摘要:
In a lithographic apparatus, a localized area of the substrate surface under a projection system is immersed in liquid. The height of a liquid supply system above the surface of the substrate can be varied using actuators. A control system uses feedforward or feedback control with input of the surface height of the substrate to maintain the liquid supply system at a predetermined height above the surface of the substrate.
摘要:
A substrate table of an immersion lithographic apparatus is disclosed which comprises a barrier configured to collect liquid. The barrier surrounds the substrate and is spaced apart from the substrate. In this way any liquid which is spilt from the liquid supply system can be collected to reduce the risk of contamination of delicate components of the lithographic projection apparatus.
摘要:
A method and apparatus for cleaning the inside of an immersion lithographic apparatus is disclosed. A cleaning device may be provided in the substrate table and an ultrasonic emitter may be provided to create an ultrasonic cleaning liquid.
摘要:
A method and apparatus for cleaning the inside of an immersion lithographic apparatus is disclosed. In particular, a liquid supply system of the lithographic apparatus may be used to introduce a cleaning fluid into a space between the projection system and the substrate table of the lithographic apparatus. Additionally or alternatively, a cleaning device may be provided on the substrate table and an ultrasonic emitter may be provided to create an ultrasonic cleaning liquid.

摘要:
An immersion lithographic apparatus is disclosed which includes a liquid supply system having an inlet configured to supply a liquid to a space between a projection system of the lithographic apparatus and a substrate and an outlet configured to remove at least part of the liquid, the liquid supply system configured to rotate the inlet, the outlet, or both, about an axis substantially perpendicular to an exposure plane of the substrate.
