Patent number: 8394577Abstract: In a chemically amplified resist composition comprising a base resin, an acid generator, and a solvent, 1,400-5,000 pbw of the solvent is present per 100 pbw of the base resin, and the solvent comprises at least 60 wt % of PGMEA and ethyl lactate, and 0.2-20 wt % of a high-boiling solvent. A resist pattern is formed by coating the resist composition on a substrate, prebaking, patternwise exposure, post-exposure baking, development, and heat treatment.Type: GrantFiled: April 8, 2010Date of Patent: March 12, 2013Assignee: Shin-Etsu Chemical Co., Ltd.Inventors: Akinobu Tanaka, Tamotsu Watanabe, Satoshi Watanabe

Patent number: 8394578Abstract: A method of forming a resist pattern, including: forming a resist film on a substrate using a resist composition containing a base component (A) which exhibits decreased solubility in an organic solvent under action of an acid and an acid-generator component (B) which generates an acid upon exposure, conducting exposure of the resist film, and patterning the resist film by a negative tone development using a developing solution containing an organic solvent, wherein the base component (A) includes a resin component (A1) containing a structural unit (a1) derived from an acrylate ester containing an acid decomposable group which exhibits increased hydrophilicity by the action of an acid and a structural unit (a0) derived from an acrylate ester containing an —SO2— containing cyclic group.Type: GrantFiled: February 16, 2011Date of Patent: March 12, 2013Assignee: Tokyo Ohka Kogyo Co., Ltd.Inventors: Tomoyuki Hirano, Takahiro Dazai, Daiju Shiono

Patent number: 8394579Abstract: Some embodiments include methods of forming patterns in which a block copolymer-containing composition is formed over a substrate, and is then patterned to form a first mask. The block copolymer of the composition is subsequently induced into forming a repeating pattern within the first mask. Portions of the repeating pattern are then removed to form a second mask from the first mask. The patterning of the block copolymer-containing composition may utilize photolithography. Alternatively, the substrate may have regions which wet differently relative to one another with respect to the block copolymer-containing composition, and the patterning of the first mask may utilize such differences in wetting in forming the first mask.Type: GrantFiled: December 1, 2011Date of Patent: March 12, 2013Assignee: Micron Technology, Inc.Inventors: Scott Sills, Dan Millward

Patent number: 8394580Abstract: This invention relates, e.g., to a method for detecting the presence of lymph node metastases in a subject having papillary thyroid carcinoma (PTC), comprising measuring in a sample from the subject the amount of expression (e.g., the amount of protein, or the amount of mRNA encoding the protein) of one or more of the following proteins: (a) LIMD2, and/or (b) PTPRC, and/or (c) LTB, and/or (d) CD48, and/or (e) ABCC3, wherein a significant amount of over-expression of one or more of protein(s) (a)-(e), compared to the baseline value, indicates that lymph node metastases are likely to be present in the subject.Type: GrantFiled: August 18, 2008Date of Patent: March 12, 2013Assignee: The Johns Hopkins UniversityInventors: Gregory Riggins, Janete Cerutti

Patent number: 8394581Abstract: Since FIV-vaccinated cats produce antibodies against FIV, distinguishing them from FIV-infected cats is difficult by serological diagnostic methods using FIV and FIV-derived substances. The present invention enables tests for determining the presence or absence of a FIV vaccination history in a cat by detecting antibodies that are produced as a result of vaccination of a cat with an FIV vaccine, but not as a result of FIV infection. Using the methods of the present invention, whether an anti-FIV antibody-positive cat is infected with FIV or has been vaccinated can be conveniently distinguished.Type: GrantFiled: July 25, 2008Date of Patent: March 12, 2013Assignee: The Kitasato InstituteInventors: Tsutomu Hohdatsu, Kenji Motokawa, Hajime Kusuhara

Patent number: 8394582Abstract: The present invention relates to the identification of fetal specific nucleic acids and fetal cell markers in maternal plasma or serum. In particular, the present invention relates to methods which rely on the analysis of polymorphic alleles of a population to determine an allele which is possessed by the fetus but absent from the mother. Fetal specific alleles identified using the methods of the invention can be used to quantify fetal DNA from maternal plasma or serum. In addition, antigens encoded by alleles identified using the methods of the invention can be targeted in methods of isolating or detecting fetal cells.Type: GrantFiled: March 5, 2004Date of Patent: March 12, 2013Assignee: Genetic Technologies, IncInventor: Ralph Michael Bohmer
