Abstract:
1. A method for manufacturing a mounted body, the method comprising the steps of: providing a solder resin paste between a multilayer semiconductor chip comprising a plurality of semiconductor chips that are stacked and a mounting board on which the multilayer semiconductor chip is mounted including areas where a solder bump is not to be formed, the solder resin paste containing a resin, a solder powder, and a convection additive that boils when heated; and heating the solder resin paste so that motion of the boiling convection additive in the resin gives kinetic energy to solder particles dispersed in the resin to promote a movement of the solder particles, thus causing the solder powder to assemble to form the solder bump, whereby an element electrode of each semiconductor chip of the multilayer semiconductor chip and an electrode terminal formed on the mounting board so as to correspond to the element electrode are connected electrically to each other collectively.
