Abstract:
1. A computer storage device comprising: computer data representing a range pattern comprising a plurality of positions of a corresponding plurality of line segments and at least one set of values comprising a maximum limit and a minimum limit on a position of an additional line segment; and computer instructions to instruct a processor in a computer to determine a match between said additional line segment of said range pattern and a trace in a plurality of traces formed by material in a portion of a layout of an integrated circuit (IC) chip within said maximum limit and said minimum limit, and to mark in a computer memory said layout as requiring a change in said portion to overcome a defect in fabrication of said plurality of traces based on said match; wherein multiple defective patterns are represented by said range pattern based on relative position of said additional line segment with respect to a line segment in said plurality of line segments.
