Claim:
1. A method of manufacturing a semiconductor device, comprising: forming a first electrode comprising a metal on a first face of a first semiconductor chip; forming a second electrode comprising a metal, and a protrusion, on a second face of a second semiconductor chip; aligning the first semiconductor chip with the second semiconductor chip such that the first face and the second face face each other; electrically connecting the first semiconductor chip and the second semiconductor chip at a temperature that is higher than a melting point temperature of at least one metal contained in the first electrode and the second electrode in a reflow furnace; and curing the protrusion at a temperature that is lower than the melting point temperature of the metals contained in the first electrode and the second electrode after electrically connecting the first semiconductor chip and the second semiconductor chip in the reflow furnace.
