Integrated semiconductor structure with incorporated alignment markings

Claim 1

A semiconductor integrated circuit structure formed on a substrate and composed of a plurality of groups of integrated circuit chips which are to be separated from one another after manufacture, each chip being in the form of an elongated strip having a short dimension and a long dimension which is markedly longer than the short dimension, the chips of each group being manufactured so that adjacent chips of each group are spaced from one another by linear scribe lines along which the substrate is to be cut to separate the chips, the scribe lines including a plurality of mutually parallel first linear scribe lines extending parallel to the long dimension of said chips, each said first linear scribe line having a width perpendicular to the long dimension of said chips, and at least one second linear scribe line extending parallel to the short dimension of said chips and being located between adjacent chips of the respective group, said second linear line having a width perpendicular to the short dimension of said chips, wherein the width of said at least one second linear scribe line is greater than the width of at least one of said first linear scribe lines, said structure further including at least one of an alignment mark and a process monitor transistor within said second linear scribe line.
