摘要:
An illumination system is disclosed that had a plurality of moveable reflective elements and associated actuators which may be configured to form an illumination mode. One or more of the actuators is arranged to move between first, second and third positions, and so move an associated moveable reflective element between first, second and third orientations, the first and second orientations being such that radiation reflected from the moveable reflective element forms part of the illumination mode, and the third orientation being such that radiation reflected from the moveable reflective element does not form part of the illumination mode.
摘要:
In a lithographic printing process a substrate is moved, in the scanning direction, relative to a patterned beam of radiation being projected onto it during a scanning exposure of a pattern feature. An image of the pattern feature is blurred in the scanning direction. The effect of the blurring is used to reduce a difference of critical dimension between similar horizontal and vertical features. The effect on critical dimension may be obtained by providing an amount of anamorphic magnification to the projection system.
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:
An apparatus and method for imaging a pattern onto a substrate is described. A recipe for producing an image includes optional tool-type information. Where tool-type information indicates that the recipe pertains to a different tool type, the apparatus makes adjustments to its imaging settings in order to emulate performance of the different tool type.
