Abstract: An acidic gas separation membrane is selectively permeable to an acidic gas, and includes a first porous layer and a resin composition layer formed on the first porous layer with use of a resin composition. The resin composition contains a modified polyamine obtained by introducing at least one of an acidic dissociable group and a salt thereof into a polyamine. The acidic dissociable group is at least one selected from the group consisting of a carboxy group, a sulfonic acid group, an oxysulfonic acid group, a phosphoric acid group, and an oxyphosphoric acid group. The polyamine is at least one selected from the group consisting of polyethyleneimine, polyallylamine, and polyvinylamine.

Abstract: A film for a light emitting device which is useful for producing a light emitting device having excellent luminance life is described. The film contains a cross-linked body of a crosslinkable material having a crosslinking group in an amount of 0.015 mmol/g to 0.05 mmol/g. A light emitting device containing the film is also described. A method for analyzing a crosslinking group in a film for a light emitting device involves: (1) a step of swelling the above-described film for a light emitting device with a solvent, and (2) a step of measuring a crosslinking group of the swollen film for a light emitting device using nuclear magnetic resonance spectroscopy.

Abstract: 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.

Abstract: An insulative coat film comprising one or two or more kinds of oxides having a dielectric constant (k) of 2.5 or smaller and expressed by a general formula of ((CH3)nSiO2-n/2)x(SiO2)1-x (where n=1 to 3, x?1) is used to form an interlayer insulation film. The insulative coat film applied by spin-coating is flat without reflecting underlying unevenness, and the heat-treated film has surface roughness of 1 nm or less in Ra and 20 nm or less in a P-V value. The interlayer insulation film containing the insulative coat film can have a wiring structure and an electrode formed only by etching without need of a CMP process.
