Patent number: 7772344Abstract: It is an object of the present invention to provide a composition capable of forming an insulating film which is endowed with a low dielectric constant, heat resistance, chemical resistance and a high mechanical strength that enables the insulating film to withstand CMP, and which, when an inorganic insulating film layer is provided thereon as an overlying layer, has a high adherence thereto. The composition for forming an insulating film contains polyphenylene, wherein the polyphenylene in an insulating film formed from the composition has a number of carbon atoms (C) and a number of oxygen atoms (O) which together satisfy a condition O/(C+O)?0.050. With the composition, the above object is attained.Type: GrantFiled: September 22, 2008Date of Patent: August 10, 2010Assignee: FUJIFILM CorporationInventor: Haruki Inabe

Patent number: 7754837Abstract: Disclosed are telechelic fluoropolymers and methods for forming the polymers. The fluoropolymers can be formed via step-growth polymerization of bis(trifluorovinyloxy)biphenyls with bisphenols. The formed telechelic polymers possess fluoroolefin functionality at the trifluorovinyl aromatic ether endgroups. Internal groups can include difluorodioxyvinylene groups and trifluoroethyl groups. Formation methods of the telechelic polymers can be controlled so as to control molecular weight and degree of unsaturation of the polymers. The end groups and the internal groups can be further reacted independently of each other, e.g., under different temperature conditions, to form a variety of polymers and/or crosslinked polymeric networks.Type: GrantFiled: March 7, 2008Date of Patent: July 13, 2010Assignee: Clemson University Research FoundationInventors: Dennis W. Smith, Jr., Scott T. Iacono
