Abstract: A lithographic projection apparatus is disclosed in which a space between the projection system and the substrate is filled with a liquid. An edge seal member at least partly surrounds the substrate or other object on a substrate table to prevent liquid loss when edge portions of the substrate or other object are, for example, imaged or illuminated.

Abstract: In order to improve the productivity of a lithographic apparatus, a stage apparatus for holding two patterning devices is described. The patterning devices are arranged such that the distance between the patterns in the scanning direction corresponds to the length of the pattern in the scanning direction. By doing so, an improved exposure sequence may be performed by exposing a first die with a first pattern, skipping a second die adjacent to the first die, and exposing a third die adjacent to the second die using a second pattern.

Abstract: A lithographic apparatus includes an illumination system configured to provide a beam of radiation, a support configured to support a patterning device, a substrate table and a projection system. Furthermore, the lithographic apparatus includes a plurality of EUV sources for providing EUV radiation to the illumination system and a distributor which is arranged to convert the EUV radiation from each of the EUV sources into an intermediate beam of radiation. The intermediate beam of radiation is directed from the distributor in a first direction by a mirror surface. The distributor may include a rotationally driven mirror arrangement, the axis of rotation being non-parallel to the mirror surface.

Abstract: A lithographic apparatus includes an illumination system configured to provide a beam of radiation and projection system configured to project the radiation beam onto a target portion of a substrate. At least one of the illumination system and the projection system includes a focusing element for reflecting or refracting the beam. A plurality of stop discs is provided, each having an aperture therethrough, together with a disc positioner configured to place one of the stop discs adjacent the focusing element to control the numerical aperture (NA) of the projection system or illumination system. The apparatus further includes a disc changer configured to select one of the stop discs and provide the selected stop disc to the disc positioner, the disc changer being external to the projection system or illumination system.

Abstract: A lithographic apparatus includes a projection system mounted on a reference frame, which in turn is mounted on a base which supports the apparatus. Vibrations and displacement errors in the base are filtered through two sets of isolation mounts operatively between the base and reference frame and between the reference frame and a projection frame of the projection system and therefore disturbance of the projection system is reduced.

Abstract: A method using a lithographic apparatus comprising a reflective integrator is claimed that optimizes the exposure of features on a target area of a substrate, when the features make an angle between 5 and 85 degrees with respect to the target area. The method comprises rotating the reflective integrator with respect to the target area providing a rotated mirror-symmetric pupil shape, which is implemented by either rotating the substrate or rotating the reflective integrator with respect to the machine or the patterning device. The patterning device comprises a maximum usable area and a patterned area which are rotated with respect to each other if a rotated substrate is employed. The method can be used in single exposure or double exposure mode. A further advantage of the method of using a rotated wafer is that it can be used for exposing features on a substrate in any direction even when the projection system of the lithographic apparatus shows a preferred polarization direction.

Abstract translation: 要求使用包括反射积分器的光刻设备的方法，当特征相对于目标区域形成5至85度的角度时，可优化基板目标区域上的特征的曝光。 该方法包括使反射积分器相对于目标区域旋转，从而提供旋转的对称瞳孔形状，其通过旋转基底或相对于机器或图案形成装置旋转反射积分器来实现。 如果使用旋转的衬底，则图案形成装置包括相对于彼此旋转的最大可用面积和图案化区域。 该方法可用于单次曝光或双曝光模式。 使用旋转晶片的方法的另一个优点是，即使当光刻设备的投影系统显示优选的偏振方向时，其可以用于在任何方向上曝光衬底上的特征。

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.
