    Abstract: An anisotropic electrically conductive film includes electrically conductive particles disposed in an electrically insulating adhesive layer. The particles are arranged at a predetermined pitch along first axes, arranged side by side, and are substantially spherical. The particle pitch at the first axes and the axis pitch of the first axes are both greater than or equal to 1.5D, D being an average particle diameter of the particles. Directions of all sides of a triangle formed by a particle (P0), which is one of the electrically conductive particles at one of the first axes, an electrically conductive particle (P1), which is at the one of the first axes and adjacent to the particle (P0), and an electrically conductive particle (P2), which is at another one of the first axes that is adjacent to the one of the first axes, are oblique to a film width direction of the conductive film.

    Abstract: Anisotropic conductive film produced that a light-transmitting transfer die having openings with conductive particles disposed therein is prepared, and photopolymerizable insulating resin squeezed into openings to transfer conductive particles onto the surface of the photopolymerizable insulating resin layer, first connection layer is formed which has a structure in which conductive particles are arranged in a single layer in a plane direction of photopolymerizable insulating resin layer and the thickness of photopolymerizable insulating resin layer in central regions between adjacent ones of the conductive particles is smaller than thickness of photopolymerizable insulating resin layer in regions in proximity to conductive particles; first connection layer is irradiated with ultraviolet rays through light-transmitting transfer die; release film is removed from first connection layer; second connection layer is formed on the surface of first connection layer opposite to light-transmitting transfer die; and third connection layer is formed on the surface of first connection layer.

    Abstract: Anisotropic conductive films, each including an insulating adhesive layer and conductive particles insulating adhesive layer in a lattice-like manner. Among center distances between an arbitrary conductive particle and conductive particles adjacent to the conductive particle, the shortest distance to the conductive particle is a first center distance; the next shortest distance is a second center distance. These center distances are 1.5 to 5 times the conductive particles' diameter. The arbitrary conductive particle, conductive particle spaced apart from the conductive particle by the first center distance, conductive particle spaced apart from the conductive particle by first center distance or second center distance form an acute triangle. Regarding this acute triangle, an acute angle formed between a straight line orthogonal to a first array direction passing through the conductive particles and second array direction passing through conductive particles being 18 to 35□. These anisotropic conductive films have stable connection reliability in COG connection.
