Abstract:
A method for producing a semiconductor device includes a step of bonding a chip to a SOI wafer, the chip being formed of a III-V group compound semiconductor and including a substrate and a first semiconductor layer; and a step of removing the substrate and the first semiconductor layer from the chip after the step of bonding. In the producing method, the first semiconductor layer has a tensile strain, and the SOI wafer and the chip are heated to a first temperature in the step of bonding, and are cooled to a second temperature lower than the first temperature after the step of bonding.
