Patent number: 8821978Abstract: A method of forming a layered structure comprising a domain pattern of a self-assembled material utilizes a negative-tone patterned photoresist layer comprising non-crosslinked developed photoresist. The developed photoresist is not soluble in an organic casting solvent for a material capable of self-assembly. The developed photoresist is soluble in an aqueous alkaline developer and/or a second organic solvent. A solution comprising the material capable of self-assembly and the organic casting solvent is casted on the patterned photoresist layer. Upon removal of the organic casting solvent, the material self-assembles, thereby forming the layered structure.Type: GrantFiled: December 18, 2009Date of Patent: September 2, 2014Assignee: International Business Machines CorporationInventors: Joy Cheng, William D. Hinsberg, Ho-Cheol Kim, Young-Hye Na, Daniel Paul Sanders, Linda Karin Sundberg, Hoa D. Truong, Gregory Michael Wallraff, Atsuko Ito

Patent number: 8822139Abstract: A method for providing an ordered polymer layer at a surface of a substrate includes depositing a self-assemblable polymer layer directly onto a primer layer on a substrate to provide an interface between the self-assemblable polymer layer and the primer layer, and treating the self-assemblable polymer layer to provide self-assembly into an ordered polymer layer, such as a block copolymer, having first and second domain types at the interface. The primer layer is adapted to improve its chemical affinity to each domain type at the interface, in response to the presence of the respective domain type in the self-assembled polymer at the interface during the self-assembly of the self-assemblable polymer layer into the ordered polymer layer. This may lead to reduction in defect levels and/or improved persistence length for the ordered polymer layer. The method may be useful for forming resist layers for use in device lithography.Type: GrantFiled: January 19, 2011Date of Patent: September 2, 2014Assignee: ASML Netherlands B.V.Inventors: Emiel Peeters, Sander Frederik Wuister, Roelof Koole

Patent number: 8822140Abstract: A resist pattern-forming method includes applying a radiation-sensitive resin composition on a substrate to form a resist film. The radiation-sensitive resin composition includes an acid-labile group-containing polymer and a photoacid generator. The resist film is exposed. The resist film is developed using a developer including an organic solvent in an amount of no less than 80% by mass to a total amount of the developer. The radiation-sensitive resin composition has a contrast value ? of from 5.0 to 30.0. The contrast value ? is calculated from a resist dissolution contrast curve obtained by changing only a dose of a light used for exposing the resist film.Type: GrantFiled: August 8, 2013Date of Patent: September 2, 2014Assignee: JSR CorporationInventors: Hirokazu Sakakibara, Hiromu Miyata, Koji Ito, Taiichi Furukawa

Publication number: 20140242522Abstract: In the field of photolithography and, notably, photolithography in the extreme ultraviolet, a photolithography method is provided in which a first mask blank is produced that can have defects, an individual mapping of the positions of the defects of this mask blank is established using an inspection machine, and, for each defect, an exclusion zone is defined around the defect. Then, two complementary masks are produced, one with the first mask blank and with the desired design pattern, except in the exclusion zones, the latter being black, the other with a second mask blank and with the desired design pattern parts in the exclusion zones, all the rest of the second mask being black. The exposure of the surface to be processed by photolithography is done in two successive steps using the two complementary masks.Type: ApplicationFiled: February 25, 2014Publication date: August 28, 2014Inventors: Cyril VANNUFFEL, Jean-Louis IMBERT
