ANISOTROPIC CONDUCTIVE FILM, SEMICONDUCTOR DEVICE USING THE FILM, AND ITS MANUFACTURING METHOD

摘要

PROBLEM TO BE SOLVED: To provide an anisotropic conductive film capable of stably connecting a semiconductor element to a wiring substrate even if pressure by the application of pressure is varied, and provide a semiconductor device using the anisotropic conductive film and the manufacturing method for the semiconductor device. SOLUTION: A plurality of conducting members 12 are installed on the inside of a film substrate 13 made of an insulating material, and in each conducting member 12, a first electrode 11 formed on a first surface of the film substrate 13 and a second electrode 14 formed on a second surface of the film substrate 13 are electrically connected, and a tapered projection 10 is formed in at least a part of the surface of the electrode 11 and a tapered projection 15 is formed in at least a part of the surfaces of the electrode 14.
