Abstract:
1. A method for the lithographic fabrication of a microelectronic component with optical proximity correction, which comprises: imaging a main structure with an auxiliary structure onto a substrate by exposing; selecting at least one correction value for an optical proximity correction in dependence upon a spacing between two parts of the main structure or a spacing between neighboring main structures and a presence of the auxiliary structure between the two parts of the main structure or between neighboring main structures; forming an auxiliary quantity for the auxiliary structure for the purpose of determining a manner wherein the correction value is specified, and thereby setting a largest auxiliary quantity to be smaller than a smallest spacing between the parts of the main structure; concluding with a program for the optical proximity correction whether the auxiliary structure is present between two parts of the main structure ox between neighboring main structures; and setting the auxiliary quantity in a proximity layer.
