Publication number: 20120168053Abstract: A method for producing a flexible metal laminate includes continuously thermocompression-bonding laminate metal foils to a resin film. The thermocompression-bonding step is conducted by placing a protection metal foil between a pressure surface of a heat and pressure forming apparatus and the laminate metal foils. When the protection metal foil is subjected to an abrasion resistance test, in which the protection metal foil is placed such that a matte surface of the protection metal foil contacts a plate material having a surface equivalent to the pressure surface and in which the matte surface is rubbed against the surface of the plate material by applying a load to a shiny surface of the protection metal foil and pulling the protection metal foil, a streak is found on the matte surface only in a case where the load is over 500 g per area of 76 mm×26 mm.Type: ApplicationFiled: September 9, 2010Publication date: July 5, 2012Applicants: UBE-NITTO KASEI CO., LTD., UBE INDUSTRIES, LTDInventors: Takuro Kochiyama, Hiroto Shimokawa, Yoshitaka Mineki, Masami Sasaki

Publication number: 20110215384Abstract: In manufacturing processes of a semiconductor device including a shallow trench element isolation region and an interlayer insulating film of a multilayer structure, it is necessary to repeatedly use CMP, but since the CMP itself is costly, the repeated use of the CMP is a cause to increase the manufacturing cost. As an insulating film for use in a shallow trench (ST) element isolation region and/or a lowermost-layer interlayer insulating film, use is made of an insulating coating film that can be coated by spin coating. The insulating coating film has a composition expressed by ((CH3)nSiO2-n/2)x(SiO2)1-x(where n=1 to 3 and 0?x?1.0) and a film with a different relative permittivity k is formed by selecting heat treatment conditions. The STI element isolation region can be formed by modifying the insulating coating film completely to a SiO2 film, while the interlayer insulating film with a small relative permittivity k can be formed by converting it to a state not completely modified.Type: ApplicationFiled: August 14, 2008Publication date: September 8, 2011Applicants: National University Corporation Tohoku University, Tokyo Electron Limited, Ube Industries, Ltd., Ube-Nitto Kasei Co., Ltd.Inventors: Tadahiro Ohmi, Takaaki Matsuoka, Atsutoshi Inokuchi, Kohei Watanuki, Tadashi Koike, Tatsuhiko Adachi
