Abstract: A lithographic apparatus includes a patterning device that patterns a projected beam. The patterning device includes an array of cells that contain a polar fluid, a non-polar fluid, and an electrode. A potential difference across the electrode and the polar fluid causes displacement of the non-polar fluid. Based on a difference in refractive index between the polar fluid and the non-polar fluid, a beam of light which passes through the cell will have its phase changed in dependence on the relative thickness on the polar and non-polar fluids and on their refractive indices.

Abstract: A lithographic apparatus is provided that uses an array of individually controllable elements to pattern the beam of radiation. The critical dimension uniformity of a substrate patterned using the apparatus is improved by adjusting the pattern data provided to the array of individually controllable elements to compensate for process variation.

Abstract: The present invention provides systems and methods for maskless lithographic printing that compensate for static and/or dynamic misalignments and deformations. In an embodiment, a misalignment of a pattern formed by a spatial light modulator is measuring during printing. Rasterizer input data is generated based on the measured misalignment and passed the rasterizer. The rasterizer generates pattern data, based on the rasterizer input data, that is adjusted to compensate for the measured misalignment. The pattern data generated by the rasterizer is passed to the spatial light modulator and used to form a second pattern, which includes compensation for the measured misalignment. In an embodiment, deformations caused, for example, by a warping a surface of the spatial light modulator are measured and used by the rasterizer to generate pattern data that compensates for the deformations.

Abstract: A lithographic apparatus and method are used to pattern a substrate. The system and method includes an illumination system for supplying a projection beam of radiation, an array of individually controllable elements for imparting the projection beam with a pattern in its cross-section, and a substrate table for supporting the substrate during an exposure operation. A projection system projects the patterned beam onto a target portion of the substrate. A control system sends a control signal for setting each said individually controllable elements to a desired state. A compensation device for adjusting the control signal applied to a first individually controllable element based on the control signal to be applied to at least one other individually controllable element. This can be done to reduce image degradation arising from cross-talk between individually controllable elements.

Abstract: A lithographic projection device according to the present invention includes a first radiation source which supplies a projection beam of radiation of a first type, a mask table for holding a mask, a substrate table for holding a substrate and a projection system for imaging a portion of the mask, irradiated by the projection beam, onto a target portion of the substrate. Further, a second radiation source supplies a second beam of radiation of a second type which can be directed onto the substrate and a controller which patterns the second beam of radiation so that it impinges on the substrate in a particular pattern. The two radiation beams are controlled such that the sum of the fluxes of the radiation of the first and second type on the substrate causes an elevation of the substrate temperature which is substantially constant across at least a given area of the substrate.

Abstract: In an electron optical system a monopole shaped magnetic field is introduced enabling an aberration free imaging writing or detection in the system. Apparatus based on this field distribution result in improved secondary electron detection such as for chip inspection, in improved resolution in Auger electron detection for analysis, in a higher exactness in chip production in an electron beam pattern generator and in an electron beam image projector in which now also size reduction can aberration free be introduced.

Abstract: An objective lens in an electron microscope is adapted to detection of Auger electrons. Using an additional lens field, preferably including the use of a VAIL lens, the electrons to be detected are spiraled to a selection space. Between the lens field and the selection space a preferably displaceable, magnetic diaphragm is arranged for the separation of lens fields.
