    Abstract: The method of dynamically monitoring a reticle includes preventively macro monitoring and defect inspecting with regard to mechanical loading, including particle deposits or electrostatically induced damage, and energy load, including the associated changes to the reticle material and surface characteristics. Different surface distributions of the absorber layer as well as characteristics of the exposure system, such as N 2 purging of the projection lens/reticle area in order to reduce contamination and recrystallization on optically active surfaces are considered.

    Abstract: Tolerances to be communicated to the manufacturer for a photomask fabrication process that are assigned as desired values of feature sizes to be realized on the photomask, are freed of restrictions by predefining, for a first feature size, a first desired value and a first tolerance assigned to the first desired value. The real discrepancy between the first feature size and the first desired value is taken into account when predefining desired values assigned to the further feature sizes to be provided on the photomask. As a result, a value which corresponds to a first approximation to the permitted feature size tolerance on the semiconductor wafer is provided for the tolerances of the desired values.

    Abstract: A method of inspecting a mask or reticle, the mask or reticle being provided with a pattern to be transferred onto a semiconductor wafer, the pattern having a defect, includes the step of creating a plurality of logical zones and uniquely associating each of said logical zones with a surface area of said pattern. Then, an inspection rule representing a characteristic sensitivity for detecting a defect is associated with each of said logical zones. An image of said pattern is then recorded and compared with a reference image of an ideal pattern for locating a defect within said pattern. One of said logical zones is then identified with said located defect and that inspection rule which is associated with said identified logical zone is retrieved from a memory. The inspection rule is then applied to a characteristic of said defect for determining, whether said defect is to be repaired. A signal can be issued in response to said determination.

    Abstract: The method involves defining original data specifying an original layout and automatically computing new layout data similar to the original layout in terms of the geometry of a mask generated from the original data. The new data are computed based on rules related to deviations in layout geometry from a mask manufactured from this layout or modeled from the layout by following steps of a manufacturing process. The method involves predefining original data (12) specifying an original layout (10) and automatically computing new data (54) specifying a new layout (42) from the original data, whereby the new layout is similar to the original layout in terms of the geometry of a mask (22) generated from the original data. The new data are computed based on rules related to deviations in the geometry of a layout from a mask manufactured from this layout or modeled from the layout by following the steps of the manufacturing process. Independent claims are also included for the following: an arrangement for generating mask layout data, especially a data processing system, a program with a command sequence for implementation by a data processing system and an integrated circuit structure.
