Abrégé
A high adhesive strength and good conduction reliability can be realized when anisotropic connection is performed under compression conditions of a compression temperature of 130° C. and a compression time of 3 seconds using an anisotropic conductive film which uses a polymerizable acrylic compound capable of being cured at a comparatively lower temperature and in a comparatively shorter time than a thermosetting epoxy resin along with a film-forming resin. Consequently, an anisotropic conductive film has a structure in which an insulating adhesive layer and an anisotropic conductive adhesive layer are laminated. The insulating adhesive layer and the anisotropic conductive adhesive layer each contain a polymerizable acrylic compound, a film-forming resin, and a polymerization initiator. The polymerization initiator contains two kinds of organic peroxide having different one minute half-life temperatures. Of the two kinds of organic peroxide, the organic peroxide having the higher one minute half-life temperature produces benzoic acid or a derivative thereof by decomposition.

Disclosed is a transparent electrode sheet which suppresses the precipitation of oligomers without forming a coating layer or an applied layer on the PET surface of the adhesive layer. To avoid heat shrinkage during annealing in the manufacturing process, a touch panel is pre-annealed by heat shrinking the first and second resin films (1, 2) prior to annealing. As a result of having been pre-annealed, when the first and second resin films (1, 2) are heated above glass transition temperature the oligomers within said films are precipitated and disperse. The oligomers, which pass from the resin films (1, 2), along the boundary surface between the films (1, 2) and the adhesive layer (3) and move to the adhesive layer (3), mix with said layer, made from polyethylene containing terephthalic acid and ethylene glycol, and are not precipitated as crystals. Even if the oligomers do not mix with the adhesive layer (3), the light refraction indexes of the oligomers and said layer (3) are almost equal and so the oligomers are not visible.

A method of producing a semiconductor device in which a semiconductor chip is flip-chip mounted on a board with a non-conductive resin film (NCF), wherein said method prevents the NCF from protruding at the time of hot pressing, prevents non-conductive resin and inorganic filler from entering the space between the bumps and the electrode pads, and wherein the acquired semiconductor device exhibits sufficient moisture/reflow resistance. Specifically, the NCF has a size equivalent to 60 to 100% of the area of a region enclosed by a plurality of bumps that are arranged at the periphery of a semiconductor chip and has a minimum melt viscosity of 2×102 to 1×105 Pa⋅s. The NCF is temporarily bonded to a region enclosed by a plurality of electrodes of the board which correspond to the bumps. Next, the semiconductor chip and board are positioned so that the bumps and the corresponding electrodes face each other, and are hot pressed from the semiconductor chip side. This causes the bumps and the electrodes to metallically bond, and melts and further thermally hardens the NCF. Due to this, a semiconductor device is acquired.

An image display device has an image display part and a protective part on the image display part. The image display device suppresses image unevenness and cured resin peeling caused by internal stress generated due to curing shrinkage of a cured resin between the protective part and the image display part or external stress applied on the image display part due to warping of the protective part. A cured resin layer is arranged between the image display part and the protective part. The cured resin layer has a light transmittance in the visible region of 90% or more, an elongation ratio of 700% or more at 25° C. and 400% or more at 80° C., and an adhesive force with respect to the protective part of 0.4 N/cm or more at 25° C. and 0.3 N/cm or more at 80° C.

The present invention aims to sufficiently suppress bleedout of a cyclic dimethylsiloxane oligomer, which is an impurity, from a thin protective layer which is obtained by forming, patterning and curing a film of a photosensitive siloxane polyimide resin composition on a printed wiring board. For fulfilling the aim, the photosensitive siloxane polyimide resin composition contains: 100 parts by mass of a siloxane polyimide resin which is obtained by imidizing a tetracarboxylic acid dianhydride, a siloxane diamine having a diphenylsilylene unit and a diamine containing no siloxane; 1-20 parts by mass of at least one kind of crosslinking agent selected from the group consisting of liquid epoxy resins, benzoxazines and resols; and 5-30 parts by mass of a photoacid generator.

A radical-polymerizable acrylic dielectric adhesive for NCF bonding of an electronic device to a wiring board, which comprises a (meth)acrylate monomer, a film-forming resin, an inorganic filler, a silane coupling agent, and a radical polymerization initiator. The content of the inorganic filler is 70 to 160parts by mass per 100 parts by mass of the sum total of the (meth)acrylate monomer and the film-forming resin. A radical-polymerized and cured product of the acrylic dielectric adhesive has a glass transition temperature of 150 to 185°C and exhibits a linear expansion coefficient (α1) of 30 to 35ppm in the temperature range below the glass transition temperature and a linear expansion coefficient (α2) of 105 to 125ppm in the temperature range not lower than the glass transition temperature. The (α2)/(α1) ratio is 3.4 or above.

Abrégé
A method for connecting an electronic part, which contains: mixing a dispersing solvent, an adhesive resin which is dissolved in the dispersing solvent, conductive particles, and insulating particles which have smaller particle diameters than those of the conductive particles so as to prepare an anisotropic conductive adhesive; placing a terminal of a substrate and a terminal of an electronic part so as to face each other via the anisotropic conductive adhesive, and applying heat and pressure to the substrate and the electronic part so as to sandwich the conductive particles between the terminal of the substrate and the terminal of the electronic part to thereby deform the conductive particles, in which the pressure is smaller than pressure at which the conductive particles are destroyed, and smaller than pressure at which the particle diameters of the conductive particles become equal to the particle diameters of the insulating particles.
