    摘要: A method for quantifying and improving layout quality of an IC is disclosed. The method includes receiving a drawn layout and placing essentially one dimensional measurement markers (chords) at various location in the drawn layout. This placement is done in such manner that contours of shapes in the drawn layout intersect a chord in at least two places. The length of the chord is defined as its portion delimited by the intersections, and a measurement of the chord is defined as obtaining its length. The drawn layout is subjected, with the exception of the chords, to a patterning simulation at a selected processing point. Following the simulation the chords are measured and the obtained lengths associated with the drawn layout and the processing point. The patterning simulation may be carried out at a variety processing points and the chord lengths following each simulation are associated with the respective processing point. The sets of lengths obtained at the various processing points are used to quantitatively evaluate the layout quality, to improve the layout quality and tune the processing window.
