    摘要: An immersion lithography apparatus has a reticle stage arranged to retain a reticle, a working stage arranged to retain a workpiece, and an optical system including an illumination source and an optical element opposite the workpiece for having an image pattern of the reticle projected by radiation from the illumination source. A gap is defined between the optical element and the workpiece, and a fluid-supplying device serves to supply an immersion liquid into this gap such that the supplied immersion liquid contacts both the optical element and the workpiece during an immersion lithography process. A cleaning device is incorporated for removing absorbed liquid from the optical element during a cleanup process. The cleaning device may make use of a cleaning liquid having affinity to the absorbed liquid, heat, a vacuum condition, ultrasonic vibrations or cavitating bubbles for the removal of the absorbed liquid. The cleaning liquid may be supplied through the same fluid-applying device provided with a switching device such as a valve.

    摘要: An immersion lithography apparatus includes an optical member, a gap defined between the optical member and a surface disposed opposite the optical member being filled with an immersion liquid, and a fluid control device including a gas outlet through which a gas is supplied to prevent the immersion liquid from entering a surround area external to an exposure area. A flow velocity of the gas supplied from the gas outlet is controlled based on the motion of the surface such that a pressure exerted by the gas is made stronger or weaker depending on the motion of the surface.

    摘要: Methods and apparatus allow a liquid to be substantially contained between a lens and a wafer table assembly of an immersion lithography system. According to one example, an exposure apparatus includes a lens and a wafer table assembly. The wafer table assembly has a top surface, and is arranged to support a wafer to be moved with respect to the lens as well as at least one component. The top surface of the wafer and the top surface of the component are each at substantially a same height as the top surface of the wafer table assembly. An overall top surface of the wafer table assembly which includes the top surface of the wafer, the top surface of the wafer table assembly, and the top surface of the at least one component is substantially planar.

    摘要: A fluid control system for immersion lithography that uses an optical member such as a lens, a workpiece such as a semiconductor wafer with a surface disposed opposite to the optical member with a gap in between, includes a fluid-supplying device for providing an immersion fluid such as water to a specified exposure area in the gap, and a fluid control device that activates a force on the fluid so that the immersion fluid is retained in the exposure area and its vicinity at least while the immersion lithography operation is being carried out. A pressured gas may be caused to apply a hydrodynamic force on the fluid to keep it in its place.

    摘要: An environmental system controls an environment in a gap between an optical assembly and a device and includes a fluid barrier and an immersion fluid system. The fluid barrier is positioned near the device. The immersion fluid system delivers an immersion fluid that fills the gap and collects the immersion fluid that is directly between the fluid barrier and the device. The fluid barrier can include a scavenge inlet that is positioned near the device, and the immersion fluid system can include a low pressure source that is in fluid communication with the scavenge inlet. The fluid barrier confines any vapor of the immersion fluid and prevents it from perturbing a measurement system. Additionally, the environmental system can include a bearing fluid source that directs a bearing fluid between the fluid barrier and the device to support the fluid barrier relative to the device.
