A system that facilitates extraction of line edge roughness measurements
that are independent of proprietorship of a metrology device comprises a
structure patterned onto silicon with known line edge roughness values
associated therewith. A metrology device obtains line edge roughness
measurements from the structure, and a correcting component generates an
inverse function based upon a comparison between the known line edge
roughness values and the measured line edge roughness values. The
metrology device can thereafter measure line edge roughness upon a second
structure patterned on the silicon, and the inverse function can be
applied to such measured line edge roughness values to enable obtainment
of line edge roughness measurements that are independent of
proprietorship of the metrology device.
