Abstract: A laser beam delivery apparatus of an extreme ultra violet light source may include a high power seed module configured to generate a laser beam, a power amplifier configured to amplify the laser beam generated by the high power seed module, a beam transfer module configured to collect and move the laser beam amplified by the power amplifier, a final focusing assembly optical platform configured to adjust focus of the laser beam collected and moved by the beam transfer module, and a focusing unit configured to focus the laser beam with the focus adjusted by the final focusing assembly optical platform to a target droplet. The power amplifier may include a position adjuster configured to adjust a position of the laser beam. The position adjuster may include a refraction plate having a flat surface. The power amplifier may include a pointing adjuster, which may include a mirror.

Abstract: A wafer inspection apparatus includes: an objective lens on an optical path of first and second input beams; and an image sensor configured to generate an image of the wafer based on scattered light according to a nonlinear optical phenomenon based on the first and second input beams, wherein the first input beam passing through the objective lens is obliquely incident on the wafer at a first incident angle with respect to a vertical line that is normal to an upper surface of the wafer, the second input beam passing through the objective lens is incident on the wafer at a second incident angle oblique to the vertical line that is normal to the upper surface of the wafer, and the first and second incident angles are different from each other.

Abstract: A substrate inspection apparatus includes a light source unit, a pulsed beam matching unit, a substrate support unit, an incidence angle adjusting unit, and a detecting unit. The light source unit emits a first laser beam having a first wavelength and a second laser beam having a second wavelength. The pulsed beam matching unit matches the first laser beam and the second laser beam to superimpose a pulse of the first laser beam on a pulse of the second laser beam in time and space. The substrate support unit supports a substrate to be inspected. The incidence angle adjusting unit adjusts angles of incidence of the matched first laser beam and second laser beams to irradiate the first laser beam and the second laser beam on the substrate, and mixes the first laser beam and the second laser beam to generate an evanescent wave on the substrate. The evanescent wave generates scattered light due to a defect of the substrate. The detecting unit detects the scattered light generated due to the defect of the substrate.
