Method of fabricating semiconductor device

Image Number 3 for United States Patent #8426285.

An ion implantation is performed to implant ions into a silicon substrate, and a microwave irradiation is performed to irradiate the silicon substrate with microwaves after the ion implantation. After the microwave irradiation, the silicon substrate is transferred to a heat-treatment apparatus, where the silicon substrate is treated with heat by being irradiated with light having a pulse width ranging from 0.1 milliseconds to 100 milliseconds, both inclusive.
