Claims
- 1. A semiconductor integrated circuit including an interconnection array comprising a multiplicity of conductivity metallization lines located on a surface of a semiconductor body within a metallization area bounded by a pair of parallel edges,
- all the lines being mutually essentially parallel everywhere except in a plurality of separate crossing regions each extending between the pair of essentially parallel edges and in each of which every line, or every line except for the lines located closest to the edges, crosses at least one other line, whereby each of the lines is divided into a plurality of mutually essentially parallel segments each of which runs between successive crossing regions,
- such that the nearest neighboring segment with respect to each such line (e.g., 1) on one side thereof located between first and second successive crossing regions (d.sub.2, d.sub.3) is a segment of another line (e.g., 6) and
- such that the nearest neighboring segment with respect to such line (e.g., 1) on the one side thereof between the second and a third successive crossing region (e.g., d.sub.3, d.sub.4) is a segment of yet another line (e.g., 8) different from such another line (e.g., 6).
- 2. A circuit according to claim 1 in which the nearest neighboring segment with respect to each such line (e.g., 1) on the other side thereof, located between the first and second regions (e.g., d.sub.2, d.sub.3), is a segment of still another line (e.g., 4) different from such another line (e.g., 6) and from such yet another line (e.g., 8).
- 3. In a semiconductor integrated circuit, a metallization area located on a surface of the semiconductor, the area having first and second boundaries each of which is essentially parallel to a first (e.g., X) direction,
- a multiplicity of interconnection metallization lines located in said area,
- each of the lines comprising a sequential series of at least first and second successive segments (e.g., L.sub.3, L.sub.4) essentially parallel to the first (e.g., X) direction and of at least first and second successive non-parallel crossover portions (e.g., d.sub.3, d.sub.4),
- the first and second segments of all the lines respectively located within first and second separate segmental regions, and the first and second crossover portions of all the lines respectively located within first and second separate crossing regions, each of the segmental and the crossing regions extending essentially from the first to the second boundary,
- each of the lines in the first crossing region, or each of the lines in the first crossing region except for first and second outermost lines therein located closest respectively to the first and second boundaries, crossing a different one of the lines, and
- each of the lines in the second crossing region, or each of the lines in the second crossing region except for third and fourth outermost lines therein located closest respectively to the first and second boundaries, crossing a different one of the lines, the different one also being different from the line which was crossed by such line in the first crossing region.
