    Abstract: The invention relates to an alternating phase mask (1) having a branched structure consisting of two opaque segments. Two transparent surfaces segments (5a, 5b) are arranged on both sides of said segments or the components thereof respectively. The surface segments are provided with phases that are displaced by 180 DEG +/- DELTA alpha , whereby DELTA alpha is not more than 25 DEG . The surface segments (5a, 5b) are separated by at least one transparent surface boundary segment (6) whose phase is situated between the phases of the adjacent surface segments (5a, 5b).

    Abstract: Layers are patterned with a lithography method during the fabrication of integrated circuits. A mask, which may be reflective or transmissive, for carrying out the method. The photosensitive layers are exposed to radiation that is emitted by a radiation source. The radiation lies in the extreme ultraviolet region and is guided via the mask onto the photosensitive layers.

    Abstract: An alternating phase mask having a branched structure containing two opaque segments is described. Two transparent surface segments are disposed on both sides of the segments or the components thereof, respectively. The surface segments are provided with phases that are displaced by 180°±Delta alpha, whereby Delta alpha a is not more than 25°. The surface segments are separated by at least one transparent surface boundary segment whose phase is situated between the phases of the adjacent surface segments.

    Abstract: The invention relates to a phase shift mask for lithographically producing small structures at the limit of a resolution that is predetermined by the wavelength of the exposure radiation. The phase shift mask has first regions A and second regions B that effect a phase-shift relative to the first regions. The second regions are arranged beside the first regions for producing a sudden phase shift along the boundaries between the first and the second regions. Individual first regions touch one another via corners at points, at which the second regions also touch one another via corners. The result is that the boundaries between first and second regions merge at these points and these points are opaque to the radiation. The invention makes it possible to expose extremely small contact holes with just a single exposure and thus leads to a reduction of costs in the fabrication of integrated semiconductor circuits.

    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.
