Abstract:
Various embodiments include computer-implemented methods, computer program products and systems for analyzing at least one feature in a layout representing an integrated circuit (IC) for an overlay effect. In some cases, approaches include a computer-implemented method including: modeling a topography of the IC by running at least one of a chemical mechanical polishing (CMP) model, a deposition model or an etch model on a data file representing the IC after formation of an uppermost layer; modeling the at least one feature in the IC for an overlay effect using the topography model of the IC; and modifying the data file representing the IC after formation of the uppermost layer in response to detecting the overlay effect in the at least one feature, the overlay effect occurring in a layer underlying the uppermost layer.

Claim (Index 7):
A computer program product comprising program code stored on a computer readable storage medium, which when executed by at least one computing device, causes the at least one computing device to analyze at least one feature in a layout representing an integrated circuit (IC) for an overlay effect by performing actions including:\n modeling a topography of the IC by running at least one of a chemical mechanical polishing (CMP) model, a deposition model or an etch model on a data file representing the IC after formation of an uppermost layer; modeling the at least one feature in the IC for an overlay effect using the topography model of the IC; and modifying the data file representing the IC after formation of the uppermost layer in response to detecting the overlay effect in the at least one feature, the overlay effect occurring in a layer underlying the uppermost layer, wherein the modifying of the data file includes modifying masking instructions in the data file to correct the overlay effect in the at least one feature, the modifying of masking instructions including:\n dividing a region containing the at least one feature into quadrants; \n calculating an overlay vector quantity for each of the quadrants; \n averaging the overlay vector quantities for all of the quadrants to determine a summation vector for the region; and \n shifting, in the mask instructions, a location of a mask used to form the at least one feature in an opposite direction and at an opposite magnitude as the summation vector for the region.
