Method of mounting a semiconductor chip, circuit board for flip-chip connection and method of manufacturing the same, electromagnetic wave readable data carrier and method of manufacturing the same, and electronic component module for an electromagnetic wave readable data carrier

Abstract

To provide a semiconductor chip mounting method by a flip-chip connection method in which a semiconductor chip can be mounted on a circuit board promptly, electrically and mechanically surely and further at a low cost, a process for pushing a melted thermoplastic resin coat aside by pressing a bump of the bare semiconductor chip on the melted thermoplastic resin coat applying an ultrasonic wave in a state in which the thermoplastic resin coat covering an electrode area on a wiring pattern is heated and melted and touching the bump and the electrode area, a process for bonding the bump and the electrode area by continuously applying an ultrasonic wave in a state in which the bump and the electrode area are touched and a process for cooling and solidifying the melted thermoplastic resin coat and bonding the body of the bare semiconductor chip on the circuit board are provided.
