, in particular to photoresists that can be used in photolithography, especially in the fabrication of integrated circuits and derivative products. The resist compositions of the invention include an anti-scattering component which has a significant amount of empty space, and thus fewer scattering centers, such that radiation-scattering events are more limited during exposure. Such anti-scattering effects can lead to improved resolutions by reducing the usual proximity effects associated with lithographic techniques, allowing the production of smaller, higher resolution microchips. Furthermore, certain embodiments involve anti-scattering components which are directly linked to the resist components, which can improve the overall lithographic chemistry to provide benefits both in terms of resolution and resist sensitivity.Type: GrantFiled: September 29, 2016Date of Patent: October 12, 2021Assignee: The University of ManchesterInventors: Scott Lewis, Richard Winpenny, Stephen Yeates, Antonio Fernandez

Patent number: 6579657Abstract: A resist pattern, containing a material capable of generating an acid by exposure to light, is covered with a resist containing a material capable of crosslinkage in the presence of an acid. The acid is generated in the resist pattern by application of heat or by exposure to light, and a crosslinked layer is formed at the interface as a cover layer for the resist pattern, thereby causing the resist pattern to be thickened. Thus, the hole diameter of the resist pattern can be reduced, or the isolation width of a resist pattern can be reduced.Type: GrantFiled: March 27, 1998Date of Patent: June 17, 2003Assignee: Mitsubishi Denki Kabushiki KaishaInventors: Takeo Ishibashi, Toshiyuki Toyoshima, Keiichi Katayama, Ayumi Minamide
