Patent ID: 7863101

Claim:
A method of producing a stacked semiconductor device having a first-layer semiconductor device and a second-layer semiconductor device formed by being staked on each other, comprising the steps of: disposing the second-layer semiconductor device on the first-layer semiconductor device which is warped providing, between a first-layer semiconductor device and a second-layer semiconductor device, solder and a thermosetting resin for bonding the first-layer semiconductor device and the second-layer semiconductor device; heating the first-layer semiconductor device and the second-layer semiconductor device to a first temperature at which the first-layer semiconductor device has a flat shape to cure the thermosetting resin; heating the first-layer semiconductor device and the second-layer semiconductor device to a second temperature which is higher than the first temperature to melt the solder; and cooling the first-layer semiconductor device and the second-layer semiconductor device to solidify the solder.
