Abstract:
1. A substrate processing device, comprising: a chamber; a stage which is provided in said chamber and on which a substrate is placed; a process gas supplier which supplies into said chamber a process gas which reacts with a material of the substrate and thus can convert the material into a gaseous substance; and a laser light irradiator which includes a light source oscillating a laser light having a predetermined wavelength that is absorbable by the material and not absorbable by the process gas and a light irradiating unit connected to said light source, said laser light being irradiated to a predetermined portion of the substrate and being prevented from changing during passing through a transferring path from said light source to said light irradiating unit, without being degenerated by the process gas, so that the material at said predetermined portion is excited and then converted into the gaseous substance by reacting with the process gas.
