    摘要： Ghost reflections in a catadioptric scatterometer objective are excluded from an angle-resolved spectrum measurement by using a partial pupil for illumination and for the measurement excluding the area of the pupil plane that has been illuminated. Ghost reflections are reflected back into same point in the pupil plane. The ghost reflections do not interfere with the signal in the non-illuminated area of the pupil plane. An illumination system provides a beam of electromagnetic radiation to illuminate a first area in an illumination pupil plane of the objective. The objective is arranged as to illuminate the substrate with the beam of electromagnetic radiation. The illumination pupil plane is the back projected image of the pupil plane of the objective and is also imaged into the measurement pupil plane at the back focal plane of the objective, via auxiliary optics. A detector is configured to measure an angle resolved spectrum arising from the illumination of the substrate, in a measurement area of the measurement pupil plane of the objective excluding an area corresponding to the first area.

    摘要： A lithographic system and method are provided that allow for variations of a basic device design to be generated without substantially increasing the cost of the data path hardware. The lithographic apparatus includes an array of individually controllable elements, a control system, a first data buffer, and a second data buffer. The control system provides control signals to the array of individually controllable elements. The first data buffer stores pattern data that corresponds to a pattern to be exposed on a plurality of areas on the substrate. The second data buffer stores pattern variation data, corresponding to at least one change to a part of the pattern. The control system is configured, such that at least one variation of the pattern is exposed on one of the areas on the substrate with the pattern variation data.
