Claim:
1. A method for manufacturing a semiconductor device comprising: a mounting step of mounting a semiconductor chip onto an electronic component, the semiconductor chip having a solder-tipped electrode formed thereon and an underfill material applied to the surface of the solder-tipped electrode, and the electronic component having a counter electrode facing the solder-tipped electrode, and a thermocompression bonding step of thermally compressing the semiconductor chip and the electronic component by increasing a temperature at a predetermined rate from a first temperature to a second temperature, wherein the underfill material contains an epoxy resin, a curing accelerator, a (meth)acrylate resin and an organic peroxide, the minimum melt viscosity of the underfill material ranges from 1000 Pa*s to 2000 Pa*s, and the gradient of the melt viscosity from a temperature 10° C. higher than a minimum melt viscosity attainment temperature to a temperature 10° C. higher than the temperature ranges 900 Pa*s/° C. to 3100 Pa*s/° C.
