摘要:
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.

A method and system are provided for printing a pattern on a photosensitive surface using a spatial light modulator (SLM). An exemplary method includes defining two or more exposure areas on the photosensitive surface, the exposure areas overlapping along respective edge portions of the exposure areas to form an overlap zone therebetween. Two or more exposure areas are exposed to print an image therein, the exposing extending through the overlap zone. The exposing within the overlap zone is then attenuated.

A method and system are provided for forming a pattern within an area of a photosensitive surface. An exemplary method includes performing a first exposure of the photosensitive surface in accordance with predetermined image data, wherein the first exposure occurs during a first pass and produces a first image within the area. The image data is adjusted to compensate for identified image deficiencies image deficiencies, the image deficiencies being within a region of the first image. A second exposure, of the photosensitive surface, is performed in accordance with the adjusted image data during a second pass.

A method and system are provided of using a patterning device. An exemplary method includes performing a first exposure of a surface corresponding to image data, determining an image deficiency within a region of the first image, adjusting the image data to compensate for the image deficiency, and performing a second exposure of the surface corresponding to the adjusted image data during a second pass of the patterning device with respect to the surface. The first exposure occurs during a first pass of the patterning device with respect to the surface to produce a first image on the surface.

A lithographic apparatus and method in which a relatively high resolution exposure, for example of a repeating pattern, is trimmed using a relatively low resolution exposure. According, a compromise between provision of a high resolution pattern and flexibility in the pattern to be formed is provided.
摘要:
To calibrate a lithographic apparatus having a programmable patterning means, a sensor, such as a CCD, CMOS sensor or photo-diode array, having detector elements larger than the size of a spot corresponding to a single pixel of the programmable patterning means is used. Pixels are selectively activated singly or in groups.
摘要:
In order to improve the productivity of a lithographic apparatus, a stage apparatus for holding two patterning devices is described. The patterning devices are arranged such that the distance between the patterns in the scanning direction corresponds to the length of the pattern in the scanning direction. By doing so, an improved exposure sequence may be performed by exposing a first die with a first pattern, skipping a second die adjacent to the first die, and exposing a third die adjacent to the second die using a second pattern.
