Abstract
An ion generator vessel can be filled up with raw material gas containing a specific gas component. The ion generator vessel can be irradiated with a laser beam from a laser oscillator. Due to the beam which is applied into the ion generator vessel, only the specific gas component is selectively excited by multi-photon absorption, to generate ions. Thus, a semiconductor substrate can be inhibited from damage in ion implantation, and processability such as the throughput etc. can be improved.
