Abstract: Disclosed are an optical system, in particular for microlithography, and a method for operating an optical system. According to one disclosed aspect, the optical system includes at least one mirror (100, 500, 600) having an optical effective surface (101, 501, 601) and a mirror substrate (110, 510, 610), wherein at least one cooling channel (115, 515, 615) in which a cooling fluid is configured to flow is arranged in the mirror substrate, for dissipating heat that is generated in the mirror substrate due to absorption of electromagnetic radiation incident from a light source on the optical effective surface, and a unit (135, 535, 635) to adjust the temperature and/or the flow rate of the cooling fluid either dependent on a measured quantity that characterizes the thermal load in the mirror substrate or dependent on an estimated/expected thermal load in the mirror substrate for a given power of the light source.

Abstract: An immersion lithographic apparatus is provided with a liquid confinement structure which defines at least in part a space configured to contain liquid between the projection system and the substrate. In order to reduce the crossing of the edge of the substrate which is being imaged (which can lead to inclusion of bubbles in the immersion liquid), the cross-sectional area of the space in a plane parallel to the substrate is made as small as possible. The smallest theoretical size is the size of the target portion which is imaged by the projection system. In an embodiment, the shape of a final element of the projection system is also changed to have a similar size and/or shape in a cross-section parallel to the substrate to that of the target portion.

Abstract: In a lithographic projection apparatus, a liquid supply system maintains liquid in a space between the projection system and the substrate. The liquid supply system may further include a de-mineralizing unit, a distillation unit, a de-hydrocarbonating unit, a UV radiation source, and/or a filter configured to purify the liquid. A gas content reduction device may be provided to reduce a gas content of the liquid. A chemical may be added to the liquid using an adding device to inhibit lifeform growth and components of the liquid supply system may be made of a material which is non-transparent to visible light such that growth of lifeforms may be reduced.

Abstract: 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.
