A lithographic apparatus is disclosed that includes a first gas shower configured to supply a first gas flow to an interior space of the apparatus, and a second gas shower configured to supply a second gas flow to the interior space of the apparatus, the gas showers configured to direct the first gas flow and the second gas flow at least partly towards each other. Also, a method for conditioning an interior space of a device manufacturing apparatus is provided that includes supplying a first conditioned gas flow and a second conditioned gas flow to the interior space, such that the first conditioned gas flow and the second conditioned gas flow are at least partly directed to each other.
摘要:
A gas shower to condition at least one optical path in an optical apparatus, wherein the gas shower includes a gas distribution chamber having a shower outlet side to supply gas to the optical path, the gas distribution chamber being configured to distribute the gas to the optical path, wherein the gas distribution chamber includes a substantially sharp tapered tip.
摘要:
A lithographic apparatus includes a support constructed to support a patterning device that is capable of imparting a radiation beam with a pattern in its cross-section to form a patterned radiation beam, a substrate table constructed to hold a substrate, a projection system configured to project the patterned radiation beam onto a target portion of the substrate, an interior space through which an interferometer beam propagates, and a first gas supply for supplying a purge gas to inhibit contamination of the projection system. The purge gas has a predetermined refractive index. The apparatus also includes a second gas supply for supplying a conditioning gas to the interior space for conditioning the interior space, and a refractive index matching system arranged to match the refractive index of the conditioning gas to the predetermined refractive index of the purge gas.
摘要:
An immersion lithographic projection apparatus is disclosed. The apparatus includes a substrate table for holding a substrate and a liquid supply system for supply liquid to the substrate. The apparatus is constructed and arranged to allow the liquid to flow off the substrate and over at least two edges of a top surface of the substrate table. The geometry of the edge may be optimized to reduce a static thickness of a layer of liquid on the top surface.
摘要:
A lithographic apparatus includes a measurement system to measure the position and/or movement of a substrate support relative to a reference frame. The measurement system includes a target mounted to one of the substrate support and the reference frame, a radiation source mounted to the other one of the substrate support and the reference frame and a sensor configured to detect a pattern of radiation propagating from the target, indicating the position or movement of the substrate support. The substrate support includes one or more gas outlets configured to provide a flow of gas that encapsulates the volume of space through which the beam of radiation propagates to the target.
摘要:
A gas manifold to direct a gas flow between two plates of an optical component of a lithographic apparatus, the gas manifold having an inlet, a diffuser downstream of the inlet, a flow straightener downstream of the inlet, a contractor downstream of the flow straightener, and an outlet downstream of the contractor.
摘要:
A fluid handling structure configured to supply and confine immersion liquid to a space defined between a projection system and a facing surface facing the fluid handling structure is disclosed. The fluid handling structure includes a supply passage formed therein for the passage of fluid from outside the fluid handling structure to the space, and a thermal isolator positioned adjacent the supply passage at least partly to isolate fluid in the supply passage from a thermal load induced in the fluid handling structure.
摘要:
A liquid handling system is disclosed in which an extractor to contain liquid in a space between the projection system of a lithographic apparatus and a substrate has, in plan, a shape with a single corner. The extractor is provided in a rotatable part of a liquid handling system. The rotatable part is rotated under the control of a controller.
