Abstract:
An object of the present invention is to provide an anisotropic conductive bonding member capable of achieving excellent conduction reliability and insulation reliability, a semiconductor device using the same, a semiconductor package, and a semiconductor device production method. An anisotropic conductive bonding member of the present invention includes an insulating base which is made of an inorganic material, a plurality of conductive paths which are made of a conductive member, penetrate the insulating base in a thickness direction thereof, and are provided in a mutually insulated state, and a pressure sensitive adhesive layer which is provided on a surface of the insulating base, in which each of the conductive paths has a protrusion protruding from the surface of the insulating base, the protrusion of each of the conductive paths is buried in the pressure sensitive adhesive layer, and the pressure sensitive adhesive layer contains a polymer material and an antioxidant material.
