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, wherein the underfill material contains a phenoxy resin, an epoxy resin, a curing agent, a (meth)acrylate resin and an organic peroxide, and a time for a reaction rate to reach 20% at 240° C. calculated by Ozawa method using a differential scanning calorimeter is 2.0 sec or less and a time for the reaction rate to reach 60% is 3.0 sec or more.
