Publication number: 20140314898Abstract: A heat-reactive resist material contains copper oxide, and silicon or silicon oxide, and is formed so that the content of silicon or silicon oxide in the heat-reactive resist material is 4.0 mol % or more less than 10.0 mol % in terms of mole of silicon. A heat-reactive resist layer is formed using the heat-reactive resist material, is exposed, and then, is developed with a developing solution. Using the obtained heat-reactive resist layer as a mask, dry etching is performed on a substrate with a fluorocarbon to manufacture a mold having a concavo-convex shape on the substrate surface. At this point, it is possible to control a fine pattern comprised of the concavo-convex shape.Type: ApplicationFiled: November 16, 2012Publication date: October 23, 2014Inventors: Yoshimichi Mitamura, Takuto Nakata

Publication number: 20140295331Abstract: A nanoporous film patterned by direct photolithography and a method for preparing the same are provided. Since a precursor of the material is the mixture of a nano template material and a photoresist and the mixture still has the basic physical properties of the photoresist, a film is formed on a substrate by a standard photolithography process and a micro-sized patterned structure is realized. The mixture with the patterned structure is chemically etched to remove the template material to form a porous polymer film, or the mixture with the patterned structure is carbonized at a high temperature and then the template material is removed to form a porous carbon film. The nanoporous film patterned by direct photolithography and the method for preparing the same have the advantages of simple operation, low cost and good integration with other micro electric mechanical systems.Type: ApplicationFiled: April 27, 2013Publication date: October 2, 2014Applicant: Tsinghua UniversityInventors: Xiaohong Wang, Caiwei Shen

Patent number: 8846301Abstract: An orthogonal process for photolithographic patterning organic structures is disclosed. The disclosed process utilizes fluorinated solvents or supercritical CO2 as the solvent so that the performance of the organic conductors and semiconductors would not be adversely affected by other aggressive solvent. One disclosed method may also utilize a fluorinated photoresist together with the HFE solvent, but other fluorinated solvents can be used. In one embodiment, the fluorinated photoresist is a resorcinarene, but various fluorinated polymer photoresists and fluorinated molecular glass photoresists can be used as well. For example, a copolymer perfluorodecyl methacrylate (FDMA) and 2-nitrobenzyl methacrylate (NBMA) is a suitable orthogonal fluorinated photoresist for use with fluorinated solvents and supercritical carbon dioxide in a photolithography process.Type: GrantFiled: May 21, 2009Date of Patent: September 30, 2014Assignee: Cornell UniversityInventors: Christopher K.

Patent number: 8828493Abstract: Methods are disclosed for forming a layered structure comprising a self-assembled material. An initial patterned photoresist layer is treated photochemically, thermally, and/or chemically to form a treated patterned photoresist layer comprising a non-crosslinked treated photoresist. The treated photoresist is insoluble in an organic solvent suitable for casting a material capable of self-assembly. A solution comprising the material capable of self-assembly dissolved in the organic solvent is casted on the treated layer, and the organic solvent is removed. The casted material is allowed to self-assemble with optional heating and/or annealing, thereby forming the layered structure comprising the self-assembled material. The treated photoresist can be removed using an aqueous base and/or a second organic solvent.Type: GrantFiled: December 18, 2009Date of Patent: September 9, 2014Assignee: International Business Machines CorporationInventors: Joy Cheng, William D.
