Abstract: PURPOSE:To reduce the contact resistance thereby improving the reliability by a method wherein the bumps of a semiconductor element are prepressurized and then the semiconductor element and a substrate are pressure-bonded to each other to bring the bumps of semiconductor element and the electrode parts of substrate into contact with one another for setting the bonding resin. CONSTITUTION:Conductive bumps protruding from the surface of a semiconductor element 10 are provided on the electrode parts of the semiconductor element 10 to be once pressed against the plane of a rigid body (quartz plate) 3 and at least one of a substrate 20 or the semiconductor element 10 is coated with bonding resin and after pressurizing the semiconductor element 10 and the substrate 20 to be bonded to each other to bring the bumps and electrode patterns into contact with one another, the bonding resin is set. Thus, the bumps provided on the electrode parts of the semiconductor element 10 are pressed against the plane of the rigid body 3 to improve the evenness of height and the flatness of bump surface. The bumps and the electrode patterns of substrate are pressurized to be made conductive while the semiconductor element 10 and the substrate 20 are bonded to each other by the bonding resin. Through these procedures, the contact resistance can be reduced thereby improving the reliability.
