摘要: A lithography mask has an angled structure element (O) formed by a first opaque segment (O1) and by a second opaque segment (O2). The structure element has at least one reflex angle (α). The angled structure element (O) includes at least one convex section (A) facing the reflex angle (α). At least one transparent structure (T) adjacent to the angled structure element (O) is provided at the convex section (A) of the angled structure element (O). The transparent structure (T) is formed in separated fashion at the convex section (A) of the angled structure element (O) and thus comprises two distinguishable transparent segments (T1, T2) formed at least in sections essentially axially symmetrically with respect to the angle bisector (WH) of the reflex angle.

摘要: A method is provided in which a pattern for a phase-shifting mask is firstly corrected in a first correction step. Subsequently, the pattern for the trimming mask is corrected with use of the corrected pattern for the phase-shifting mask in a second correction step. Mask data for the production of very-large-scale integrated circuits can be corrected in a simple manner by means of the two correction steps performed in succession.
