Abstract:
A lithographic apparatus comprising a support structure constructed to support a patterning device and associated pellicle, the patterning device being capable of imparting the radiation beam with a pattern in its cross-section to form a patterned radiation beam, and a projection system configured to project the patterned radiation beam onto a target portion of a substrate, wherein the support structure is located in a housing and wherein pressure sensors are located in the housing.
Abstract:
A lithographic apparatus comprises a system. The system comprises a first part (208), a second part (204) and an energy absorbing element (210). The second part is configured to move relatively to the first part. The system has a gap (216) located between the first part and the second part during an operation mode of the system. The energy absorbing element is for absorbing energy between the first part and the second part when the first part and the second part crash onto each other in a failure mode of the system. The energy absorbing element is outside the gap.
Abstract:
A stage (ST) that is moveable relative to a reference (RE) including: a bearing (BE) to support and guide movement of the stage relative to the reference in a 2D plane; and an actuator system (ACT) to apply forces to the stage relative to the reference to move or position the stage relative to the reference in the 2D plane, wherein the actuator system includes at least one actuator device (CL) configured to have an engaged mode, in which the actuator device is engaged with the stage to allow the stage to move along with the actuator device, and a disengaged mode, in which the actuator device is disengaged from the stage allowing the stage and the actuator device to move independently.
Abstract:
The present invention relates to a fluid handling system. The fluid handling system comprises a liquid confinement structure configured to confine immersion liquid to a space between at least a part of the liquid confinement structure and a surface of a substrate. The fluid handling system also comprises a mechanism configured to vibrate a vibration component in contact with the immersion liquid.
Abstract:
A lithographic apparatus can include an illumination system (IL) that conditions a radiation beam (B), a first stationary plate (412) having a first surface (426), and a reticle stage defining, along with the first stationary plate, a first chamber (404). The reticle stage supports a reticle (402) in the first chamber, and the reticle stage includes a first surface (424) spaced apart from a second surface of the first stationary plate, thereby defining a first gap (414) configured to suppress the amount of contamination passing from a second chamber (406) to the first chamber. The first stationary plate is between the reticle stage and both the illumination system and a projection system (PS) configured to project a pattern imparted to the radiation beam by the patterning device onto a substrate.
Abstract:
Designs are provided to reduce the possibility of contaminant particles with a large range of sizes, materials, travel speeds and angles of incidence reaching a particle-sensitive environment. According to an aspect of the disclosure, there is provided an object stage (400) comprising first and second chambers (403; 405). The object stage further comprises a first structure (402) having a first surface (415) and a second structure (404). The second structure is configured to support an object (412) in the second chamber (405), movable relative to the first structure, and comprises a second surface (417) opposing the first surface (415) of the first structure (402) thereby defining a gap (414) between the first structure and the second structure that extends between the first chamber (403) and the second chamber (405). The object stage further comprises a gas outlet for injecting a gas provided (a) in the gap or (b) in the first chamber adjacent an entrance of the gap at the first chamber.
Abstract:
A positioning system for positioning an object. The positioning system includes a stage, a balance mass and an actuator system. The stage is for holding the object. The actuator system is arranged to drive the stage in a first direction while driving the balance mass in a second direction opposite to the first direction. The stage is moveable in the first direction in a movement range. When the stage is moving in the first direction and is at an end of the movement range, the positioning system is arranged to collide the stage frontally into the balance mass.
