Abstract: An immersion lithographic apparatus is provided with a liquid confinement structure which defines at least in part a space configured to contain liquid between the projection system and the substrate. In order to reduce the crossing of the edge of the substrate which is being imaged (which can lead to inclusion of bubbles in the immersion liquid), the cross-sectional area of the space in a plane parallel to the substrate is made as small as possible. The smallest theoretical size is the size of the target portion which is imaged by the projection system. In an embodiment, the shape of a final element of the projection system is also changed to have a similar size and/or shape in a cross-section parallel to the substrate to that of the target portion.

Abstract: A porous member is used in a liquid removal system of an immersion lithographic projection apparatus to smooth uneven flows. A pressure differential across the porous member may be maintained at below the bubble point of the porous member so that a single-phase liquid flow is obtained. Alternatively, the porous member may be used to reduce unevenness in a two-phase flow.

Abstract: A charged particle inspection system may include a shielding plate having an aperture or more than one aperture, for example, to permit additional inspection by an additional instrument requiring a line of sight to the area of interest. A field shaping element, such as a window element or a raised rim, is placed at the aperture to prevent or reduce a component of an electric field.

Abstract: Systems and methods of observing a sample in a multi-beam apparatus are disclosed. A multi-beam apparatus may comprise an array of deflectors configured to steer individual beamlets of multiple beamlets, each deflector of the array of deflectors having a corresponding driver configured to receive a signal for steering a corresponding individual beamlet. The apparatus may further include a controller having circuitry to acquire profile data of a sample and to control each deflector by providing the signal to the corresponding driver based on the acquired profile data, and a steering circuitry comprising the corresponding driver configured to generate a driving signal, a corresponding compensator configured to receive the driving signal and a set of driving signals from other adjacent drivers associated with adjacent deflectors and to generate a compensation signal to compensate a corresponding deflector based on the driving signal and the set of driving signals.

Abstract: In a lithographic apparatus, a localized area of the substrate surface under a projection system is immersed in liquid. The height of a liquid supply system above the surface of the substrate can be varied using actuators. A control system uses feedforward or feedback control with input of the surface height of the substrate to maintain the liquid supply system at a predetermined height above the surface of the substrate.
