Abstract: There is provided a flip chip mounting process which is high in productivity and reliability, and thus can be applicable to the flip chip mounting of the next-generation LSI. This flip chip mounting process comprises the steps of supplying a resin (13) containing solder powder and a convection additive (12) onto a wiring substrate (10) having a plurality of electrode terminals (11), then bringing a semiconductor chip (20) having a plurality of connecting terminals (11) into contact with a surface of the supplied resin (13), and then heating the wiring substrate (10) to a temperature that enables the solder powder to melt. This heating step is carried out at a temperature higher than the boiling point of the convection additive (12) to allow the boiling convection additive (12) to move within the resin (12). During this heating step, the melted solder powder is allowed to self-assemble into the region between each electrode terminal (11) of the wiring substrate (10) and each connecting terminal (21) of the semiconductor chip to form an electrical connection between each electrode terminal (11) and each connecting terminal (21). Finally, the resin is cured so as to secure the semiconductor chip (20) to the wiring substrate (10).
