Abstract:
A chamber device according to one aspect of the present disclosure includes a chamber inside which plasma is generated, a light source, and an incidence window configured to transmit light emitted from the light source to the inside of the chamber. The incidence window includes a first surface facing the outside of the chamber, and a second surface facing the inside of the chamber. At least the second surface is not coated with an anti-reflection film. The second surface is disposed in a state of being inclined at a non-perpendicular angle against an optical axis of the light emitted from the light source.

Claim (Index 20):
An ultraviolet light generating device comprising:\n a chamber inside which plasma is generated; a light source disposed outside the chamber; an incidence window configured to transmit light emitted from the light source to an inside the chamber; an emission window configured to transmit the light emitted from the light source and passing through the inside of the chamber, from the inside of the chamber to an outside of the chamber; a light receiving unit disposed outside the chamber beyond the emission window, the light receiving unit being configured to receive the light passing through the inside of the chamber and emitted from the emission window; a target feeding unit configured to feed a droplet of a target substance, serving as a source of generating the plasma, to the inside of the chamber; and a laser light introduction window configured to transmit laser light to be radiated to the droplet and introduce the laser light into the chamber, the incidence window having a first surface facing the outside of the chamber and a second surface facing the inside of the chamber and exposed to plasma light, at least the second surface out of the first surface and the second surface being not coated with an anti-reflection film, the second surface being disposed on a wall of the chamber in a state of being inclined at a non-perpendicular angle against an optical axis of the light emitted from the light source and passing through the incidence window, the emission window including a third surface facing the inside of the chamber and exposed to the plasma light and a fourth surface facing the outside of the chamber, at least the third surface out of the third surface and the fourth surface being not coated with an anti-reflection film, the third surface being disposed on a wall of the chamber in a state of being inclined at a non-perpendicular angle against the optical axis of the light emitted from the light source and passing through the emission window, and a target of the droplet, supplied from the target feeding unit into the chamber, being irradiated with the laser light and made into plasma to thereby generate extreme ultraviolet light.
