Systems, apparatuses, and methods are provided for removing heat from a reticle. An example method can include generating, by a cooling controller, a cooling control signal based on timing data for a projection of a patterned radiation beam formed by illuminating an exposed area on a reticle supported by a reticle table, absorption data for the exposed area, and a target heat transfer rate. The cooling control signal can instruct a reticle cooling apparatus to actuate actuators to modify a distance between the reticle and a roof of the reticle cooling apparatus. The method can further include modifying, by the actuators based on the cooling control signal, the distance between the reticle and the roof to modify a heat transfer rate associated with a removal of heat from the reticle towards the target heat transfer rate.

A method of protecting a component of a lithographic apparatus, the method including the steps of: providing a protective cover which is shaped to protect at least part of said component, the protective cover having a contact surface which is arranged to adhere to a first surface of at least part of said lithographic apparatus or said component; and bringing the protective cover into proximity with the component so as to cause the contact surface to adhere to the lithographic apparatus or said component and remain adhered without the application of external force. It is also provided a patterning device for use in a lithographic apparatus and a lithographic apparatus.

A reticle conditioning system includes: a support structure to support a reticle; a gas supply module to provide a flow of gas adjacent to the reticle; and a biasing module to control an electrical potential of the reticle. The biasing module includes a first electrode, a second electrode and a voltage supply. The first and second electrodes are each spaced apart from and facing the reticle, when the reticle is supported by the support structure, so as to at least partially overlap with the reticle. The voltage supply is arranged to maintain the first electrode at a positive voltage, and the second electrode at a negative voltage, these voltages being such that the voltage of the reticle is negative. The second electrode is disposed such that, when the reticle is supported by the support structure, it does not overlap an image forming portion of the reticle.

Provided is an optical element for a lithographic apparatus. The optical element includes a capping layer that includes oxygen vacancies therein. The oxygen vacancies prevent attack of the capping layer by preventing hydrogen and other species from penetrating the capping layer and underlying layers. The capping layer provides a low hydrogen recombination rate enabling hydrogen to clean the surface of the optical element. The capping layer may include an alloyed metal, a mixed metal oxide or a doped metal oxide and it may be a ruthenium capping layer that includes one or more dopants therein.

Oxygen-loss resistant top coating for optical elements

An EUV collector mirror has a reflection surface () to reflect usable EUV light which impinges on the reflection surface () from a source region () to a subsequent EUV optics. The reflection surface () carries a pump light grating structure () configured to retroreflect pump light () which impinges upon the pump light grating structure () from the source region () back to the source region (). The pump light () has a wavelength deviating from the wavelength of the usable EUV light. Such EUV collector mirror enables a high conversion efficiency between the energy of pump light of a laser discharged produced plasma (LDPP) EUV light source on the one hand and the resulting usable EUV energy on the other.
