    Abstract: PROBLEM TO BE SOLVED: To provide a structure, capable of simultaneously projecting a periodic line interval plane diffraction grating of a memory cell region and a peripheral structure pattern that is formed intricately. SOLUTION: The quality of image formation, when an image is simultaneously transmitted from a line interval plane diffraction grating and a peripheral structure including MUX row, is improved by using a quadrupole illumination. Four poles 14a to 14d of this quadrupole illumination extend in the longitudinal direction, and the axis 112 of the pole in the longitudinal direction is located vertical, with respect to the row direction of the grating row of a mask. Thus, the contrast of a structure image formation of the line interval planar diffraction grating, MEEF, and a process window can be improved. Meanwhile, the geometrical accuracy of the peripheral structure (particularly, MUX row) is stabilized by an illumination pupil 18, extending over the entire wide depth range of focus.

    Abstract: The invention relates to a method with which the direct convertibility of integrated semiconductor switching circuits into alternating phase masks can be verified. This ensues by explicitly localizing the phase conflicts occurring in the corresponding layout while solely using the technological demands placed on the design. The set of phase conflicts determined with the aid of this formalism is complete and minimal, and thus proves to be an optimal starting point for methods used in handling conflicts of this type.

    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: A method for eliminating phase conflicts that occur in the layout of a phase mask in a localized and automated manner. The method includes a first step in which a set of phase conflicts is completely determined exclusively by using the technical requirements of the design. The first step is an optimum starting point for the following second step for automatically handling and eliminating such conflicts.

    Abstract: A photoresist layer on a substrate wafer is exposed in first sections with a first exposure radiation and in second sections with a second exposure radiation that is phase-shifted by 180°. The first and second sections adjoin one another in boundary regions in which the photoresist layer is artificially not sufficiently exposed. Where a distance between these boundary regions is smaller than a photolithographically critical, least distance, the photoresist layer is exposed, at a first boundary region, with a third exposure radiation and at a second boundary region with a fourth exposure radiation phase-shifted by 180°. A trim mask provided for the process has a first translucent region and a second translucent region. The first light-transparent region and the second light-transparent region are fashioned such that the light passing through the first light-transparent region and the light passing through the second light-transparent region has a phase displacement of 180°.

    Abstract: Lithographic mask contains angular structure element (0) formed by two opaque segments (01,2). Structure element contains convex section (A) facing over obtuse angle (alpha). Adjacent to angular element is transparent structure (T), consisting of two transparent segments (T1,2), formed axis-symmetrically to angle (alpha) bisecting line (WH). Along this line in convex section, transparent structure is wider than standard width. Lithographic mask contains angular structure element (0) formed by two opaque segments (01,2). Structure element contains convex section (A) facing over obtuse angle (alpha). Adjacent to angular element is transparent structure (T).Transparent structure is formed in two parts, i.e. consisting of two different transparent segments (T1,2), formed axis-symmetrically to angle (alpha) bisecting line (WH). Along this line in convex section, transparent structure is wider than used standard width of transparent segments.

    Abstract: An improvement of the imaging quality with simultaneous transfer of line-space gratings and peripheral structures including a MUX space is achieved using a quadrupole illumination whose poles are formed in elongate fashion and whose longitudinal axes are arranged perpendicular to the orientation of the lines of the line-space grating arranged on a mask. The structure imaging of the line-space grating is improved with regard to contrast, MEEF, and process window, while the geometrical fidelity of the peripheral structure, in particular of the MUX space, is stabilized over a wide depth of field range.
