  • Patent number: 10976668
    Abstract: An illumination optical unit for EUV projection lithography serves for obliquely illuminating an illumination field, in which an object field of a downstream imaging catoptric optical unit and a reflective object to be imaged can be arranged. A pupil generating device of the illumination optical unit is embodied so that an illumination pupil results, which brings about a dependency of an imaging telecentricity against a structure variable of the object to be imaged. This dependency is such that a dependency of the imaging telecentricity against the structure variable of the object to be imaged on account of interaction of the oblique illumination with structures of the object to be imaged is at least partly compensated for. An optical system for EUV projection lithography also has an imaging catoptric optical unit alongside an illumination optical unit and can additionally have a wavefront manipulation device.

  • Patent number: 10798808
    Abstract: Examples of systems for forming cavity and a liquid liner are described. The system comprises a vessel and a rotating member positioned within the vessel and rotatable about an axis of rotation. The rotating member has an inner surface 5 curved with respect to the axis of rotation, an outer and plurality of fluid passages that each has an inboard opening at the inner surface and an outboard opening at the outer surface. The rotating member is filled with a liquid medium and a rotational driver rotates the rotating member such that when rotating the liquid medium at least partially fills the fluid passages forming liquid liner, defining the 10 cavity. The cavity formation system is used in a liquid liner implosion system with an implosion driver that causes the liquid liner to implode inwardly collapsing the cavity. The imploding liquid liner system can be used in plasma compression systems.

  • Publication number: 20200236770
    Abstract: Examples of systems for imploding liquid liner are described. The imploding system comprises a vessel and a rotating member positioned within the vessel. The rotating member has a plurality of shaped blades that form a plurality of curved passages that have an inboard opening at an inner surface and an outboard end at an outer surface. The rotating member is at least partially filled with liquid medium. A driver is used to rotate the rotating member such that when the rotating member rotates the liquid medium is forced into the passages forming a liquid liner with an interface curved with respect to an axis of rotation and defining a cavity. The system further comprises an implosion driver that changes the rotational speed of the rotating member such that the liquid liner is imploded inwardly collapsing the cavity. The imploding liquid liner can be used in plasma compression systems.
