Patent ID: 11309270

Abstract:
An anisotropic conductive film has first and second connection layers formed on a first layer surface. The first connection layer is a photopolymerized resin layer, and the second is thermo- or photo-cationically, anionically, or radically polymerizable resin layer. On the surface of the first connection layer on a second connection layer side, conductive particles for anisotropic conductive connection are in a single layer. The first connection layer has fine projections and recesses in a surface. An anisotropic conductive film of another aspect has first, second, and third connection layers layered in sequence. The first layer formed of photo-radically polymerized resin. The second and third layers are formed of thermo-cationically or thermo-anionically polymerizable resin, photo-cationically or photo-anionically polymerizable resin, thermo-radically polymerizable resin, or photo-radically polymerizable resin. On a surface of the first connection layer on a second connection layer side, conductive particles for anisotropic conductive connection are in a single layer.
