Method for connecting electronic components, method for forming bump and conductive connection film and fabrication apparatus for electronic component mounted body, bump and conductive correction film |
摘要 |
A liquid resin in which conductive particles are dispersed is supplied to between a circuit substrate and a semiconductor chip disposed so as to face each other and an ultrasonic wave having an amplitude in a perpendicular direction to a surface of the circuit substrate to generate a standing wave in a resin. Then, the conductive particles dispersed in the resin are captured at nodes of the standing wave to form connection bodies of aggregation of the conductive particles between connection terminals of the semiconductor chip and terminals of the circuit substrate. Thus, the semiconductor chip is mounted on the circuit substrate via the connection bodies. The terminals are arrayed so as to be spaced apart from one another by half a wavelength of the standing wave and each of the nodes of the standing wave are generated at a position between the terminals in the resin.
